Alumina industrial ceramic plate is a material widely used in various fields with various characteristics and advantages.
1. Good thermal conductivity
Alumina ceramics can quickly conduct heat in high-temperature environments and reduce temperature gradients, thereby improving equipment stability and efficiency.
2. High insulation
The resistivity of alumina ceramics is as high as 10^14Ω·cm, which can can ensure the safe operation of electrical equipment and lines.
3. High hardness
Alumina ceramics have very high hardness, with a Mohs hardness of about 8-9, second only to diamond, and its wear resistance far exceeds that of wear-resistant steel and stainless steel.
4. High melting point
The melting point of alumina ceramics is as high as 2050ºC, which enables it to maintain stable physical and chemical properties in high temperature environments.
5. Excellent corrosion resistance
Alumina ceramics have good corrosion resistance to most acids, alkalis, salts and other chemical substances, and can withstand chemical corrosion in various complex environments.
Application Examples
1. Ceramic substrates
Alumina ceramics have the advantages of high thermal conductivity, good heat resistance, high mechanical strength, and low thermal expansion coefficient. They are commonly used substrate materials for power semiconductor device packaging. Alumina ceramic substrates are currently the most widely used ceramic substrates.
2. Ceramic thermally conductive pads
Alumina ceramic thermally conductive pads are mainly used for heat transfer and electrical isolation between power devices and radiators. The heat dissipation path is divided into two parts:
(1) Power device (heat source) → thermal grease → ceramic gasket → thermal grease → radiator (heat transfer is mainly conduction);
(2) Radiator → ambient air (heat transfer is mainly convection).
3. Ceramic insulation sheets
Alumina ceramic insulation sheets can reduce current loss and signal interference, and improve the transmission efficiency and stability of the system. It is widely used in the fields of electronics, electrical and machinery, providing reliable insulation protection for related equipment and systems.
Jinghui Ceramic has been focusing on the manufacture of industrial ceramic plates for the last 15 years with carefully selected materials, optimized production equipment and strict quality control all link to guarantee the high performance, ideal consistency and cost competition.
