There are different kinds of electric heating elements: mosi2 heaters, SiC heaters, alloy wire heating elements. Mosi2 heating elements are usually applied for the electric furnaces whose working temperature is about 1200-1800°C, there are advantages for such furnaces: in a variety of shapes and sizes and feature the highest operating temperatures and watt loadings of the elements under consideration. They also have stable resistance, which allows new and old elements to be connected in series. Fast thermal cycling is possible without element degradation, and the elements are relatively easy to change while the furnace is hot. MoSi2 elements also offer the longest inherent life of all electric heating elements.
