The Properties And Applications of Silicon Nitride Ceramics

Silicon nitride The ceramics material is synthetic. In its structure, there is a strong covalent bond between nitrogen and silicon atoms. The silicon nitride is a ceramic with high hardness and strength. It also has good wear resistance.
Material industry has regarded silicon nitride materials as engineering ceramics with excellent comprehensive characteristics and that can be used at high temperatures.

The properties and applications of silicon-nitride ceramics

Normal temperature strength and high fracture toughness are characteristics of silicon nitride. They will maintain their strength at high temperatures. These are its main performances:

1. Material made of silicon nitride has a low coefficient of linear expansion, excellent thermal conductivity and thermal shock resistance.

2. The hardness is 99.5. This is only second to diamonds and BN.

It is also self-lubricating, wear-resistant and has a low friction coefficient.

4. It has a good mechanical property, high-temperature stability, high flexural and creep strength at high temperatures, and a good high temperature stability.

5.Silicon Nitride material is good at high temperature and has good insulation properties;

Application and Market Analysis of Silicon Nitride Ceramics

Silicon Nitride Powder Property

Silicon nitride (Si3N4) A covalent bonding compound made of silicon and nitrate. It was first discovered in 1857. In 1955, it was made into a mass-produced ceramic material. Silicon nitride clays offer many benefits that other materials, including metals and polymers, like high resistance to heat (bending strength of 350MPa at 1200), resistance to acid and alkali corrosion, self-lubrication, etc. These ceramics can be found in many areas, including aerospace and national defense.

Preparation The use of Silicon Nitride Ceramics

To prepare silicon-nitride ceramic material, it is necessary to first obtain silicon powder. Then, molding, sintering, and other processes are used to produce the required silicon nitride. There are three main ways to prepare the silicon nitride powder: liquid phase reaction, powder nitriding and self-propagating high temperatures synthesis.
There are three primary forming methods for silicon nitride ceramics: cold isostatic, dry, and tape pressing. Meanwhile, the major sintering processes include hot pressing sintering (hot isostatic pressing), spark plasma sintering, and air pressure sintering.

Silicon Nitride Ceramics Applications in Mechanical Industry

Silicon nitride Ceramics are used primarily as pipes, valves and tools for the mechanical industry. Most commonly, silicon nitride-carrying balls is used.

When in use, silicon nitride bearing balls can reach speeds of 600000 revolutions/minute. They are mainly used for precision machine tool spindles, high-speed motorized spindle bearings, aircraft engines, automobile engine bearings, and other equipment bearings.

The advantages of silicon nitride ceramic bearings ball over steel balls are: high density, low temperature resistance, self-lubrication, corrosion resistance and low density. Ceramic balls are high-speed rotating bodies that produce centrifugal pressure. The low density silicon nitride lowers the stress placed on the outer rotating ring.

Dense Si3N4 ceramics have high fracture toughness, high modus, self-lubricity and self-lubricity. This allows them to withstand various wear conditions, such as extreme temperature differences and ultra high vacuum. These bearings will likely be used widely in many industries.
