Silicon Carbide Ceramic Kiln Shelves Refractory With Alumina Coating 1. Introduction Silicon carbide kiln shelves has low coefficient of the thermal expansion,high thermal conductivity rate and perfect thermal shock resistance.It could be used in high speed thermal impact environment for many times.Silicon carbide has the performance of high strength and good thermal impact resistance.It can be used in the severe environment (such as high temperature,corrosion,erosion,etc)for long term.Silicon carbide is ideal material for ceramic industry, widely used in hightemperature kiln. 2.
