Note: We can supply different size products of
si3n4 ceramic powder according to client's requirements.
Si3N4 powder has excellent thermal conductivity, thermal expansion coefficient, good insulation, light transmittance, high temperature and corrosion resistance.
Application of si3n4 ceramic powder:
1. Manufacture of precision structural ceramic devices: balls and rollers, sliding bearings, sleeves, valves, and wear-resistant, high-temperature, corrosion-resistant requirements for rolling bearings used in industries such as metallurgy, chemical, machinery, aerospace, aerospace and energy. Structural device.
2. Surface treatment of metals and other materials: such as molds, cutting tools, turbine blade turbine rotors and cylinder inner wall coatings.
3. Preparation of high performance composite materials: such as metal, ceramic and graphite-based composite materials, rubber, plastics, coatings, adhesives and other polymer-based composite materials.
4. Application of nano-silicon nitride in high wear-resistant rubber: NSN series rubber super wear-resistant enhancer with nano-scale silicon nitride (average particle size 20 nm) has achieved amazing application results.
5. Metal surface wear-resistant composite plating application: silicon nitride has high hardness and small sliding friction coefficient. Its mechanical properties are high compared to other ceramic materials, such as molds, cutting tools, steam turbine blades, turbine rotors and cylinder inner wall coatings.
6. Nano-silicon nitride in the special absorption of human body infrared textile applications: silicon-based nano-powder is nylon, polyester enhanced conductivity. Nano-silicon nitride has the absorption rate of the infrared absorption band of the human body above 97%, which is the best absorption infrared ultra-fine textile additive.
7. It is mainly used for stripping between silicon melt and quartz crucible when polycrystalline silicon and single crystal silicon are smelted.
8. Application of nano-silicon nitride in other industrial fields: high-performance wear-resistant, high-temperature rubber seals and rubber tires, application in anti-corrosion refractory coatings, application in high-temperature insulating electronic materials, application in inorganic ceramic lubricating oils The application of metal surface ceramic wear-resistant composite plating, the application in structural ceramics and inorganic composite materials, and the application in epoxy resin.
SEM & XRD of si3n4 ceramic powder:
Storage conditions:
si3n4 ceramic powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
