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.All the above big-size ceramic sheets can be cut to specific dimensions per customers' requirements.

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.)

Our alumina substrate has well-balanced properties of insulation, thermal conductivity and breaking strength. Moreover, one of the unique properties is its surface roughness. We can provide the ceramic substrate which is excellent in adhesion with a thin film and thick film metalization due to fine particles.

Property for 99.5%&99.6% Al2O3 ceramic substrate:

A. Good smoothness / flatness with less porosity.

B. Excellent in adhesion with thin film and thick film materials.

C. Less variance in outline, plate thickness, slit pitch, etc.

D. Minimal warpage, bending, and undulation.

E. Physical and chemical properties are stable even under a hot environment. Excellent in thermal shock resistance. High thermal conductivity and coefficient of thermal expansion similar to that of silicon.

F. Superior mechanical strength. Products with higher mechanical strength are also in our lineup.

G. Excellent resistance against oil and chemical.

H. Excellent in insulation properties, high dielectric breakdown voltage, high surface resistivity / volume resistivity, and small dielectric constant.

I. Stable breaking strength, and less variance in shape or dimensions.

J. The high reflective substrate, especially suitable for optical applications such as LED, is also available.
