Custom High Purity SiC Coated Graphite Heater Heating Element

Short Description:

Graphite heater is a kind of electric heating material that generates heat by heating graphite material electrically, usually made of graphite and ceramics. Its wavy structure can effectively dissipate heat and is widely used in industry, construction, agriculture and daily life. Because of its good thermal conductivity and high temperature stability, graphite heating element is widely used in industry.
