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 MoSi2 film 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.

Applications: It can be used as heating elements of industrial high-temperature furnace, like ceramics, magnetic materials, glasses, metallurgy, refractory, etc.

Advice of Installation

1.  MoSi2 heating element is very brittle under room temperature but plastic in high temperature, so it's better to install the U type element hanging vertically. The aim is to avoid putting the mechanical stress directly to the Hot Zone of the element, otherwise, the element will be broken easily. If hanging horizontally installation, please use high temperature refractory for support and hang the MoSi2 element horizontally.

2. Please put the taper part of the element bottom into the furnace chamber to avoid local overheating.

3. The lead wire should be a little longer than the linear distance between the element and bus line to avoid putting the stress to the element.

4. Please don't tighten the screw of clamps too much at one time. It can be tightened when the element heats up to high temperature because of the element's plasticity.

5. The temperature of the clip should be less than 200°C, the contact voltage between the clip and the elements less than 0.1V.

6. The distance between the lower end of the clip and the upper surface of the through brick should be more than 50mm, to avoid the radiation heat conducting to the clip.

7. To avoid damage, 170A couldn't be long time used for the element of Ø6/12mm; 300A couldn't be long time used for Ø9/18mm element.
