Silicon Carbide Rods

Silicon carbide rods are extremely strong cylindrical shapes formed from reaction-bonded silicon carbide for use in high-temperature applications. Silicon carbide rods’s working temperature can be up to 1625°C (2927°F), available in a wide variety of standard sizes and geometries, or in customized designs to meet the specific needs of various processes and equipment. SiC rods have more excellent specific rate of heat zone resistance and cold end resistance, saving energy, long life, avoiding over-temperature of cold ends to damage the furnace body.
