MOSI2 Heating elements 1800 is a high density material consisting of molybdenum disilicide (MoSi,) and self forming glaze of silicon dioxide (SiO2). It can be used upto 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.
Silcarb manufactur es its MoSi2 Heating Elements by Hot pressing and hot extrusion and also pressure assisted sintering techniques. Silcarb uses Hot isostatic pressing to produces complex shapes, with uniform density and grain structures. The best grade of MoSi2 Heating Elements is capable of operating at temperatures up to 1800℃. However, the material is extremely brittle and can suffer creep from use. Silcarb uses state of the art technology to produce Heating elements that can operate at high electric loads without aging. MoSi2 heating elements are supplied as ready-made elements, and are produced as either straight, bent forms or multi shank elements and in a wide range of dimensions. The elements are used mainly in laboratory furnaces and production furnaces in the glass, electronics, steel, ceramics and heat treatment industries.
