Silicon Nitride(Si3N4) 【EnoMaterial】
Silicon Nitride Powder
1. The characteristics of Silicon Nitride Powder.
Silicon nitride powder (Si3N4) 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. 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.
2. The applications of Silicon Nitride Powder.
（1）chemical engineering pump-used and caldron-used mechanical seal ring.
（2）The products of all kinds of shaft, bushing, plunger, cylinder, bearing and so on.
（3）Temperature-measuring thermocouple sleeve pipes, all kinds of airflow pipes and sand-blast pipes of high temperature endurable, corrosion endurable, deterioration endurable and so on.
（4）All kinds of mechanical spares and blades of corrosion endurable, high temperature endurable, deterioration endurable and so on.
（5）In addition, silicon nitride materials in other industries have wide applications. Such as Engine parts: valves, pistons, etc. Gas turbines Diesel engines .
