Beryllia (BeO) is a toxic compound of beryllium metal and oxygen. Beryllia's combination of high electrical-resistivity and high thermal-conductivity is useful for electronic substrates. Beryllia ceramics provide a thermal conductivity that is only second to diamond among electrically-insulating materials. Beryllia provides a thermal coefficient of expansion (TCE) intermediate to gallium arsenide and refractory metal composites, as well as low dielectric constant (6.7) and low loss index (0.0012 at 1 MHz), permitting improved circuit performance at high frequencies. Unlike nitrides, which will decompose to their oxide equivalent, beryllia is very stable under oxidizing and reducing high-humidity environments. Products & Services
Industrial ceramic materials are non-metallic, inorganic compounds that include oxides, carbides, or nitrides. They have high melting points, low wear resistance, and a wide range of electrical properties.
Ceramic tube and ceramic rod products are suitable for use in applications requiring high temperature strength, erosion resistance, electrical or thermal insulation, and other specialized characteristics.
Oxide ceramics include alumina, zirconia, silica, aluminum silicate, magnesia and other metal oxide based materials.
Ceramic powders and precursors contain oxides, carbides, nitrides, carbon, and other non-metals. They are usually micron or mesh-size in distribution. Ceramic powders, sol-gel solutions and precursors are fabricated through atomization, crushing, milling, precipitation, and other chemical processes.
Dielectric ceramics and substrates are electrical insulators with dielectric strength, dielectric constant and loss tangent values tailored for specific device applications.
