Product Description

Features & Advantages:

1) High hardness. 2) High heat resistance: high melting point and boiling point. 3) Good wear resistance: Zirconia ceramics is the preferred material for wear parts. 4) High resistivity: Zirconia is an electrical insulating material. At high temperature, it has excellent properties such as electrical conductivity. 5) Strong corrosion resistance: insoluble in water, only slightly soluble in strong acid and alkali solutions. The good chemical stability of alumina results in high corrosion resistance.

Applications:

1) Grinding media. 2) Precision mechanical parts. 3) Textile industry. 4) Used in catalyst carrier, medical treatment, refractory material. 5) Used as refractory material and heating element. 6) Cutting tool. 7) Wear-resistant tool.
