Zirconium silicate is a kind of composite oxide material with high melting point, chemistry and phase. It is widely used in refractory materials and zirconium based pigments. Zirconium silicate sintered together has excellent high temperature resistance and is also an important candidate for high temperature layout. However, natural zirconium silicate is usually rich in impurities. When it is used in high temperature environment, natural zirconium silicate will differentiate and lose its excellent function, so it can be artificially assembled High purity silicic acid is an effective way to solve this problem. For this reason. Researchers have discussed a number of wet chemical methods for the preparation of zirconium silicate, during which sol gel method has attracted much attention due to its high purity, good uniformity, high uniformity and high temperature required for making the temperature lower than traditional methods, such as water sol-gel sol-gel method and lithium ion compound.

After the heat treatment, the zirconium silicate ring was formed. Zirconium silicate was studied. When the hydrolysis sol-gel method was adopted without introducing other additives, in the 90s of last century, foreign researchers put forward a non hydrolytic sol gel technology four. The process of non hydrolytic sol gel is to react with alkyl oxide by metal halide and oxygen supply after nucleation without nucleation. Instead of reaction, the metal bridge oxygen bond is formed by direct polycondensation. At present, this method has been successfully applied to a variety of composite oxides. However, when this method is used to form zirconium silicate for precursor materials, the composition temperature is as high as 10 ℃ because no mineralizer is added. For this reason, we have introduced the mineralizer UF to form the temperature drop. That is to say, the non hydrolytic sol gel method was used. The industrial pure anhydrous four zirconium chloride and tetraethyl orthosilicate were used as precursors, and the alkali halide or alkaline earth metal halides were used as mineralizer. Based on the preliminary discussion, the influence of preparation technology on the formation of zirconium silicate was systematically discussed.

Because of the use of low-quality materials, ceramic factories usually add 2-3% zirconium silicate to the green body to increase the whiteness of the green body, but it can cause the radioactive overrun of the green body. According to the reaction information of each ceramic factory, the radioactivity of this kind of brick made by adding 3% Australian sand into polished brick does not exceed the cost, and can reach the class a specification. If it is calculated based on this, then the standard radioactivity content in the green body is about class A, that is to say, the radioactivity of the formula itself is appropriately high when the green body is not added with zirconium silicate, and adding 3% zirconium silicate just completes the change of radioactivity from quantity to quality. According to the above data, the author calculated all kinds of zircon sand manufacturing, this accounting result is only for reference, because the difference of the radioactivity of the green body itself leads to the change of data is normal. This accounting result is based on the radioactive results of the tested samples. The radioactive fluctuation caused by the variation of zircon placer producing areas is not included.
