Characteristics and Effects:

1. Due to low expansion coefficient, it has good effects of high heat vibration and mechanical vibration during the production of ceramic products.

2. It has large specific surface area and strong covering power, avoiding the influence of base material color to surface color of ceramic products.

3. It contains little Fe, makes ceramic products have little aberration when used as colored glaze raw material, and has good glossiness.

Application:

Ceramic grade zinc oxide is used for developing ceramic pigment, producing ceramic glaze and burning frit. It also can be used for production of high-end glass products.

Packaging and Transport:

1. Inner plastic and outer braiding double-layer packaging.

2. Standard bag weight: 25kg.

3. Package according to customer demands.

4. Guard against damp during transport and storage.
