Silicon nitride | DEV SICT
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).
