What exactly is silicon nitride? Silicon Nitride Is an organic substance that has the chemical formula Si3N4. It comes in gray, white and grayish-white colors. The relative molecular mass is 140.28.
It’s a crucial structural ceramic material and has high hardness. It is highly resistant to wear and lubricious. Other than hydrofluoric acid or hot phosphoric, it is not reactive with any other inorganic acids. It also has strong corrosion resistance. You can also resist hot and cold shock, heat up of more than 1000, fast cooling and heating.
The excellent qualities of silicon nitride clay mean that they are often used in the manufacture of mechanical components, such as bearings. It can be used to make the heating surface for engine parts of silicon nitride clay, which is heat resistant and easy to heat.

How can you produce silicon nitride clays?
The main two methods to produce silicon nitride ceramic products include reaction heating and hot pressing heating.
The react sintering technique is used to make the combination of silicon powder/silicon powder and silicon-nitride powder following the standard production process for ceramic products. It is then pre-nitriding at 1150-1200 to obtain a desired strength. Then it can be machined using the machine tool. Next, it is further nitrided for between 18 and 36 hours at 1350-1450 until all the material is transformed to silicon dioxide. The product size and volume are stable because of this method.
The hot pressing sintering rule states that silicon nitride must be mixed with small amounts of additives, such as Al2O3, Al2O3, AlF2, AlF3, Fe2O3, Fe2O3, etc. They are pressure pressed at 19.6MPa. Then, the temperature at 1600 to 1700 is used. Reaction sintering produces a product with a lower density and greater performance.

How is silicon-nitride ceramic used?
The characteristics of Silicon Nitride ceramics are high strength and resistant to heat. The ceramic material silicon nitride has the highest comprehensive mechanical characteristics, including thermal shock resistance as well as oxidation resistance, wear resistance, and corrosion resistance. It is therefore the ideal candidate for ceramics used in thermal engine parts. The mechanical industry uses silicon nitride in ceramics as bearing balls, rolling, seats, tooling and new ceramic tools.
The chemical industry uses silicon nitride clays as wear-resistant, corrosion-resistant components. 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 industry. This ceramic is suitable for all metals and alloy solutions. It can be used to create tooling for metal processing such as wire plucking, extrusion, transfer rollers and heater fixtures.
