Zirconium silicate has the characteristics of high melting point, high hardness, excellent high temperature resistance and corrosion resistance, and is widely used in many fields. The following is its application status:

Ceramic field: It is a commonly used additive in ceramic production. In daily-use ceramics and sanitary ware, it is mainly used for high-temperature opacified glazes. The addition amount in daily-use ceramics is 8%-12%, and in sanitary ware is 8%-14%. It can improve the hardness and glossiness of the glaze surface, and enhance wear resistance and chemical corrosion resistance. In glazed interior wall tiles, it is used for cosmetic soil and zirconium white frit, with a content of 4%-10% and 10%-12% respectively, which can increase whiteness and adjust the expansion coefficient. In porcelain polished tiles, the content reached 3%-5% when used in ultra-white bricks in the early days. Later, due to radioactive problems, enterprises generally reduced the amount to 1%-2%, but the amount added in some ultra-white line points can reach 3%-5%. In addition, 1% zirconium silicate or zircon powder is also added to glass products to increase stability.
Glass field: It can be used as a raw material for glass, which can increase the transparency, hardness and wear resistance of glass and improve the physical properties of glass. It is often used to produce emulsified glass and high-refractive index optical glass, etc. Zirconium silicate is used to manufacture glass parts of optical instruments and high-end watches.
Enamel glaze field: It is one of the important raw materials for the production of enamel glaze. Adding zirconium silicate can improve the hardness, wear resistance and corrosion resistance of the enamel glaze, so that the enamel products have better quality and appearance.
Refractory field: Due to its high melting point (about 2500 degrees Celsius), it is widely used in refractory materials, such as glass kiln zirconium ramming materials, castables, spray coatings, etc. Zirconium silicate can improve the high-temperature stability, thermal shock resistance and erosion resistance of refractory materials, and is widely used in high-temperature industrial furnaces, glass melting furnaces, cement kilns and other equipment.
Electronic materials field: It has the characteristics of high-frequency response, high Q value and low loss, and can be used to manufacture microwave electronic components, such as high-Q value resonators, filters, etc.
Other areas: Zirconium silicate can also be used in some cements as beads for grinding and grinding; zirconium silicate and hafnium silicate films produced by chemical vapor deposition (CVD) technology can be used as high dielectric constant materials in semiconductors to replace silicon dioxide; its compounds are also being studied for medical applications, for example ZS-9 is a zirconium silicate specially designed to capture potassium ions in the digestive tract.
