1.Silicon carbide tube Description

Silicon carbide tube has a low coefficient of thermal expansion, high thermal conductivity rate, and perfect thermal shock resistance. It could be used in high-speed thermal impact environments many times. Silicon carbide has the performance of high strength and good thermal impact resistance. It can be used in a severe environment in the long term. Silicon carbide is an ideal material for the ceramic industry, widely used in a high-temperature kiln.
