Good Thermal Shock Conductivity Si3n4 ceramic Substrate Plate

Si3N4 ceramic is an important structural material. It is a kind of super-hard material. It is lubricious and wear-resistant. It does not react with other inorganic acids except hydrofluoric acid. It has strong corrosion resistance and resistance at high temperature. Oxidation. Moreover, it can withstand cold and hot shock. It is heated to above 1,000 °C in air, and is rapidly cooled and heated rapidly without cracking. It is because of the excellent characteristics of Si3N4 ceramics that people often use it to manufacture bearings. Mechanical components such as gas turbine blades, mechanical seal rings, permanent molds, etc. If the silicon nitride ceramics with high temperature resistance and heat transfer resistance are not used to manufacture the heating surface of the engine components, the quality of the diesel engine can be improved, the fuel can be saved, and the thermal silicon nitride ceramic thermal conductivity.

Silicon Nitride Ceramic Thermal Conductivity

Silicon nitride usually offers comparatively low thermal conductivity compared to silicon carbide or aluminium nitride owing to its unique chemical composition and crystal structure. These fine ceramic grains typically grow faster in a lengthwise plane, resulting in an interlocking needle-like structure that exhibits anisotropic thermal properties. This represents significantly reduced thermal conductivity in severe temperatures. The thermal properties of silicon nitride are also unique due to the material’s high density composition, which displays a reduced magnitude of change at elevated temperatures.

Silicon Nitride Ceramic 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.
