Mosi2 rod resistance has excellent high temperature oxidation resistance, but at lower temperatures, especially 400-700 degrees, it will undergo low temperature oxidation and powdering phenomenon. After long term low temperature working, mosi2 rod will oxidize and become brittle and crumbly. Cracks or even local collapse may occur after large current passes and high and low temperature alternation. Therefore, we should avoid long-term use of the element temperature at 400-700 degrees when using it, such as in the oven, try not to keep the insulation stage for too long.
