What is silicon nitride?
Silicon nitride is a crucial structural ceramic product with high firmness, lubricity, and also use resistance. It is an atomic crystal that resists oxidation at high temperature levels. It can likewise stand up to cool as well as warm shocks. It can be heated up to even more than 1000 ℃ in air, cooled sharply, and after that heated smartly without breaking. It is specific due to the fact that silicon nitride ceramics have such exceptional attributes that people usually utilize it to make bearings, generator blades, mechanical seal rings, Irreversible molds, and also other mechanical parts. Mean silicon nitride ceramics that are immune to heats and also challenging to warm transfer are made use of to make the heating surface areas of engine parts. In that case, it can boost the top quality of center distillate engines and also save fuel and thermal efficiency. China, the United States, Japan, and also various other countries have actually created center distillate engines.

The production approach of silicon
nitride There are 2 production techniques of silicon nitride ceramic items, namely response sintering and warm pressing sintering. The response sintering approach is to develop silicon powder or a mix of silicon powder and also silicon nitride powder according to the general manufacturing method of ceramic items. Then, in the nitriding heating system, pre-nitriding is accomplished at 1150 ~ 1200 ℃. After acquiring a certain toughness, machining can be executed on the device device. Then, more nitriding is executed at 1350 ~ 1450 ℃ for 18 ~ 36h until the products become silicon nitride. In this way, the product size is exact, as well as the volume is secure. The warm pushing sintering method is to integrate silicon nitride powder with a small number of ingredients, such as MgO, Al2O3, MgF2, AlF3, or Fe2O3, Under the stress of 19.6 MPa or above as well as a temperature of 1600 ~ 1700 ℃, the products made by warm pushing sintering are typically denser. They have much better homes than those made by reaction sintering.

Main applications of silicon nitride
Silicon nitride is utilized as advanced refractories, such as SI3N4-SIC refractories combined with sic for blast furnace stack, and other components, such as SI3N4-BN products integrated with BN for straight continuous spreading splitting up ring. The SI3N4-BN collection level constant spreading splitting up ring is an appropriate ceramic product with an uniform framework, high mechanical stamina, good warm resistance, and also influence resistance. It will not be wetted by fluid steel, meeting the process demands of continuous spreading. Additionally, silicon nitride ceramic materials have high thermal stability, solid oxidation resistance, and also high dimensional accuracy. Silicon nitride is a covalent substance with a high bond toughness and can create an oxide safety movie in the air, so it likewise has great chemical security. It will not be oxidized below 1200 ℃. The protective movie produced at 1200 ~ 1600 ℃ can prevent further oxidation and will certainly not be saturated or corroded by molten steels or alloys such as light weight aluminum, lead, tin, silver, brass, and nickel. Still, it can be damaged by molten remedies such as magnesium, nickel-chromium alloy, stainless steel, and so on Price of
