The most widely used and best-known fine ceramic material. Good mechanical strength, electrical insulation, high-frequency loss, thermal conductivity, and resistance to heat, wear and corrosion. Sapphire is single-crystal alumina.
Silicon nitride is optimal for engine parts due to its toughness at high temperatures, superior thermal shock resistance, light weight and corrosion resistance.
Silicon carbide is the most corrosion-resistant ceramic, and is used in mechanical seals and pump parts. Strength is maintained even at extreme temperatures of up to 1400℃.
Sapphire is single-crystal alumina, a transparent material with excellent chemical stability and valuable mechanical, thermal and optical properties. Its material properties are vastly superior to glass, quartz and other mass-produced transparent materials.
The strongest and toughest of all fine ceramic materials, it is used to make scissors and knives which products once considered impossible to make from ceramic. Single-crystal zirconia is also prized as a jewel, as its refractive index creates a diamond-like-brightness.
An extremely lightweight material with low thermal expansion and excellent strength, rigidity and thermal shock resistance.
Its excellent plasma resistance is ideal for applications in semiconductor processing equipment, where particle contamination must be avoided. It contributes to productivity improvement due by reducing equipment maintenance requirements.
With its properties of electrical insulation and excellent thermal conductivity, Aluminum Nitride is ideal for applications where heat dissipation is required. In addition, since it offers a coefficient of thermal expansion (CTE) near that of silicon, and excellent plasma resistance, it is used for semiconductor processing equipment components.
Compound materials composed mainly of TiC or TiN and NbC, with metals such as Co, Ni or Mo. With excellent wear resistance, cermet has less adhesion to metal and is widely used for cutting tools, wear-resistant tools in electronics manufacturing and sliding parts. It can also be brazed with metal.
Excellent heat and thermal shock resistance, and particularly good creep resistance. Its thermal expansion index approximates that of a silicon semiconductor chip.
Superior electrical and mechanical properties with good mechanical machining performance.
Featuring low microwave loss, excellent insulation at high temperatures, and a smooth surface, forsterite is ideal for use in electron tube parts and circuit substrates. Due to its high coefficient of thermal expansion, it bonds easily with metals and glass.
