FAQ

Q1. What is the difference between ceramic and alumina?

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.

Q2. What is alumina ceramic rods used for?

A2. Because of their excellent chemical stability, alumina ceramic rods are used widely in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings and valves. Alumina ceramic rods are used in the manufacture of textile wear parts and knives. This is due to their extreme hardness and wear resistance.

Q3. Is alumina ceramic rods hard?

A3. Alumina ceramic rods is a very hard ceramic that is excellent at resisting abrasion and is ideal for wear-resistant inserts or products.
