Product Description
Ceramic-grade zinc oxide is divided into two major categories: standard direct-process zinc oxide and calcined zinc oxide. It serves as a core raw material for ceramic glazes, frits, and colorants. By providing fluxing, opacifying, color-adjusting, and thermal expansion coefficient-balancing properties, it is widely used in the wall and floor tile, sanitaryware, artistic ceramics, mosaic, glass, and enamel industries. It appears as a fine white powder, free of black specks or impurities and without caking; it is insoluble in water but soluble in acidic and alkaline solutions. It exhibits strong fluxing properties at high temperatures and good thermal stability, and can form zinc-aluminum spinel with silicon and aluminum to achieve a milky white effect.
