High Temperature 95%/99% Al2O3 Alumina Ceramic Lamp Holder Manufacturers

Alumina, or aluminum oxide, with a molecular weight of 102, is the major source of aluminum in nature. Alumina ceramic is the common technical ceramic material and a relatively traditional material. High purity alumina ceramics as a fine ceramic material is widely used in a lot of industries. 

Alumina, also known as Aluminum Oxide, is the most cost effective and widely used material in the family of engineering ceramics. Alumina has excellent insulating property, heat resistance and wear resistance. Because of its well-balanced comprehensive properties and relatively low cost, alumina is one of the most popular ceramic materials. High purity(over 99.8%) alumina is widely used in semiconductor equipment due to its great resistance to corrosion and plasma.

Main Features:

1. High hardness

2. High heat resistance

3. Good wear resistance

4. High electrical resistivity

5. High corrosion resistance

Technical Parameters

Production process

1. Grind and crush the raw materials to be slurry or powder

2. se-different method to making the slurry or powder into semi-finished products

3. Put the semi-finished products into the kiln for dewaxing and sintering;

4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.

5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
