Alumina Ceramics:
Zinc oxide is an important raw material for ceramic chemical fluxes, especially in building ceramic wall tile glaze and low-temperature porcelain. It is also widely used in artistic ceramic glaze.
Zinc oxide has a strong fluxing effect in the glaze, which can reduce the expansion coefficient of the glaze and improve the thermal stability of the product. While expanding the melting range, it can increase the glaze of the glaze. However, it should not be used in black glaze containing chromium.
Used as flux: When zinc oxide is used as a solvent in low-temperature frit glaze, the general dosage is between 5% and 10%, and the dosage in low-temperature raw glaze is usually about 5%.
Used as an opacifier: Adding zinc oxide to the glaze containing higher A1203 can improve the opacity of the glaze. Because zinc oxide can produce zinc spinel with A1203, ZnO A1203 crystal, in zinc-containing opalescent glaze, A1203 can improve the whiteness and opacification of the glaze. SIO2 can improve the gloss of the glaze.
Used as a crystallizer: In artistic glaze crystallization, zinc oxide is an indispensable crystallizer. When the melted glaze is rapidly cooled, it forms a large crystal pattern, which is very beautiful. In crystalline glaze, the amount of zinc oxide is as high as 20-30%.
Used to make cobalt sky blue glaze: Zinc oxide is a very important flux in cobalt sky blue glaze. It can make cobalt oxide form beautiful sky blue in glaze.
Used as ceramic pigment: Due to its strong fluxing effect, zinc oxide can be used as a rib flux, mineralizer and glaze carrier for ceramic pigments.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
