SIAION ceramic based on alpha-Si3N4

Silicon nitride (Si3N4) is a light, hard and strong engineering ceramic(1,2). It can withstand harsh nvironments and support heavy loads at temperatures beyond those at which metals and polymers fail. It can also be manufactured reliably at a reasonable cost and in large quantities. There are two forms of silicon nitride(3): alpha-Si3N4 and beta-Si3N4. The former is harder, but only the latter is currently used in engineering Read More…
