It’s a crucial structural ceramic material and has high hardness. It is highly resistant to wear, lubricious, and is an atomic crystalline. Other than hydrofluoric acid or hot phosphoric, it is not reactive with any other inorganic acid. It also has strong resistance to corrosion. You can’t break it by heating up the air to over 1000°C, cooling down quickly, then heating again.
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 to make a mixture of silicon powder/silicon powder and silicon Nitride powder in accordance with the production process for ceramic products. It is then pre-nitrided at 1150-1200 to achieve a desired strength. The mixture is ready for machine on the machine machine. 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, or MgF2, and/or Fe2O3. They are sintered and pressed at a pressure of 19.6MPa or 1600 to 1700. Hot pressing sintering generally has a higher product density and greater performance than reaction sintering.
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 and wear resistance. It is therefore the ideal candidate for ceramics used in thermal engine parts. The mechanical industry uses silicon nitride ceramics as bearing balls, rolling, seat, 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 alloys and can be used to create tooling for metal processing such as extrusion, wire plucking, wire transfer, roll, heater fixture and thermocouple. It also has the ability to heat treatment support metals like crucible, guide and lining.
