heat isolated customized Zirconia Ceramic board sheet
Reputation depends on quality, quality comes from Hard!
Zirocnia Ceramics:
Zirconia has high hardness, Hv = 18GPa ～ 21? Gpa, HRA = 91 ～ 93, second only to a few superhard materials such as diamond, cubic BN, B4C, etc., the friction coefficient is small (0.1), and has self-lubricating , Similar to the oiled metal surface (0.1-0.2)
Silicon Nitride is a covalent compound, so the atoms are combined with strong covalent bonds, so it has a high hardness and melting point
Can be used as raw material for high temperature ceramics
The energy dissipation ability of any material can be easily evaluated by the hardness and elastic modulus of the material. At the same time, for materials with known energy dissipation ability, the elastic modulus can be estimated from the hardness value. Therefore, in the selection of materials or reliable In terms of performance evaluation, many material properties, such as brittleness, local energy dissipation ability, elastic recovery ability, resistance characteristics, guided wave rate, etc., can be simply estimated and compared by hardness and elastic modulus. This is for material design and structural design. And material performance prediction are of great significance
The ceramic material is a combination of polycrystals. The junction between the same-component grains with different crystal directions is called the grain boundary, and the junction between the good-component grains is called the phase boundary. Both are important for the microstructure. The research object studies the material at the grain boundary [structure characteristics, called the grain boundary structure
