Alumina tiles
■ Good smoothness / flatness with less porosity. Excellent in adhesion with thin film and thick film materials.
Alumina tiles with Less variance in outline, plate thickness, slit pitch, etc.
■ Minimal warpage, bending, and undulation.
■ 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.
■ Superior mechanical strength. Products with higher mechanical strength are also in our lineup.
■ Excellent resistance against oil and chemical.
■ Excellent in insulation properties, high dielectric breakdown voltage, high surface resistivity / volume resistivity, and small dielectric constant.
■ Stable breaking strength, and less variance in shape or dimensions.
■ The high reflective substrate, especially suitable for optical applications such as LED, is also available.
Application
Ceramic block can be used for a device or equipment in the special environment such as Power isolation, high temperature protection, durable wear, high and low temperature impact etc...and for the different device should be requiry different ceramic block shapes, like: some device need the round sheet be machining 8 hole to fasten to the box.
Other type of ceramic sheet/ plate/ substrate/ piece/ blank
