What is Silicon Nitride? Silicon Nitride Is an organic substance that has the chemical composition Si3N4. Gray, grayish-white or white. The relative molecularweight is 140.28.
It is a crucial structural ceramic material and has high hardness. It is a high-temperature antioxidant and has wear resistance and lubricity. It does not react to hydrofluoric and hot phosphoric acids, and is strong resistant to corrosion. It is also resistant to cold and heat shocks.
It is often used to make mechanical components, such as bearings and gas turbine blades. It can improve the quality and efficiency of engine parts by using silicon nitride clay that is resistant to heat transfer and high temperatures.
How to make silicon nitride clays?
Two primary production methods are available for silicon nitride ceramic products. These are reaction Sintering, and Hot-Pressing Sintering.
The reaction Sintering technique is used to produce the mixture of silicon powder/silicon powder and silicon Nitride powder according to the standard production method for ceramic products. It is then pre-nitrided at 1150-1200 to achieve a certain strength. Then it can be machined using the machine tool. Then, it is further nitrided for 18-36h at 1350-1450 until all of its substance is transformed into silicon nitride. The product size and volume are stable because of this method.
The hot-pressing rule stipulates that silicon oxide powder and a small quantity of additives (such MgO, Al2O3, AlF2, AlF3, or Fe2O3) must be used. They are sintered and pressed at a pressure of 19.6MPa or 1600 to 1700. In general, hot pressing sintering produces a product with a higher density and greater performance than reaction sintering.
What’s silicon nitride ceramic for?
Silicon nitride clays are strong and resistant to high temperatures. The ceramic material silicon nitride ceramics has the highest comprehensive mechanical properties. It is also resistant to oxidation, wear, wear, and thermal shock. Silicon nitride clays are used in the mechanical sector as bearing balls and rollers, seats, tooling, pumps, sealants, mandrel sealing material, and so forth.
The chemical industry uses silicon nitride clays as wear-resistant, corrosion-resistant parts. This includes the ball valve, pump body and combustion carburetor.
Silicon nitride ceramics, which are high-temperature resistant and have a low friction coefficient, provide self-lubricity in the gold mining industry. It is compatible with most metals and alloy solutions. This makes it ideal for tooling in metal material processing.
