U type Mosi2 Heating elemet
[Chemical Properties]
High temperature oxidation resistance: Under high temperature oxidation atmosphere, a dense quartz SiO2 protective layer is formed on the surface of the component to prevent further oxidation of MOSi2. When the temperature of the component exceeds 1700 ℃ and the quartz protective layer with a melting point of 1710 ℃ melts off, due to the surface tension, the quartz melts into droplets and loses its protective effect. When the component is used again in an oxidizing atmosphere, the quartz protective layer is regenerated
It must be pointed out that the components should not be used for a long time in the range of 400-700 ℃, otherwise the components will pulverize due to strong oxidation at low temperatures.
The influence of different atmospheres on component temperature
Under an oxidizing atmosphere and at a usage temperature of 1800 ℃, the resistance of silicon molybdenum rod electric heating elements increases rapidly with increasing temperature, and the resistance value remains stable when the temperature remains constant. Under normal circumstances, the resistance of the component does not change with the length of use, so new and old silicon molybdenum rod electric heating elements can be mixed for use. Correctly selecting the surface load of the silicon molybdenum rod electric heating element based on the structure, working atmosphere, and temperature of the heating equipment device is the key to the service life of the electric heating element.
