L Shape MoSi2 Resistive Electric Heating Element
Product Description
Mosi2 heating element is a special product combined metal and ceramics. So it has the characteristics of silicon and molybdenum.Molybdenum disilicide (MoSi2) is a refractory metal silicide that is primarily used as a heating element.In recent years, its potential for use as a structural ceramic has been recognised, as the material combines excellent oxidation resistance and high elastic modulus at elevated temperatures.

2.Chemical porperty
The element cannot be used for rather long time in 400-700 ℃,otherwise ,it will be atomized owing to the strong oxdizing action in low temperature.

Following should be provided when ordering L Type or Bent 90° MoSi2 Heating Elements:
Grade: 1700, 1800
Diameter of Cold Zone / Hot Zone: c/d, in/in or mm/mm
Length of Hot Zone: Le*, in. or mm
Length of Code Zone: Lu*, in. or mm (Lu includes l, k and m as in the drawing below)
Shank Spacing: a*, in. or mm
Specify Le, Lu, and a with the same units (e.g. all as in. or mm).
Examples:
Grade 1800, d=6mm, c=12mm, Le=950mm, Lu=650mm, a=50mm
Specify as: MS18L, 6/12x950x650x50mm
Specification
Spark MS18L MoSi2 Heating Element
High temperature MoSi2 heating element for various electric furnaces.
Max. working temperature 1730℃ ( 3346°F )
Compact protective layer of quartz glass
Long life combined with ease of replacing failed elements contributes to a high degree of utilization of the furnace and low maintenance costs.
New and old elements can be connected in series
Can be used continuously or intermittently
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.
