What is silicon nitride?
Silicon nitride is an essential structural ceramic product with high solidity, lubricity, and also put on resistance. It is an atomic crystal that stands up to oxidation at high temperatures. It can likewise stand up to cold as well as warm shocks. It can be heated up to greater than 1000 ℃ in air, cooled down greatly, and after that warmed smartly without breaking. It is specific due to the fact that silicon nitride porcelains have such exceptional characteristics that people commonly use it to produce bearings, generator blades, mechanical seal rings, Permanent molds, as well as other mechanical elements. Suppose silicon nitride porcelains that are resistant to heats and hard to warmth transfer are utilized to make the home heating surfaces of engine parts. In that situation, it can enhance the high quality of center extract engines and also conserve gas and thermal effectiveness. China, the USA, Japan, as well as other nations have established middle distillate engines.

The production method of silicon
nitride There are 2 production methods of silicon nitride ceramic products, particularly reaction sintering and hot pushing sintering. The response sintering technique is to develop silicon powder or a mix of silicon powder and also silicon nitride powder according to the basic manufacturing technique of ceramic items. Then, in the nitriding heating system, pre-nitriding is accomplished at 1150 ~ 1200 ℃. After obtaining a certain stamina, machining can be accomplished on the maker tool. Then, further nitriding is accomplished at 1350 ~ 1450 ℃ for 18 ~ 36h up until the products end up being silicon nitride. By doing this, the product size is precise, and the volume is secure. The hot pressing sintering technique is to incorporate silicon nitride powder with a handful of additives, such as MgO, Al2O3, MgF2, AlF3, or Fe2O3, Under the pressure of 19.6 MPa or over and also a temperature level of 1600 ~ 1700 ℃, the products made by warm pushing sintering are typically denser. They have much better properties than those made by reaction sintering.

Main applications of silicon nitride
Silicon nitride is used as innovative refractories, such as SI3N4-SIC refractories integrated with sic for blast furnace stack, as well as other components, such as SI3N4-BN products incorporated with BN for horizontal constant spreading separation ring. The SI3N4-BN series level constant casting splitting up ring is an acceptable ceramic material with a consistent structure, high mechanical strength, great warm resistance, and effect resistance. It will not be moistened by fluid steel, satisfying the procedure needs of continuous casting. On top of that, silicon nitride ceramic products have high thermal stability, strong oxidation resistance, and also high dimensional accuracy. Silicon nitride is a covalent substance with a high bond stamina and also can develop an oxide protective movie in the air, so it likewise has great chemical security. It will certainly not be oxidized below 1200 ℃. The protective film created at 1200 ~ 1600 ℃ can avoid more oxidation and also will certainly not be saturated or rusted by molten steels or alloys such as aluminum, lead, tin, silver, brass, as well as nickel. Still, it can be damaged by molten options such as magnesium, nickel-chromium alloy, stainless steel, etc Cost of
