Alumina Ceramic Plate
My factory looking for distributors.
Alumina ceramic plateis also called wear-resistant alumina ceramic plate, high alumina ceramic plate, wear-resistant ceramic plate, alumina ceramic patch. Alumina ceramic plate is mainly made of AL2O3 as raw material, rare metal oxide as solvent and calcined at 1700℃.
Advantages of alumina ceramic plates
1.The Alumina Ceramic Plates have been meticulously crafted to exhibit exceptional hardness and durability.
2.The Alumina Ceramic Plates offer excellent electrical insulation properties.
3.The alumina ceramic plates boast high density and rigidity.
4.Understanding the needs and preferences of our esteemed customers, we have crafted the Alumina Ceramic Plates to meet their highest standards.
5.Our Alumina Ceramic Plates are incredibly versatile, offering endless possibilities for various applications.
Application of alumina ceramic plates
The alumina ceramic plate has become the protective film of the machine. The addition of alumina ceramic plate on the machine is not only high temperature resistant, but also can effectively prevent the machine from slipping, reduce the friction and impact in the machine, keep the machine long-term production without damage, reduce maintenance, and save The production cost effectively prolongs the service life of the machine. Of course, the important point is that the alumina ceramic plate is environmentally friendly, which can effectively reduce energy consumption and is conducive to the long-term development of the industry.

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 used for?
A2. Because of their excellent chemical stability, alumina ceramics are used widely in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings and valves. Aluminum oxide ceramics 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 hard?
A3. Alumina is a very hard ceramic that is excellent at resisting abrasion and is ideal for wear-resistant inserts or products.
