Alumina Ceramic:
Alumina ceramics are classified into high-purity type and ordinary type.
The high-purity alumina ceramics have a Al2O3 content of 99.9% or more. Since the sintering temperature is as high as 1650-1990 ° C and the transmission wavelength is 1 to 6 μm, the molten glass is generally used to replace the platinum crucible,it can be used as an integrated circuit substrate and high-frequency insulation material in the electronics industry.
Alumina ceramics is a versatile ceramic. Because of its superior performance, it has been widely used in modern society, satisfying the needs of daily use and special performance.
Alumina ceramics are ceramic materials based on alumina (Al2O3) 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.
99.6% Alumina Application:
A.LED packages, Substrate for chip resistors, HIC substrates for heat dissipation, Power modules, FAX substrates for thermal printer head
B.Various processing is available (thin film metalization, thick film metalization, glaze, etc.)
