Alumina ceramics’ main properties
Alumina ceramics, a ceramic material containing alumina (Al2O3) is used for thick-film integrated circuits. Alumina ceramics exhibit high conductivity, mechanical strength, resistance to high temperatures and good conductivity. Ultrasonic cleaning may be required. Alumina ceramics can be used in many different ways. Alumina ceramics are becoming more popular in modern society because of their superior performance.
Alumina industrial ceramics offer excellent insulation, wear resistance and high temperature resistance. They are popularly used in many industries, including electronics, chemical, refractory, as well as machinery and electronics. So what are the various uses of alumina, you ask?
The main applications of alumina in industrial ceramics
1. The main components in ruby and sapphire’s are alumina industrial clays. These will display different colors due to other impurities. Ruby has chromium dioxide, and is red. Sapphire has iron oxide (and is also blue), and sapphire has titanium oxide (and is also blue).
2. The content of alumina industrial clays, which is the major component of bauxite of biauxite, is the highest.
3. Aluminum is resistant to corrosion in the atmosphere because it is made from industrial ceramics. Pure aluminum is very easy for oxygen to react with, creating a thin aluminum oxide film in order to protect the aluminum surface.
This layer of alumina ceramic film can help prevent further aluminum oxidization. Anodizing is a process that increases the thickness of oxide films.
4. Aluminum is a good conductor and heat conductor. Because of its high hardness and adaptability, carborundum is the crystal form. It is ideal for cutting tools and abrasive materials.
