INNOVACERA is good at yttria stabilized zirconia. Unlike other ceramic materials, zirconia is a material with very high resistance to crack propagation. Zirconium oxide ceramics also have very high thermal expansion and are therefore often the material of choice for joining ceramic and steel. Features: > high fracture toughness > thermal expansion similar to cast iron > extremely high bending strength and tensile strength > high resistance to wear and to corrosion > low thermal conductivity Ceramic material composition: . TTZ: Magnesia partially stabilized Zirconia (ZrO2) · YTZP: Yttria partially stabilized Zirconia (ZrO2) · ZDY: Yttria fully stabilized Zirconia (ZrO2)

Aluminum nitride ceramics have excellent electrical and thermal properties, and are considered to be the most promising high thermal conductivity ceramic substrate materials. In order to seal the package structure, mount components and connect input and output terminals, the surface and interior of the aluminum nitride ceramic substrate need to be metallized. The reliability and performance of ceramic surface metallization have an important impact on the application of ceramic substrates, and firm bonding strength and excellent air tightness are the most basic requirements. Considering the heat dissipation of the substrate, it is also required to have high thermal conductivity at the interface between the metal and the ceramic. The metallization methods on the surface of aluminum nitride ceramics include: thin film method, thick film method, high melting point metallization method, electroless plating method, direct copper cladding method (DBC), etc.
