What role does Zinc oxide for ceramics play in ceramics?

1) Zinc oxide for ceramics can improve the hardness of ceramics in the production of ceramics;

Traditional ceramics are extremely fragile products. With the improvement of production technology, the addition of Zinc oxide for ceramics to ceramics has increased the hardness by nearly three times on the original basis. This kind of ceramics with certain hardness is on the market. It is more popular.

2) Zinc oxide for ceramics can increase the brightness of ceramics;

In the hand-made pottery period, people used many methods to increase the brightness of the finished pottery, but the effect was not obvious. Later, with the addition of Zinc oxide for ceramics, the high gloss of the finished ceramics has been greatly improved, and the value of ceramics collection has been improved.

3) Zinc oxide for ceramics can adjust the color of ceramics; if you want to have bright and uniform ceramic products, zinc oxide additives are essential in processing and production.

4) Zinc oxide for ceramics can evenly glaze in the ceramic industry;

Glazing is a very technical work. Many times a ceramic product that is about to be completed may be destroyed in the glazing stage. After adding Zinc oxide for ceramics, the color glazing becomes less terrible.
