MoSi2 heating element is a resistance generate heating component made from MoSi2 or the basic material. It is used in high temperature under the oxidizing atmosphere,it looks like glass in its surface and form a light SiO2 glass film which can protect the element not to be oxidized.So this kind of element not to be oxidized.So this kind of element has unique effect for resisiting oxidization in the high temperature.It is used to the high temperature up to 1800C during oxidizing atmosphere. And the applicable temperature is 500-1700C.
We also call them dental silicon polisher or dental rubber polisher.
Made with Japanese rubber , silicon and aluminum oxides
