Description

Mosi₂ heating element is a special product combined metal and ceramics. So it has the characteristics of silicon and molybdenum. Max. temp up to 1750℃.

It usually used as electric furnace heating elements.

Its main biggest advantage is anti-oxidation under high temperature. A layer surface called SIO₂ will come out and longer its life.

And the second benefit is that it will have no pollution on the sintered material.

Electric Property

1. Resistance Property

The resistivity of element rapidly rises as the temperature rises. Under normal operating conditions, the element resistance generally doesn't change with the service life, so the old elements can be used with the new elements together.

2. Surface Load

Choosing element surface load based on furnace structure, temperature as well as atmosphere, is the key of optimizing element service life. The below picture shows the relationship among the furnace temperature, element temperature and surface load under the circumstance that thermal element radiation is not hindered. The shadow part is for common surface load and temperature range.
