Zirconium Disilicide Powder (ZrSi2)

Zirconium disilicide has the characteristics of high melting point, high hardness, and excellent thermal conductivity. It usually exists in the form of gray powder, insoluble in water, but soluble in hydrochloric acid and hydrofluoric acid. As a ceramic material, zirconium disilicate has a wide range of applications in manufacturing fine ceramic raw materials, crucibles for semiconductor film production, refractory materials, ceramics, and enamel. In addition, it can also be used to manufacture grinding and grinding beads, shading materials, and other silicified chemicals.
