Silicon Nitride Ceramics Powder

silicon nitride ceramics


Silicon nitride ceramic is an inorganic material ceramic that does not shrink during sintering. The strength of silicon nitride is very high, especially hot-pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density, high temperature resistance and other properties.
High temperature resistance, the strength can be maintained to a high temperature of 1200 without decreasing, and will not melt into a molten body after being heated, and will not decompose until 1900 It has amazing chemical corrosion resistance, and can withstand almost all inorganic acids and less than 30% caustic soda solution, as well as many organic acids; It is also a high-performance electrical insulating material.
Si3N4 can be used to manufacture ball bearings by virtue of its light weight and high rigidity. It has higher accuracy than metal bearings, generates less heat, and can operate in higher temperatures and corrosive media. The steam nozzle made of S ceramic has wear resistance, heat resistance and other characteristics, and it will not be obviously damaged after being used in 650 boiler for several months.

ferro silicon nitride powder is applicable to stainless steel smelting, special alloy steel smelting, oriented silicon steel smelting and other casting industries.

As a new type of refractory material, it is applied in the metallurgical field, such as metallurgical furnace body, furnace mouth seal, ironmaking furnace outlet, iron hook amorphous material and nitrogen additive in the steelmaking industry.
Silicon nitride material can be used as abrasive material for abrasive tool manufacturing, and can also be used in chemical fields such as acid resistance, alkali resistance and corrosion resistance.
In terms of steelmaking, granular ferro silicon nitride is mainly used in the production of oriented silicon steel at the initial stage, and it can stably supplement a certain amount of nitrogen for molten steel.

aluminium nitride ceramics


The color of high thermal conductivity aluminum nitride ceramic sheet is gray white, and the surface is smooth. It can be made into any shape or size for easy use and installation.
Aluminum nitride ceramic heat sink has a very high thermal conductivity, which is 7-10 times higher than that of aluminum oxide ceramic, and can reach 180W. Its electrical insulation performance is quite stable, its dielectric constant and dielectric loss are low, and it can withstand the ultra-high temperature of 1800 degrees Celsius without affecting the working performance of the product
With the rapid development of electronic equipment, the demand for electronic or auxiliary products is also increasing, and the application rate of high thermal conductivity aluminum nitride ceramic heat sink as a matrix or packaging material is also increasing in the market.

Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys.

Metallic silicon is a product made of quartz and coke smelted in an electric furnace. The content of the main component silicon is about 98%, and the other impurities are iron, aluminum, calcium, etc.

In industry, silicon metal is usually produced by reducing silicon dioxide by carbon in an electric furnace. Chemical reaction equation: the purity of silicon prepared by SiO2+2C Si+2CO is 97 98%, which is called metallic silicon. Then it is melted and recrystallized, and impurities are removed with acid to obtain metallic silicon with purity of 99.7~99.8%.
Metal silicon particles: 1-200mm

silicon metal should be used to produce organic silicon, produce high-purity semiconductor materials and prepare alloys with special purposes.

(1) Production of silicone rubber, silicone resin, silicone oil and other silicone.

(2) Manufacture high-purity semiconductors.

(3) Prepare alloy.

(4) It is an excellent antioxidant in refractory and powder metallurgy industries.

Our company can provide various specifications and models of metal silicon blocks, particles and powders according to customer requirements.
