Production method Of Ceramic Grade Zinc Oxide :
The ceramic grade zinc oxide is suitable for the ceramic pigment development, the ceramic glazed surface production and the burn melt block. This kind of zinc oxide is also available in top-grade glass production.
Application of Zinc Oxide :
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 color.
3. There is less element content of iron, when used as the raw materials of color glaze, it can make little color difference. It has very good smoothness.
Packing and storage Of Zinc Oxide :
This product is packed with plastic-lined and plastic-coated woven bags, 25kg per bag.
This product should be keep from breakage, moisture, pollution and contact with acid.
Product quality standards: GB/T 3185-92
