10 Common Zirconium Products and Their Applications

1. Zirconium Silicate

Zirconium silicate is an important variety in traditional zirconium products. The product is made of zircon sand, which can be obtained after grinding, calcining and powdering. It is a high-quality and cheap opacifying agent for ceramic glazes.

Zirconium silicate is mainly used for color glazes of architectural ceramics, daily-use ceramics and electric porcelain. It is also widely used in high-grade refractory materials, precision casting, emulsified glass and other industries.

2. Zirconium Carbonate

Zirconium carbonate is a source of zirconium that is insoluble in water but is easily transformed into other zirconium compounds. It is mainly used as an additive for cosmetics, waterproofing agent, flame retardant, opacifying agent, and surface aid for fibers and paper, and can also be used to prepare zirconium-cerium composite catalytic materials. It is an important raw material in the textile, papermaking, paint, and cosmetic industries, and its consumption has been increasing in recent years.

3. Zirconium Oxychloride

Zirconium oxychloride is the main raw material for the production of other zirconium products such as zirconium dioxide, zirconium carbonate, zirconium sulfate, composite zirconium oxide, and the separation of zirconium and hafnium to prepare metal zirconium and hafnium. In addition, it can be used in textiles, leather, rubber additives, metal surface treatment agents, paint drying agents, refractory materials, ceramics, catalysts, fire retardants, and other products. The primary source material for zirconium oxychloride is zircon sand.

4. Fused Zirconia

Fused zirconia is mainly used in the production of glazes and refractory materials. Due to the high content of impurities in fused zirconium, its use is sometimes limited.

5. Zirconium Sulfate

Zirconium sulfate is an intermediate raw material for the production of zirconium chemicals and metal zirconium and hafnium. It is also an important raw material for the production of leather tanning agents, wool treatment agents and paint surface oxidants. Additionally, it can be used as a catalyst carrier, amino acid and protein, precipitant and deodorant.
