surface production and the burn melt block. This kind of zinc oxide is also available in top-grade glass
production. Characteristic and function: 1.Yongchang Zinc Industry brand zinc oxide's coefficient of expansion is low.It has good effect for high
fever vibration and the mechanical vibrations in the ceramic production process. 2. The specific surface area is big and with hiding power, having resolved the bottom material influence
to the surface colour. 3. There is less element content of iron, when used as the raw materials of color glaze, it can make little
colour difference.
It has very good smoothness.
