What is silicon nitride?
Silicon nitride is a vital architectural ceramic material with high solidity, lubricity, and put on resistance. It is an atomic crystal that stands up to oxidation at heats. It can additionally stand up to cool and also warm shocks. It can be heated up to greater than 1000 ℃ in air, cooled down greatly, as well as then warmed wisely without damaging. It is precise since silicon nitride porcelains have such exceptional features that people frequently utilize it to produce bearings, turbine blades, mechanical seal rings, Irreversible mold and mildews, and also various other mechanical parts. Intend silicon nitride porcelains that are resistant to heats and also hard to warmth transfer are made use of to manufacture the heating surface areas of engine components. Because case, it can enhance the top quality of middle distillate engines and save fuel and thermal performance. China, the USA, Japan, and other countries have actually created center extract engines.


The manufacturing technique of silicon
nitride There are 2 production techniques of silicon nitride ceramic products, particularly response sintering as well as warm pressing sintering. The reaction sintering method is to form silicon powder or a combination of silicon powder and silicon nitride powder according to the basic production approach of ceramic products. Then, in the nitriding heating system, pre-nitriding is performed at 1150 ~ 1200 ℃. After acquiring a particular strength, machining can be executed on the machine tool. Then, more nitriding is performed at 1350 ~ 1450 ℃ for 18 ~ 36h until the items end up being silicon nitride. By doing this, the product dimension is precise, and the quantity is steady. The hot pressing sintering approach is to integrate silicon nitride powder with a small number of additives, such as MgO, Al2O3, MgF2, AlF3, or Fe2O3, Under the stress of 19.6 MPa or over and also a temperature of 1600 ~ 1700 ℃, the items made by warm pushing sintering are usually denser. They have better residential or commercial properties than those made by response sintering.

Primary applications of silicon nitride
Silicon nitride is made use of as innovative refractories, such as SI3N4-SIC refractories incorporated with sic for blast heater pile, and also other components, such as SI3N4-BN products integrated with BN for horizontal constant casting separation ring. The SI3N4-BN collection level continuous spreading splitting up ring is an acceptable ceramic material with a consistent framework, high mechanical stamina, great warm resistance, and also impact resistance. It will certainly not be wetted by fluid steel, satisfying the process requirements of continual spreading. Additionally, silicon nitride ceramic products have high thermal stability, strong oxidation resistance, and high dimensional precision. Silicon nitride is a covalent substance with a high bond strength and can create an oxide safety film airborne, so it also has excellent chemical security. It will not be oxidized below 1200 ℃. The safety film produced at 1200 ~ 1600 ℃ can avoid further oxidation and also will certainly not be soaked or worn away by molten steels or alloys such as light weight aluminum, lead, tin, silver, brass, and also nickel. Still, it can be damaged by molten services such as magnesium, nickel-chromium alloy, stainless-steel, etc Cost of
silicon nitride
Silicon nitride bit dimension as well as purity will certainly influence the product'' s Price, as well as the acquisition quantity can also impact the price of silicon nitride. A large amount of huge quantity will be lower. The Price of silicon nitride can be found on our company'' s main website.
