What is silicon nitride?
Silicon nitride is an important architectural ceramic product with high hardness, lubricity, as well as use resistance. It is an atomic crystal that withstands oxidation at high temperature levels. It can also hold up against cool and also hot shocks. It can be heated to greater than 1000 ℃ in air, cooled sharply, and afterwards warmed wisely without breaking. It is accurate due to the fact that silicon nitride ceramics have such superb characteristics that individuals often use it to make bearings, wind turbine blades, mechanical seal rings, Permanent molds, and various other mechanical parts. Suppose silicon nitride porcelains that are resistant to heats and also not easy to warmth transfer are used to manufacture the home heating surface areas of engine components. In that case, it can improve the high quality of middle distillate engines and conserve fuel as well as thermal efficiency. China, the USA, Japan, as well as various other countries have established middle distillate engines.

The manufacturing approach of silicon
nitride There are 2 production methods of silicon nitride ceramic products, particularly response sintering and also hot pushing sintering. The response sintering technique is to develop silicon powder or a combination of silicon powder and silicon nitride powder according to the basic manufacturing technique of ceramic items. Then, in the nitriding furnace, pre-nitriding is executed at 1150 ~ 1200 ℃. After acquiring a specific stamina, machining can be performed on the machine device. Then, additional nitriding is accomplished at 1350 ~ 1450 ℃ for 18 ~ 36h till the items become silicon nitride. By doing this, the item dimension is precise, as well as the quantity is stable. The hot pressing sintering approach is to incorporate silicon nitride powder with a tiny number of additives, such as MgO, Al2O3, MgF2, AlF3, or Fe2O3, Under the stress of 19.6 MPa or over as well as a temperature of 1600 ~ 1700 ℃, the items made by warm pushing sintering are normally denser. They have better residential or commercial properties than those made by response sintering.

Main applications of silicon nitride
Silicon nitride is made use of as innovative refractories, such as SI3N4-SIC refractories combined with sic for blast furnace pile, and other parts, such as SI3N4-BN materials combined with BN for horizontal continual spreading separation ring. The SI3N4-BN series flat continual casting separation ring is an acceptable ceramic material with an uniform structure, high mechanical strength, great heat resistance, as well as influence resistance. It will certainly not be wetted by fluid steel, satisfying the procedure demands of continuous casting. On top of that, silicon nitride ceramic materials have high thermal stability, solid oxidation resistance, and high dimensional precision. Silicon nitride is a covalent compound with a high bond toughness and can form an oxide safety movie airborne, so it additionally has excellent chemical stability. It will certainly not be oxidized below 1200 ℃. The protective film created at 1200 ~ 1600 ℃ can avoid more oxidation and will not be saturated or worn away by molten metals or alloys such as light weight aluminum, lead, tin, silver, brass, as well as nickel. Still, it can be damaged by molten solutions such as magnesium, nickel-chromium alloy, stainless-steel, etc Rate of
