Sialon Vs Silicon Carbide - Manufacturer | Supplier
2019/6/27· Silicon carbide remained the hardest synthetic material available until 1929. As well as its exceptional hardness, it also has an outstandingly high thermal conductivity. This, together with its chemical reaction resistance and low thermal expansion, makes it ideal for use in refractories and in manufacturing high-temperature bricks.

Monocrystalline silicon carbide wafers have demonstrated high voltages and current densities eight times greater than silicon, but have small holes, called micropipes. Like holes in a high-pressure hose, micropipes nuering up to 50 per square centimeter, allow current to rush through in an avalanche breakdown of the transistor.
