The advantages of calcined zinc oxide include:

After calcination, the water-soluble matter, volatile matter and metal element are greatly reduced, making the material quite stable in the production of ceramic products, and greatly reducing the porosity of the glazed surface.

The physical properties of calcined zinc oxide are very similar to those of other ceramic raw materials, and it is easier to use and manipulate in the production process.

The bulk density of calcined zinc oxide is above 0.5g/cm3, and that of ordinary zinc oxide is below 0.2g/cm3.

Calcined zinc oxide has a strong fluxing effect in ceramic colored glazes, which can reduce the expansion coefficient of the glaze, prevent cracking, and make the glaze surface have good elasticity and luster.

The calcined zinc oxide used in ceramics has uniform and accurate color development, rich and gorgeous color shadows.

Calcined zinc oxide can play a primary refining role in ceramics, removing organic matter and carbonates in natural raw materials.

Therefore, calcined zinc oxide has many advantages in ceramic production, which can improve the quality and stability of products.
