Hotohms™Silicon Carbide Heating Elements are non-metallic electric heating components that  made of top-quality SiC as its main raw materials.  silicon carbide rod has a higher working temperature and chemical stability and long serivce life , easy installation and maintanance etc. 
SiC can usually make use for furnace which temperature from 600℃-1600℃. It can be directly used in an air atmosphere without any protection atmosphere, the long-term usage life can reach over 3000 hours. It is extensively used in the fields of metallurgy, ceramics, glass, machinery,analysis test, semiconductor, science & research and so on.
