Silicon Carbide Tube Description

Silicon carbide (SiC) is a lightweight ceramic material with high strength properties comparable to diamond. It has excellent thermal conductivity, low thermal expansion and is resisitance form acids. Silicon carbide ceramic is excellent for applications requiring good erosion and abrasive resistance. Consequently, it is useful in a variety of applications including spray nozzles, shot blast nozzles, ceramic tubing and cyclone components.

We produce sintered SiC tubes, reaction bonded SiC tubes and recrystallized SiC tubes. Our recrystallized SiC products have a high purity, while our reaction bonded and sintered silicon carbide tubes have a high mechanical strength. Our silicon carbide tubes possess good wearability,a low thermal expansion coefficient, extreme corrosion resistance, wear resistance, thermal shock resistance, high hardness and self-lubricating properties.
