Silicon Carbide (SiC) Heater – Maltec-H

SIC heater is a kind of non-metal high temperature electric heating element. It is made of selected high-purity green silicon carbide as raw material which is made into blank and silicon crystal under high temperature of 2400ºC. SiC can usually use in the furnaces which temperature from 600°C -1600°C. It can be directly used in an air atmosphere without any protection atmosphere, the long-term usage of life can reach over 3000 hours.  Furthermore, it has a higher working temperature and chemical stability, easy installation and extensively used in the fields of metallurgy, ceramics, glass, machinery, analysis test, semiconductor, science and so on.

Silicon carbide is a ceramic material with relatively high electrical conductivity when compared to other ceramics. Typical heating elements are rods or tubes, with diameters between 0.5 and 3 inches and lengths from 1 to 10 feet. They have metalized ends for electrical connections, and they often have both connections at one end, with two helical slots that stop short of the other end, thus approximating a twisted hairpin form.
