MOSIL Range of Molybdenum Di-Silicide Heater(MoSi2 Heating Element)
MOSIL 1800 is a high-density material consisting of molybdenum disilicide (MoSi2,) and self-forming glaze of silicon dioxide (SiO2). It can be used up to Furnace Temperature of 1800°c. These Elements do not age and have a long service life.
The Temperature of around 1200°c the Element becomes ductile. It is brittle at Temperature below 1200°c.
The elements are U shaped and are mostly used suspended with the bottom of the “U” down. The element consists of two cold ends(Lu) and a U-shaped hot section(Le). The cold ends are twice the diameter of the hot section and are attached by a weld. The extremities of cold ends are metallized with aluminium to provide a low-resistance contact area to which the end zones are made with flat braided aluminium straps.
