Silicon Nitride

Silicon nitride (Si3N4) granules are high-purity ceramic materials manufactured from silicon nitride. They offer excellent thermal stability, high hardness, outstanding oxidation resistance, and superior corrosion resistance, making them suitable for ceramic manufacturing, refractory materials, composite materials, and other industrial applications.

In addition to silicon nitride granules, VIMATERIAL also supplies silicon nitride powders and sputtering targets.
