Product Description

Hot Sale in USA U Shape 4/9 molybdenum disilicide Mosi2 electric furnace heater Heating Element for Dental Furnace for Dental
Molybdenum disilicide(MoSi2) heating element/heater:

Molybdenum disilicide (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 has unique effect for resisting oxidization in the high temperature. It is used to the highest temperature up to 1800 degree celsius during oxidizing  atmosphere. According to your request, our company can produce the products of Pole, "U", "W" and "U"-right angle shapes, etc

Having the same mechanical character as other ceramic products , MOSI2 heating elements are brittle materials so that they are easy to rupture at the normal temperature , which brings some difficulties to transport and install , but it may be avoided if they were  installed and used correctly .

Chemistry Character
MoSi2 heating element  is used in the high temperature under oxidizing atmosphere. It will form the SiO2 film which can keep the element from being melted. During the oxidizing process, the SiO2 protecting film is formed again when the element continues to be used. The MoSi2 heating element must not be used in the temperature between 400C and 700C for a long time, otherwise the element will be cremated under the strong oxidizing function in the low temperature.
