Silicon Nitride Powder

Silicon Nitride Powder

Short Description:

Power for silicon nitride (Si3N4) is light, hard, and has low thermal expansion coefficient. Silicon Nitride Powder has high mechanical strength, fracture toughness, and it is resistant to deformation at room temperature as well as at elevated temperature. Si3N4 differs from other ceramics because it doesn’t melt, but, between 1800 and 1900 °C, it decomposes and sublimates into Si and N. However, stabilized forms can be made. Engine parts: valves, pistons, etc. Gas turbines Diesel engin...
