High Heat Rod Ceramic Rod Wear Insulator High Temperature Resistant Alumina Zirconia Ceramic Rods

The properties of alumina/ zirconia ceramics

· Flexural strength	· Chemical resistance	· Electrical insulation	· Corrosion resistance	· Dielectric strength
· Wear resistance	· Temperature resistance	· Thermal conductivity	· High voltage	· Hardness...

Ceramic rod has the characteristics of wear insulator high temperature resistant with the excellent ceramics.

High heat and temperature resistant
The ceramic have a excellent high heat temperature resistant ability. Ceramic can be used under 2200 ℃ high temperature environment.Coefficient of thermal expansion up to 13* 10^∧⁶from 20°C -1000°C. up to 2800°C Melting point.

Wear and hardness resistant
The ceramic 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.

High voltage and Insulator
High frequency insulating ceramics have small dielectric constant, low dielectric loss, high mechanical strength, high dielectric strength, insulation resistance and thermal conductivity.Dielectric constant up to 10; Electrical resistivity up to 10^∧14 Ohm.cm at 20°C ;Dielectric strength up to 20 kV/mm...
