Performance: The product is white powder, has the density of 5.606 and the melting point of 1975º C, and is amphoteric oxide insoluble in water or ethanol and soluble in acid/base solution.
It can reduce the expansion coefficient of glaze and increase the thermal stability of products, and has good high heat vibration and mechanical vibration effect during the production of ceramic products.
It has big specific surface area and strong hiding power, commendably overcomes the influence of the color of base material on the surface color of ceramic products, and can increase glaze gloss and elasticity.
It is mainly used as flux, opacifier and crystallizing agent for making cerulean blue glaze, ceramic pigment, etc.
When the product is used as raw material of colored glaze, its low iron content makes ceramic products have little color aberration and good glossiness.
Application: The product is mainly used as flux, opacifier and crystallizing agent for making cerulean blue glaze, ceramic pigment, etc.
Packing: Polypropylene woven bags or kraft paper bags with a plastic film liner, 25 kg in net weight each
