Chemical property of MoSi2
High temperature oxidation resistance:
When MoSi2 heating elements are used at high temperature and under oxidation circumstance, a dense layer of quartz (SiO2) is generated on the surface of the element to prevent it from further oxidation.
When the temperature of element is over 1700oC, the SiO2 protecting film whose melting point is 1710oC will be melted. Due to its surface tension, SiO2 agglomerate() into drops and lose protection. The SiO2 protecting film is formed again when the element continues to be used under the oxidation circumstance.
It must be pointed out is that the MoSi2 heating element cannot be used in the temperature between 400oC to 700 oC for long time. Otherwise, the element will be pulverized because of the strong low-temperature oxidation.
?
Resistance characters
?
MoSi2 heating elements have good resistance characteristic, so it is an ideal heating material to replace traditional heating elements.
?
At room temperature, its resistivity is very low, with the increase of temperature, the resistance increases sharply. The advantages of heating up fast and low power consumption are obvious.?
?
In normal operating circumstances, the resistance of the element is constant, so the old and new components can be mixed.
