MoSi₂ Heating Element Installation Guidelines

Because MoSi₂ elements are brittle at room temperature and ductile at high temperature, careful handling is required:

General Recommendations

• Always use vertical mounting for U-type elements. If horizontal mounting is needed, use high-temperature insulating supports.

• The cone ends must extend into the furnace chamber.

• Do not overtighten the power connectors initially. Tighten again when heated to avoid breakage.

• Use matching ceramic spacers to separate the shanks.

Installation Steps

• Remove the wooden block from between the shanks.

• Insert the element through the ceramic spacer into the mounting hole.

• Push the element in until it touches the wooden block inside the furnace.

• Fill any gaps with alumina fiber.

• Install the ceramic fixture, aligning all screws in one direction.

• Once all elements are in place, install the power tracks, ensuring they do not contact the fixture to prevent short circuits.

Note: MoSi₂ rods are fragile and should be handled with caution at all times.
