Bismuth titanate ceramics have a very high Curie temperature and operating temperatures of up to 550°C. The materials exhibit low dielectric constant, low dielectric loss and properties stable up to very high temperatures. Bismuth titanate ceramics are used in high temperature applications such as pressure sensors and accelerometers. Bismuth titanate belongs to the group of sillenite structure-based ceramics (Bi12MO20 where M=Si, Ge, Ti). Products & Services
Piezoelectric ceramics produce an electrical charge when a load is applied and deformation occurs. Piezoelectric ceramics can also produce force or deformation when an electrical charge is applied.
Dielectric ceramics and substrates are electrical insulators with dielectric strength, dielectric constant and loss tangent values tailored for specific device applications.
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.
Electroceramics are ceramic materials that have been specially formulated for specific electrical, electro-magnetic, or optical properties. They include dielectric ceramics, electrostrictive ceramics, ferrite ceramics, garnets (ferromagnets), and piezoelectric ceramics.
Lead, tin and low melting alloys (white metals) are non-ferrous alloys used in the manufacture of solder, semiconductor, battery and decorative products.
