Alumina ceramics is a ceramic material with alumina (Al2O3) as the main body, used for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramics is a kind of ceramics with a wide range of uses. Because of its superior performance, it has become more and more widely used in modern society to meet the needs of daily use and special performance.
The properties of alumina industrial ceramics are wear resistance, high temperature resistance, acid and alkali corrosion resistance, and good insulation. Because their raw materials are relatively cheap and easy to obtain, they are widely used in machinery, electronics, chemical, refractory and many other industries. So what are the uses of alumina?
1. The main components of ruby and sapphire are alumina industrial ceramics, which will show different colors because of other impurities. Ruby contains chromium oxide and is red, while sapphire contains iron oxide and titanium oxide and is blue.
2. Among the main component bauxite of bauxite, the content of alumina industrial ceramics is the highest.
3. Alumina industrial ceramics is the reason why metal aluminum is not easily corroded in the air. Pure metal aluminum is extremely easy to react with oxygen in the air, forming a thin aluminum oxide industrial ceramic film to cover the aluminum surface exposed to the air.
This layer of alumina industrial ceramic film can prevent aluminum from being oxidized further. The thickness of this oxide film can be effectively enhanced by a process called anodizing.
4. Aluminum is a good conductor of electricity and heat. The crystal form of aluminum is carborundum because of its high hardness, which is suitable for abrasive materials and cutting tools.
