Crystalline, high-purity decanoic acid = narrow distribution, excellent dispersibility, and high, for example, in order to reduce the size, weight, and high-capacity 1286537 of the ceramic capacitor, the particle size of calcium titanate must be reduced. Shorten the interval between laminations and increase the number of laminations. However, in general, once the particle size of calcium barium titanate becomes small, although the c/a ratio becomes low and is close to cubic crystal, once the c/a ratio becomes low, the dielectric property is lowered as a dielectric material. The electrostatic capacity will become smaller when used. Therefore, even if the particle diameter is small, it is desirable to exhibit a high e/a ratio of titanate. In addition, a high c/a ratio of 7 is required to be crystallized in the south. Further, when the calcium titanate tantalum powder is mixed with a solvent and then slurried or gelatinized, once the powder is agglomerated, the sintered density is lowered, and electrical characteristics such as withstand voltage and migration are caused. In addition, the impurities contained in the titanic acid touch will not cause electrical properties. In order to reduce the size, weight, and high performance of electronic components, it is necessary to develop titanium with a small particle size and a narrow distribution. _barium. ^ ^ , Knowing the method of manufacturing titanic acid, niobium can use the following technical means.

The alkoxy method is used to carry out the hydrolysis to obtain a ruthenium drive, etc. The μ-based metal is used as a raw material. In addition, in the conventional method of producing barium titanate, the titanium compound is subjected to hydrolysis of a product and a water-soluble oxime reaction 1286337 (Patent Document 1); in a strong base, a method of pushing a sputum (Patent Document 2) Patent Document 3) 'Fangliang of the reaction between bismuth/di-glue and ruthenium compound.) 4 Still keen to develop such a synthesis method. Although the manufacturing cost of the solid phase method is low, the particle size of ruthenium particles becomes large. The problem is that if the formed titanic acid is concerned about the widening of the particle size distribution, the fineness cannot be improved. If the particle size is small, the crystal structure is skewed, and it is impossible to obtain a suitable ϋ 2 due to pulverization and powder. Disadvantages, 1 Ν 'Ν performance of barium titanate In addition, although the oxalate method can obtain a carboxylic acid-based carbonate group, which is attributed to the damage of the vehicle remaining in the impurity, the electrical property is lowered, and the titanic acid having excellent electrical properties is obtained by the water captured by the portion.钡 之 之 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 In order to have special equipment at high temperatures, it is necessary to increase the cost of the bismuth sulphate steel to obtain more titanium particles than the hydrothermal synthesis method, but it is caused by the water trapped inside.

