What is silicon nitride?
Silicon nitride is an essential architectural ceramic product with high firmness, lubricity, and use resistance. It is an atomic crystal that resists oxidation at heats. It can additionally stand up to cool as well as hot shocks. It can be heated to even more than 1000 ℃ in air, cooled down greatly, as well as then heated smartly without damaging. It is specific due to the fact that silicon nitride ceramics have such superb attributes that individuals often use it to make bearings, generator blades, mechanical seal rings, Irreversible molds, as well as various other mechanical parts. Expect silicon nitride porcelains that are immune to high temperature levels and challenging to warmth transfer are made use of to produce the heating surface areas of engine elements. Because instance, it can enhance the top quality of center extract engines and also save gas and thermal performance. China, the USA, Japan, as well as various other nations have actually established center extract engines.

The manufacturing technique of silicon
nitride There are two production methods of silicon nitride ceramic items, particularly response sintering as well as hot pressing sintering. The reaction sintering method is to create silicon powder or a mix of silicon powder and silicon nitride powder according to the general manufacturing method of ceramic items. Then, in the nitriding furnace, pre-nitriding is lugged out at 1150 ~ 1200 ℃. After getting a specific strength, machining can be accomplished on the device tool. Then, additional nitriding is performed at 1350 ~ 1450 ℃ for 18 ~ 36h till the products come to be silicon nitride. In this way, the product size is accurate, as well as the quantity is secure. The hot pushing sintering technique is to integrate silicon nitride powder with a small number of additives, such as MgO, Al2O3, MgF2, AlF3, or Fe2O3, Under the pressure of 19.6 MPa or above as well as a temperature of 1600 ~ 1700 ℃, the items made by warm pushing sintering are normally denser. They have better buildings than those made by response sintering.

Main applications of silicon nitride
Silicon nitride is made use of as advanced refractories, such as SI3N4-SIC refractories incorporated with sic for blast heating system pile, as well as other components, such as SI3N4-BN products combined with BN for straight continual spreading separation ring. The SI3N4-BN series level continual casting separation ring is an acceptable ceramic product with a consistent structure, high mechanical toughness, great warm resistance, and effect resistance. It will certainly not be wetted by liquid steel, fulfilling the process demands of constant spreading. On top of that, silicon nitride ceramic products have high thermal stability, solid oxidation resistance, and high dimensional precision. Silicon nitride is a covalent compound with a high bond toughness as well as can develop an oxide safety movie in the air, so it likewise has good chemical security. It will certainly not be oxidized below 1200 ℃. The protective film created at 1200 ~ 1600 ℃ can protect against further oxidation and also will not be saturated or corroded by molten steels or alloys such as aluminum, lead, tin, silver, brass, and nickel. Still, it can be damaged by molten options such as magnesium, nickel-chromium alloy, stainless steel, and so on Rate of
