What is slot type sic heating element?
The slot type SiC heating element is manufactured with a spiral-grooved heating section which is made of homogeneous, high-density silicon carbide crystals.
It is more resistant to heat and corrosion than conventional products. It is also able to withstand operations in rigorous conditions.
