MoSi2 Heating Element Description
MoSi2 Heating Element are resistive heating elements based on molybdenum disilicide. The temperature generated by MoSi2 goes as high as 1700~1800°C in oxidation atmosphere. They can be widely used in such applications as sintering and heat treatment on electronic ceramics, structural ceramics, magnetic materials, flameproof materials, glass, metallurgy, etc.

Advantage
Elements have the capabilities to resistance to oxidation and automatically repair, suitable for continued using in any kinds of oxidizing atmospheres.Elements are shaped in hot-working process, which keeps the base material in good tenacity and plasticity at high temperatures. The geometrical figure, standard and dimension is canonical, may produce any special shape and any dimension to meet the customer requirement.Because of the special technology, welding spot is fast and shock resistance, which dramatically reduced the damaged probability of welding spot by electric current, as well as transit and installation.High density of Spark MoSi2 Heating Elements increases its electrical conductivity. The characters of faster warming and power consumption low, which reduce production cost.Good appearance quality and tenacity, high mechanical strength.Adopt special technology, heaters come with compact protective layer, excellent performance in no-oxidizing atmosphere electric furnaces.
Note: For inquiry, it is better to provide a drawing of the element and specify the element diameters in millimeters. For example, an element with a (d) diameter of 9 mm and a (c) diameter of 18 mm is often referred to as a 9/18 element. Other dimensions may be specified in millimeters or inches.
