Silicon Nitride Powder

Product Description

Si3N4 is one of our featured products and we specialize in it for almost 10 years.
Silicon nitride(Si3N4):
Silicon nitride (Si3N4) is a chemical compound of silicon and nitrogen. It is light, hard, and has low thermal expansion coefficient. It has high mechanical strength, fracture toughness, and it is resistant to deformation at room
Temperature as well as at elevated temperature.
The α And β Phases are the most common forms of Si3N4, and can be produced under normal pressure condition
Usage:
Silicon nitride has long been used in high-temperature applications.
It is widely used in steelmaking, refining and smelting special steel, foundry industry.
The major application of Si3N4 was abrasive and cutting tools. Grinding, milling, and boring of metals constitute the major cost of manufacturing.
