What’s theMosi2 Electric Heater Element?
Molybdenum disilicide(MoSi2) heating element is one resistance heating component made from MoSi2 or as the basic material. When it’s heated to high temperature under the oxidizing atmosphere, one dense MoSi2film will be formed on its surface to protect the element against oxidizing further. Therefore, the element has unique anti-oxidation property under high temperature atmosphere. The highest temperature can reach 1800°C, the applicable temperature is between 500-1700°C.
MoSi2 has been produced as an electric heating element for use in air, at temperatures beyond 1600 °C. A known commercial MoSi2 heating element is cermet, which is made by bonding a mixture of MoSi2 particles together with an aluminosilicate glass phase, usually as 20% of the total volume.
Although top-grade MoSi2 elements can function at temperatures of up to 1800 °C, the material is highly brittle and can suffer severely from creep during use. However, they offer process benefits as they can work at high electrical loads without aging, and do not exhibit increasing electrical resistivity during use. They are oxidation-resistant in air, oxygen, and oxygen-rich atmospheres.
