Product Overview
Alumina ceramics have many excellent properties, so they are widely
used in the world. Alumina ceramics have a Vickers hardness of
15GPa, a density of about 3.75g/cm3, a compressive strength of
about 2100MPa, a flexural strength of 300Mpa, a volume resistance
of 1014Ω·m, an expansion coefficient similar to that of metals, and
good chemical stability.
Yixing Weite Ceramics Co., Ltd. is located in Dingshu Town, Yixing, the hometown of Zisha pot. It is a professional manufacturer of precision alumina and silicon nitride ceramic products integrating scientific and technological development, production and sales. Main products: 95, 99 alumina ceramics, silicon nitride ceramic products, ceramic liners, welding ceramics, electrical ceramics, industrial ceramics, etc. Welding ceramics: argon arc welding ceramic nozzle, air plasma protective cover, shunt, stud welding porcelain ring, ceramic gasket for submerged arc welding. Electronic ceramics: ceramic ignition head for high, medium and low voltage igniters, porcelain base for various electrical connectors. Industrial ceramics: various mechanical ceramic parts, textile ceramics, special insulating ceramic ring for polysilicon reduction furnace, etc. The company covers an area of 15 mu, with two standardized workshops. There are one kiln for high, medium and low temperature, 58 sets of presses and lathes. A set of isostatic pressure equipment.
High-frequency insulating ceramics, also known as device ceramics, are used in electronic equipment to install, fix, and protect components, as insulating supports for current-carrying conductors, and as ceramics for various integrated circuit substrates. Small dielectric constant, low dielectric loss, high mechanical strength, and high dielectric strength, insulation resistance and thermal conductivity. Commonly used high-frequency insulating ceramics include high-alumina porcelain and talc porcelain.

Product advantages
• Size and thermal stability
• High performance features
• Hydrolysis resistance
• Self-lubricating performance
• Extended service life
Alumina ceramic material has good insulation, otherwise, stainless, strong and not easy to damage, and has the same excellent properties as other organic materials and metal materials. The production process of alumina ceramics includes five steps: calcination, batching, fine grinding, shaping and sintering.
