Aluminum Oxide ceramic (Al2O3(ceramic))

Alumina substrates are mainly used in the electronics industry, such as high-frequency RF and microwave devices, power semiconductors, laser diodes, optoelectronic devices, etc. In addition, it is also widely used in thermal management solutions, where it is used as a heat sink and electrical insulator due to its good thermal conductivity and electrical insulation. In the power and automotive industries, alumina is also an important material for power electronics and sensors.

• High melting point and thermal stability: Alumina has a melting point of up to 2072°C, making it stable in high-temperature environments.
• Good electrical insulation: Alumina has high resistivity and low dielectric losses, making it excellent in electronics.
• Excellent thermal conductivity: Alumina has better thermal conductivity than most ceramic materials, making it an ideal thermal management solution.
• Good chemical stability: Alumina is resistant to most acids and bases, making it stable in harsh environments.
• High hardness and abrasion resistance: Alumina has high hardness and excellent abrasion resistance, which makes it excellent durability in mechanical and industrial applications.
