FAQ
A1. Ceramics are non-metallic, inorganic materials that are typically composed of a combination of metallic and non-metallic elements. Alumina is a type of ceramic oxide, specifically an oxide of aluminum. It is widely used in various applications due to its excellent mechanical, thermal, and electrical properties.
A2. Because of their excellent chemical stability, alumina industrial ceramic rods are used widely in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings and valves. Alumina industrial ceramic rods are used in the manufacture of textile wear parts and knives. This is due to their extreme hardness and wear resistance.
A3. Alumina industrial ceramic rods is a very hard ceramic that is excellent at resisting abrasion and is ideal for wear-resistant inserts or products.
