Stable and reliable silicon nitride industrial wear parts can be produced and supplied by our company, for we have over 30 years experiences in the exploring and manufacturing .As a pioneer in China, we have supplied hundreds of silicon nitride products to different fields, such as aviation, aerospace, military, chemical, metallurgy, machinery, petroleum, energy and electronics etc. Many of them replace the imported ones and fill the blank in China.
Specially shaped silicon nitride parts can also be produced according to customers' requirements and drawings. Relying on powerful technical ability and normative quality management system, we can provide stable and precise silicon nitride parts and offer the best service to the customers.
The specifications are as follows:
Silicon nitride (Si3N4) material can be used in many fields because of its excellent comprehensive property.
1.High corrosion resistance. It can be used in strong acid and alkali situation.
2.High temperature stability. It can be used in high temperature situation, and the highest temperature can reach to 1400 degree.The strength and hardness in 1100 degree is almost the same as in room temperature.
3.Electrical insulation, non-magnetic. It can be used in magnetic field
4.Low density of 3.26g/cm3, high bending strength and high hardness. It can be considered as wear resistant materials.
5.Low thermal expansion coefficient of 3.2×10-6/K, which is 30% of Al2O3, and 40% of ZrO2. It can bear a sharp temperature change.
