Resistor Ceramic 95% 99% Alumina Ceramic Rod

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 ceramic is a kind of material based on alumina (Al2O3), which is used in thick film integrated circuit. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It needs to be noted that ultrasonic cleaning is needed. Because of its superior performance, it has been widely used in modern society, meeting the needs of daily use and special performance.

People usually call the ceramics with 75% dry Al2O3 content as high alumina ceramics. Alumina ceramic is one of the most widely used structural ceramics. It is more economical and practical to use 95% alumina ceramic in general situations. Only 99%~99.9% alumina ceramic is used for occasions with high performance requirements.

Because it has excellent electrical performance at high frequency, its dielectric loss is small, its volume negative rate is large, its strength is high, its hardness is large, its linear expansion coefficient is small, and its wear resistance and heat resistance are also good.

95% alumina ceramics have good thermal shock resistance, and can withstand the test of high temperature and rapid cooling without damage.

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
