The MoSI2 element is a dense cermet material consisting of molybdenum disilicide (MoSi2) and a glassy phase silicon dioxide (SiO2). The element is a resistance type heating element that converts electrical energy to heat energy . MoSi2 heating elements are characterized by good heat and electrical conductivity.
They have low thermal expansion and withstand corrosion and oxidation. all characterized by long life and consistent performance. element temperatures up to 1850°C (3360°F)
The elements are most frequently used suspended with the bottom of the hot down. The element consists of two cold ends (Lu) . The cold ends are twice the diameter of the hot section and are attached by a weld. The extremities of the cold ends are metallized with aluminum to provide a low-resistance contact surface to which the electrical connections are made with flat braided aluminum straps the elements are available as straight or bent elements in a wide range of shapes and sizes, .

QS MOSI2 heating elements , Half Cylinders, and Flat Panel Heaters The module consists of a high temperature ceramic fiber cylinder and a molybdenum disilicide heating element.
The molybdenum disilicide is the same material we use for the U shaped heating element. The heating element is in contact with the fiber therefore the temperature of the element is limited to 1600ºC. The highest practical muffle furnace temperature is 1550ºC. The heating module makes a neat little muffle furnace capable of rapid heat up, accurate temperature control and uniform temperatures. The module comes assembled in various diameters and lengths. The most popular shaped module has the Moly-D element spirally wound, set in grooves, and stapled in the internal diameter inside the fiber cylinder. When it is desirable to open the furnace or muffle in two halves along the muffle axis, the heating module is supplied in half cylinders. On half cylinders the heating elements are formed into continuous hairpins (U-shaped).
The MOSI2 material is stapled to the fiber module. Both types of heating modules can be used with the axis of the muffle horizontal or vertical. For the half cylinder modules, a different staple arrangement is necessary therefore the operating position must be specific when ordering the module.
