雲母積層セラミックの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a composite mica laminated ceramic having insulation properties, heat resistance, and easy machining.

すべて合成樹脂を接着剤として製作されており、主に電
気絶縁材料として使用される。[Conventional technology] Conventionally, products manufactured using mica include laminated mica, which is made from natural mica, and laminated sheets made of laminated mica, and glass cloth for reinforcing the laminated mica. There are glass mica etc. which are made by gluing . All of these products are manufactured using synthetic resin as an adhesive and are primarily used as electrical insulation materials.
特に耐熱性を要求される製品ではケイ素樹脂が使用され
る。Silicone resin is especially used in products that require heat resistance.
これらの製法ではいづれも接着剤が合成樹脂であるから
、耐熱的には２００〜３００℃以上の高温を期待するこ
とはできない。Since the adhesive in all of these manufacturing methods is a synthetic resin, high temperatures of 200 to 300° C. or higher cannot be expected in terms of heat resistance.
また、天然雲母自体が６００〜８００℃に至れば結晶構

から、天然雲母を素材とした製品に８００℃以上の耐熱
性を要求するのは極めてむずかし《、従って従来技術で
は８００℃以上の耐熱性を有する雲母積層物の製作はで
きない。Furthermore, if natural mica itself reaches a temperature of 600 to 800°C, it will release the hydroxyl groups in its crystal structure as water and the crystal will collapse, so products made from natural mica are required to have heat resistance of 800°C or higher. Therefore, it is not possible to produce a mica laminate having a heat resistance of 800° C. or higher using conventional techniques.

組み合わせの量および質的関係において差異を生じる。At this time, for example, when silica sol, alumina sol, lithium silicate, etc. combine with fluoride or magnesia,
On the other hand, alumina sol, potassium silicate, etc. coagulate when combined with lithium carbonate, and are finally solidified. This coagulation causes differences in the quantity and qualitative relationship of each combination.
本発明に係る雲母組成スラリ一物は凝固が極めて短時間

硬化して固化する。In the case where the mica composition slurry according to the present invention solidifies in a very short time, gelation progresses slowly over several tens of minutes and the viscosity increases, but after a certain period of time, solidification rapidly occurs and hardens. and solidify.
そこで、本発明は前述のように調整したスラリ一物を、

Before thickening begins, the slurry is applied to a composite mica film made of fluorine phlogopite and laminated to the desired thickness, molded and left to stand, and the slurry hardens due to the interaction of the materials to form a laminate.

る。As described above, according to the manufacturing method of the present invention, the manufacturing process is extremely simple, efficient, and safe since it is a sintering method in which layers are laminated into the required shape at room temperature and then heated and sealed. Work continues. In addition, when producing a colored composite mica multilayer ceramic, in addition to the mica composition material, an appropriate amount of oxides such as copper, iron, nickel, manganese di cobalt, or salts thereof are added as a coloring agent. A colored composite mica multilayer ceramic can be produced by applying the mixed slurry to a composite mica film and bonding it.

みならず耐熱衝撃性も著しく低下する。Although the present invention has been described above, the size of the crystals that are precipitated when fluorinated mica is synthesized needs to be varied depending on the intended use. That is, mica ceramic with large crystals has a soft hardness and is easy to process, but its mechanical strength is reduced. In addition, if the quality is poor, the material will not only be hard and difficult to process, but also have a significantly reduced thermal shock resistance.

セラミックを製作し得る。Based on the above, we mixed two types of mica composition slurry: a mica composition slurry that suppresses crystal growth and a mica composition slurry that has good growth properties, applied this to a composite mica film, and heated and bonded it to crystallize it. Then, depending on the blending ratio, it is possible to produce a composite mica laminated ceramic having processability most suitable for the purpose of use.

る。[Effects of the Invention J The method for manufacturing the composite mica laminated ceramic according to the present invention is as described in detail above, in which a slurry having a fluorine mica composition is prepared, and then coated on a fluorine phlogopite composite mica film and laminated. By firing this laminate, new mica is generated between the layers to produce a layered ceramic layered in an eyebrow shape, so there is no need to use adhesives other than mica. Therefore, since there is no intervening foreign matter, the original characteristics and functions of mica are not impaired at all. Furthermore, the size of the crystals that precipitate during synthesis can be selected depending on the purpose of use, and the layered ceramic after sintering is not only easy to machine, but also has excellent heat resistance and thermal shock resistance. It has the following effects: it can be used as an electrically insulating material, and it can also be used as an electrically insulating material.
