Description
Technical field
The present invention relates to ceramic technology field, and in particular to a kind of novel bone porcelain blank and its preparation technology.
Background technology
Bone China original claims bone china, is generated from one of Britain high-grade porcelain kind, significantly commonly abbreviated as china, it be
Animal bone ash, the porcelain through high-temperature firing are mixed in traditional ceramic raw material.China belongs to soft-paste, used Animal Bone
Ash is generally first-class ox bone, thus china porcelain is fine and smooth, and glaze is smooth, and gloss is soft, just like sense of the fat like jade, extremely shows natural, graceful and poised China
It is expensive, and with higher transparency and certain mechanical strength.Its owner " thin as a piece of paper, bright such as mirror, white as a jade, sound such as single sonorous stone "
Good reputation.In domestic ceramics, the application of Bone China is the most high-grade porcelain kind generally acknowledged in the world today widely, deep by wide
Big consumer's likes.
Although Bone China is noble, there are its fatal weakness, i.e. its thermal shock resistance to can not show a candle to traditional K2O-Al2O3-
SiO2System porcelain and talcum daily-use fine.Standard GB/T/T13522-2008《Sclerotin porcelain》Anti-thermal shock professional etiquette is set to 140-20
DEG C heat exchange is not split once, lower than the thermal shock resistance of common domestic porcelain 40 DEG C.The bone china product water of current China's production
The middle exchange temperature difference is how below 140 DEG C, having or even below 100 DEG C, even if the temperature difference exchanged in high-quality bone china product water
Also 160 DEG C are can only achieve, its thermal shock resistance is poor, have impact on promoting the use of for china.
The content of the invention
It is an object of the invention to provide a kind of novel bone porcelain blank and its preparation technology, thus resist made from blank
Thermal shock resistance is good, and intensity is high, even tissue and tough, the excellent combination property that compacts.
To realize object above, the present invention is achieved by the following technical programs：
A kind of novel bone porcelain blank, contains following components in percentage by weight：Bone meal 50-55%, kaolin 24-
28%th, quartz 9-11%, feldspar 8-10%, lithium porcelain stone 0.38-0.52%, zircon sand 0.8-1.6%, nano-aluminium oxide
0.4-0.8%.
Preferably, the novel bone porcelain blank contains following components in percentage by weight：Bone meal 54%, kaolin
26%th, quartz 10%, feldspar 8.8%, lithium porcelain stone 0.46%, zircon sand 0.14%, nano-aluminium oxide 0.6%.
In the present invention, kaolinic particle diameter is 1-10 μm, and quartzy particle diameter is 1-35 μm, and the particle diameter of feldspar is 0.5-5 μm,
The particle diameter of lithium porcelain stone is 1-10 μm, and the particle diameter of zircon sand is 2-8 μm.
Quartz is made up of the quartz of the different-grain diameter of following percentage by weight：Particle diameter for 25-35 μm quartz sand 5-10%,
Particle diameter is 15-20 μm of quartz sand 10-15%, particle diameter is 5-10 μm quartz sand 50-60%, the quartz sand that particle diameter is 1-4 μm
20-30%.
Bone meal is preferably bovine bone powder in the present invention, but is not limited to it is also possible to use bovine bone powder and other in bovine bone powder, the present invention
Bone meal (such as lamb bone meal, Os Sus domestica powder) carries out collocation and used.
The preparation technology of above-mentioned novel bone porcelain blank comprises the following steps：
(1) each raw material is weighed by recipe ratio；
(2) bone meal is put into baking oven and dried at 65-70 DEG C, placed into high-temperature calcination stove, with 7-9 DEG C/min speed
Degree cools to room temperature with the furnace after being warming up to 1120-1150 DEG C, insulation 2-3h, is ground to particle diameter for 0.5-3 μm；After grinding
Bone meal and other raw materials mix, add water and be configured to Bone China slurry, the Bone China mud cake that moisture content is 18-20%, system is made
Obtain Bone China blank.
The beneficial effects of the invention are as follows：
Proper amount of feldspar is added in the present invention, makes porcelain body glass phase ratio moderate, i.e., there is provided enough continuous matrix,
Make porcelain body thermal coefficient of expansion suitable again, add proper amount of quartz, quartz is conducive to the porcelain of base substrate, and can improve glass phase
Swelling properties.In sintering procedure, the CaO that is decomposited after dewatering kaolin with bone meal reaction generation anorthite, anorthite with
Tricalcium phosphate constitutes porcelain body skeleton together, can strengthen Bone China intensity and thermal shock resistance, bone meal and kaolin reasonable mixture ratio, i.e.,
Substantial amounts of anorthite can be generated, excessive kaolin mullitization is avoided again, so as to avoid the brilliant optics to Bone China of mullite
The influence of performance.
K in Bone ceramic green body can be reduced by adding a small amount of lithium porcelain stone2O、Na2O content, the Li contained by lithium porcelain2O has relatively low
Thermal coefficient of expansion, be conducive to improving the thermal shock resistance of Bone China, while lithium porcelain stone can also improve the high temperature viscosity of base substrate, enhancing
The performance of high temperature deformation is resisted, increases the density and intensity of base substrate.Add appropriate zircon and can further improve the tough of Bone China
Property, rupture strength and thermal shock resistance.Stronger small-size effect, the skin effect that the nano aluminium oxide of addition has cause
The surface of crystal grain can increase, and material can be made to reduce sintering temperature, improve densification rate.
The present invention is using the suitable each raw material of levigate and granularity, then carries out batch mixing base, and this technique is common better than various raw materials
Mix grinding technique, makes final obtained Bone China performance more excellent.The grain composition of quartz is particularly effectively controlled, size is not
With the quartz particles reasonable mixture ratio of particle diameter, the wherein quartz particles of small particle because its specific surface area is big, solid phase reaction area is big,
Easily melt and dissolved, the quartz particles of larger particles then form fillet in periphery, and crystal grain flawless, glass itself is mutually filled in space
Between, increase the bulk density of porcelain body, so that mechanical strength is improved, the coefficient of expansion reduces, so as to improve the anti-of Bone China
Thermal shock resistance.It and bone meal is once calcined again before batch mixing, can effectively strengthen the mobility of Bone China slurry, and can make to be made
Bone China combination property it is more excellent.
