Silicon Nitride Ceramic:

Silicon nitride ceramics have high strength and good toughness, the compressive strength can reach 2500MPa, and the fracture toughness can reach 8MPam1/2. The thermal expansion coefficient of Zirconia Ceramic Pin this material is small, which is (2.5~3.5×10-6/℃). Zirconium quartz and mullite are similar; silicon nitride has good thermal conductivity, the thermal conductivity is between 23~25W/m·K, has good thermal shock resistance, and is an excellent heat-resistant ceramic.
Silicon nitride has high hardness, and its microhardness is 16~18GPa. Silicon nitride has low friction coefficient and good self-lubricating ability. The friction coefficient is between 0.02 and 0.35, which is equivalent to the metal surface of oil. Due to its high hardness and small friction coefficient, it is an important tool material and mold material. High-speed heavy cutting, suitable for cutting nickel-based and titanium-based alloys. Due to its low coefficient of friction and self-lubricating ability, it is an excellent bearing material.
Silicon nitride has high resistivity (room temperature 1.1×1012Ω·m), high dielectric constant (ε=9.4), Ceramic Flange and low dielectric loss, so it is an excellent dielectric ceramic, equivalent to corundum, and can be used as a circuit base Chips, high temperature insulators, capacitors and radar antennas, etc.
Silicon nitride has excellent chemical stability, except for hydrofluoric acid, it is resistant to corrosion by all inorganic acids and some lyes, molten alkalis and salts. Silicon nitride has excellent oxidation resistance, because a dense silicon dioxide protective layer is formed on the surface, and its oxidation resistance is comparable to that of silicon carbide.

properties:

High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
