What exactly is silicon nitride Silicon Nitride Formula Is Si3N4. Two crystal types of silicon nitride exist: A and B. The granular form is Si3N4, while the acicular is p-Si3N4. Both are part of the hexagonal structure.
Relative density for silicon nitride (SiN) is 3.18 Silicon nitride’s Morse hardness range is 9. It has a low coefficient of thermal expansion, excellent chemical stability, and excellent oxidation resistance. The material is decomposed into silicon and nitrogen at 1900. Silicon nitride has a very strong strength and is resistant to heat. Even at 1200°C, the strength of silicon nitride will not be affected. It won’t melt even if heated. The material will continue to be inert until the year 1900. It can resist corrosion of nearly all organic and inorganic acids. Silicon nitride is hard and has a low coefficient of thermal extension. It also exhibits excellent thermal shock stability.

What advantages does silicon nitride offer?
The low thermal expansion of silicon nitride makes it superior to other technical ceramics in terms of thermal shock resistance. It’s extremely durable, with a high melting point and excellent resistance to oxidation. It can therefore endure the toughest high temperature or high load situations.
Silicon nitride bearings are used in space shuttle’s main engines. They have been identified as being one of very few ceramic materials which can resist severe thermal shocks or thermal gradients caused by oxygen and hydrogen rocket engines. This material has proven reliable and stable throughout the whole space shuttle programme.
Why is silicon Nitride used?
It is used for heat engine materials and insulating materials.
Silicon nitride clays can be used for combustion chambers of gas turbines, as well as to seal the pipeline, valve, and pipe of an electromagnetic pump. They are useful in conveying liquid aluminum, permanent mould, and molten-steel separation rings.
It has a low friction coefficient, and it is often used for high-temperature bearings. The working temperature of silicon nitride can exceed 1200°C, which is 2.5x higher than the working temperature of normal alloy bearings. Its work speed is also 10x faster than those of regular bearings.
A silicon nitride-ceramic with high electrical insulation and resistance to heat and cold can be used for an electric plug. It can significantly reduce engine start time, and allow the vehicle to begin quickly even in freezing weather.
High temperature resistance, good microwave permeability, high dielectric properties and excellent heat strength make silicon nitride ceramics ideal for radar radomes on aircraft and missiles.
