Silicon nitride (Si3N4) can be produced by various methods: sintered, using hot isostatic press or reaction bonded. In its sintered or pressed forms, it is obtained from a Si3N4 powder, mixed with organic binders, obtained in advance by nitriding the silicon powder (process coining a rise in temperature with a nitrogen-based gaseous environment).

Alibaba offers 798 silicon carbide vs silicon nitride products. A wide variety of silicon carbide vs silicon nitride options are available to you, Silicon Nitride balls: Size:1.588-101mm Grade:G5-G100 Silicon Nitride (Si3N4) is a widely used ceramic material in high
Silicon nitride bearing balls have a coefficient of thermal expansion just 25% if most steel balls, so there is less friction generated in the bearing as heat increases. The low thermal conductivity of silicon nitride balls reduces the amount of heat absorbed, thus reducing cooling system requirements.
