Molybdenum Disilicide

Molybdenum disilicide heating elements (M_oS_i2) are made from S_iO_2.When it is burned in oxide atmosphere, a layer of S_iO₂ film comes onto the surface of the element. Even in oxide atmosphere, the element cannot be oxidized and can work from 1300℃ to 1800℃. You can use new elements and old elements at the same time. Parallel circuit or series circuit are both ok, and do not need to consider the matching of resistance. The elements provide a reliable heat source.

Application

Glass industry, metallurgy, ceramic refractory, pottery, heattreatment, furnace manufacture, electronics industry, magnetism material, military industry, scientific research, laboratory, universities, etc. It is an ideal element that used in sintering industry.
