Silicon nitride

It is an organic substance having the chemical formula SI3N4. Silicon nitride can be used as a structural ceramic material. It has high hardness, lubricity, and wear resistance. Silicon nitride can be very strong, particularly when hot-pressed. This is why it is one of the strongest materials in the universe.

Silicon Nitride Powder Properties

Silicon nitride does not interact with water. Instead, it is slowly hydrolyzed by strong acid to create ammonium salt and silica dioxide. It is also easily soluble in hydrofluoric acids and is incompatible with dilute acids. Strong alkali solutions can slowly corrode silica nitride. Molten alkali can transform silicon nitride quickly into silicate and ammonia.

Silicon nitride has a very high resistance to high temperatures. Its strength can be maintained at a temperature of 1200°C without falling. It won’t melt in heat and it won’t decompose after heating. It is very resistant to chemical agents. Silicon nitride has remarkable chemical resistance. It can withstand most inorganic acids, caustic soda solution below 30%, and corrosion by many other organic acids.

Silicon Nitride Powder Applications

The high strength and resistance to heat of silicon nitride clays are some of the highlights. It has the best overall mechanical properties, thermal shock resistance as well as oxidation resistance. It is the original ceramic used in thermomechanical components. This is a potential material. A candidate material.

In the chemical sector, silicon nitride clays are used for wear-resistant, corrosion-resistant parts like ball valves and pump bodies.

The silicon nitride clays used in the metallurgical sector are durable, low friction, and self-lubricating. It is stable to most alloy and metal solutions. It can therefore be used for the production of metal material processing tools, including dial mandels, extrusion, wire drawing and transfer dies as well as rollers, transfer dies and heating element fixtures.

It has excellent properties and is used to create bearings, turbine blades and mechanical seal rings. It can improve the quality and efficiency of diesel engines by using silicon nitride clays which are resistant at high temperatures and hard to transfer heat.
