Heating elements in high purity six green silicon carbide as the main raw material,according to a certain ratio of material and processing of billet, bar, pipe by 2200 degrees high temperature sintering and made the silicified recrystallization. The temperature can reach 1400 DEG C for normal use in an oxidizing atmosphere, the silicon carbide with high temperature life is shorter, therefore in the furnace temperature of over 1400 DEG C,oxidation speed, shorten the life span of attention, use as far as possible not to let the silicon carbide surface temperature is too high. Convenient installation and use, does not require the use of transformer. Has the advantages of high temperature resistance,oxidation resistance, corrosion resistance, long life, fast heating, high temperaturedeformation is small, convenient installation and repair, and have good chemical stability.Has been widely used in electronic, magnetic material, powder metallurgy, ceramics, glass,semiconductor, high temperature field analysis laboratory, such as scientific research, atunnel kiln, roller kiln, glass furnace, vacuum furnace, smelting furnace, Ma Fulu and all kinds of heating equipment, electric heating element.
