Application

1. Ceramic industry
(1) Opacifiers and whitening agents: used in glazes for architectural ceramics, sanitary ceramics, daily ceramics and handicraft ceramics, by forming baddeleyite crystals to scatter light, thereby improving the whiteness and hiding power of the glaze.
(2) Improving the bonding between body and glaze: enhancing the bonding strength between the ceramic body and the glaze layer, reducing the risk of cracking.
(3) Improving the hardness of the glaze: making ceramic products more wear-resistant and scratch-resistant.
2. Glass and enamel
(1) Emulsified glass: used to make opalescent glass, increasing transparency and texture.
(2) Enamel glaze: used as an opacifier to improve the whiteness and uniformity of enamel products.
3. Refractory materials
Used in ramming materials, castables and spray coatings for glass kilns, due to their high melting point (2500℃) and corrosion resistance, they can withstand high temperature environments.
4. Grinding media
Zirconium silicate beads are used for ultrafine grinding in the coating, ink, cosmetics and other industries, replacing traditional glass beads. They have high hardness (Mohs hardness 7.5), wear resistance and chemical stability.
5. Other fields
(1) Plastic filling: Enhance the heat resistance and insulation of materials such as epoxy resin and silicone.
(2) Medical research: As a carrier or coating agent, it is used for drug sustained release or functional materials (such as the red glaze of Chinese red ceramics).
Nuclear energy and military industry: Zirconium alloys are used as nuclear reactor sheath materials, and the radioactive properties of zirconium silicate are studied and utilized in specific medical scenarios.
