Description

Alumina Ceramic Rods / Aluminum Oxide Insulation Rods for Battery

1. Description:

Alumina, or aluminum oxide Al2O3, with a molecular weight of 102, is the major source of aluminium in nature. Al2O3 has very high melting point, which is 2,072 °C and it is extremely hard. Alumina ceramic is the most common technical ceramic material and relatively traditional material. High purity aluminum oxide ceramics as a fine ceramic material is widely used in a lot of industries. This material has superb performances in electrical insulation, high thermal conductivity, high chemical resistance, good wear resistance and low thermal expansion.

Feature Advantages:

1) High hardness and high density

2) Low thermal conductivity

3) Chemical inertness

4) Good wear resistance

5) Lower medium spoilage

6) Stiffness texture
