Калцинисани цинков оксид

Calcined zinc oxide is an oxide of zinc. After high-temperature calcination, zinc oxide appears light yellow with a melting point of 1975 ℃. It is insoluble in water but soluble in acids and strong bases. It is obtained by burning zinc or roasting sphalerite (zinc sulfide), and is a heavy calcined zinc oxide that has been processed and calcined at high temperatures. The calcined zinc oxide we produce has a high specific gravity and good fluidity. The glaze produced with it has low shrinkage and is less prone to pinholes and cracks on the glaze surface. Calcined zinc oxide is an important ceramic chemical flux raw material, especially used in building ceramic wall and floor tile glazes, low-temperature ceramic glazes, and ceramic pigments. It is also widely used in artistic ceramic glazes. Our calcined zinc oxide has a strong melting aid effect in glazes, which can reduce the expansion coefficient of glazes, improve the thermal stability of products, and increase the gloss and whiteness of glazes, as well as enhance their elasticity. Expanding the melting range can increase the luster of the glaze color. However, use with caution in black glazes containing chromium. Due to its strong fluxing effect, calcined zinc oxide can be used as a flux, mineralizer, and glaze coloring carrier for ceramic pigments, and as the main raw material in the brown ceramic pigment series. Calcined zinc oxide can also be used as a glass additive. Zinc oxide with added aluminum, gallium, and nitrogen has a transparency of 90% and can be used as a glass coating, allowing visible light to pass through while reflecting infrared radiation. Coatings can be applied to the inside or outside of window glass to achieve insulation or thermal insulation effects.