The reason for the axis is not yet the same, but the more easily the I In n, the calcium ion of the 15 1286537 is more likely to react with the titanium oxide. The solution t is preferably at least 13 or more, more preferably 14 or more. Alkaline compounding limits the saturation of water relative to the water in its test compound. In a preferred embodiment, in the presence of the enthalpy of the test compound, the amount of residual ions is less than one percent of the amount of the implant, and one or less of one of the two After the reaction and the synthesis of titanium, the oxidative dance, the amount of dance ions until the amount of the knife 1 is placed, preferably less than one thousandth, so that it is anti-deer and low. The raw material of barium hydroxide, i oxidation "titanium bismuth!: Erxi Moore, preferably less than a thousandth - Molar calcium titanate should be 4tii 丄: ί, χ, γ value controlled to percent - It is of the order of magnitude, and it is more than one-thousandth of an order of calcium titanate. The amount of u ions and the amount of _ sub-components are the liquids of the reaction solution, such as luminescence or atomic absorption. The reaction is carried out as described above, and the total concentration of each ion in the solution after the reaction is allowed to stand until it is less than one thousandth, and is allowed to react until it is inverted. As a result, raw materials such as cerium oxide and titanium oxide which are unreacted by the increase in titanic acid are increased, and the crystallinity is improved. The reduction rate of the total concentration after the reaction can be obtained by the following formula (3). ([A1'] + [A2']) xL2/ ([A1] + [A2]) (3) [A1 ], [A2']: Convert the A1 ion weight in the solution after each reaction The molar concentration (mGl/ml) obtained afterwards. ^ A2 [Al], [A2]: The number of moles of hydroxides that are reacted separately. L2 ··Reaction liquid amount (ml). The most industrial way of synthesizing this reaction is by heating and disturbing. In particular, when mechanical agitation is performed, suitable materials are mixed with each other. In addition, 16 1286537, because the reaction solution is alkaline, it is easy to absorb c〇2 in the air. Therefore, it is better to make the reaction liquid not in contact with air. Seal or spray an inert gas, etc., and carry out the reaction on both sides. Once c〇2 is absorbed by the reaction solution, it contains a sulphate group in the reaction solution. The carbonic acid group (carbonic acid type includes C〇2, pj2C〇3, and (7)32-, reacts with barium hydroxide or calcium hydroxide to form stable barium carbonate calcium carbonate. Barium carbonate or calcium carbonate does not oxidize Titanium reacts, but it tends to remain as an impurity in calcium titanate. Therefore, it is preferable to control the carbonation rate in the reaction liquid (c〇2 conversion value. Hereinafter, unless otherwise specified, The same.) By controlling the concentration of the carbonic acid group, it is possible to stably produce high-purity titanic acid per ruthenium. The concentration of C〇2 in the reaction liquid is 0 to 500 ppm by mass, preferably 0 to 200. = ppm, more preferably 0 to 100 ppm by mass. In order to reduce the degree of carbonation in the reaction liquid, it is preferred to remove the carbonic acid by heat treatment before dissolving the water before the alkaline compound is dissolved. The acidity of the acid touch is expected to increase the reaction temperature as much as possible. For the k* reaction temperature, although the hydrothermal reaction of the KKTC to the critical temperature of the solution is possible, it is necessary to have a safety device such as an autoclave. It is better to boil to 95. (: Above, after maintaining the temperature. The reaction time of barium hydroxide and titanium oxide is usually 2 hours or more, f is good for 4 hours. In addition, after the oxidation of 1$ is placed, the pass is 2 small. Above the sundial, it is more preferably 4 hours or more, more preferably 6 hours or more. The impurities which are adversely affected by the electrical properties of the titanate include: ^ ίίίί ΐ or an anion, etc. In order to remove such impurities, The second step is to use various methods such as electric reduction, ion exchange, water washing, pickling, permeable membrane, etc., to carry out the treatment of the slurry of the reaction ii. However, among these methods, the simultaneous and impurity ions are At the same time, in the case where the yttrium contained in the titanium yttrium is partially dissolved in the syrup, it will become difficult to supplement the required ratio, because the crystallization towel will also have defects, and the surname The shape must be taken care of. In addition, because the reaction liquid is an inspective hole, carbon reduction will be easily treated in this way. Therefore, the carbonate contained in 12g_钡中17 1286537 will be more In this case, when raw materials with less impurities are selected, The anti-purification of the calcination is prevented, and it is more suitable for the temperature range of one atmosphere or under reduced pressure and the room temperature to the calcination temperature after the end of the synthesis reaction, by evaporation, sublimation and/or After the thermal decomposition, the impurities are formed into a gas and then removed. At this time, it is preferable to simultaneously decompose the basic compound contained in the alkali solution to form a gas and then remove it. Generally, the calcination system is for oxidizing the composite containing titanium. On the other hand, by performing calcination, it is possible to carry out the formation of a gas by bursting, f and/or thermal decomposition, and then removing the impurities, and removing the impurities by this means: The organic amine having a low carbon number, the hydroxide of the neon, and the impurities contained in the towel are organic matter, carbon, etc., and iff is carried out at a temperature τ of 35 G to 12 GG °C. Environmental gases and ..., any restrictions, usually in the air or under reduced pressure. ,, in the case of Renlin's Difficulty 4 reduction or increase in crystallinity, it is better to carry out the solid-liquid separation of the slurry and then enter the steps of g ίΓϊίΓη, shrinking, filtering and/or drying and disintegrating. By means of the rhyme, it is possible to remove impurities dissolved in the solution. In order to change ί it', it is also possible to condense the dirty dispersant.

Further, '5..., the titanium oxide sol used in the present invention is not particularly limited, and it is desired that 18 1286537^ has a brookite-type crystal titanium oxide sol. Alternatively, it is desirable to obtain a titanium oxide sol obtained by hydrolysis of a titanium salt in an acidic solution. In the case of a brookite-type crystal, it may contain brookite-type gentils, titanium, or rutile-type crystals or anatase-type crystals.曰3 In the case of rutile-type crystal or anatase-type crystallized titanium oxide, the ratio of the titanium oxide-titanium-type crystalline titanium oxide is not particularly limited, and is usually from 1 to just 0%, preferably from 10 to 100% by mass.
