Ceramic Block Wear Abrasion and High Heat Temperature Resistant Alumina Zirconia Ceramic Blocks
The properties of ceramic blocks
· Flexural strength · Chemical resistance · Electrical insulation · Corrosion resistance · Dielectric strength
· Wear resistance · Temperature resistance · Thermal conductivity · High voltage · Hardness...
High heat and temperature resistant
The high temperature ceramic blocks have a excellent high heat temperature resistant ability. heat resisting ceramic block can be used under 2200 ℃ high temperature environment.Coefficient of thermal expansion up to 13* 10∧6 from 20°C- 1000°C. up to 2800°C Melting point.
Wear and hardness and abrasion resistant
The ceramic wear blocks is better wear and abrasion resistant property than metal. The ceramic hardness (mohs)up to 9, HRA 80-90. Ceramic hardness is not second only to diamond, but far beyond the wear resistance of steel and stainless steel.
Ceramic wear block made of technical ceramics with wear abrasion high heat temperature resistance ceramic blocks property.
Ceramic block or plates ,sheet including higher density, bending/better compressive strength, greater flexibility, high dielectric strength and dimensional stability and non-flammable resistance and temperature.
