Laboratory Muffle Furnace Molybdenum Silicide heating elements (MoSi2) Elements with high temperature

 What is u shape mosi2 heating element?

The u shape mosi2 heating element looks like the letter “U” in English, it is durable and reliable at high temperatures.

U Shape Mosi2 Heating Element

The U shaped mosi2 heating elements are most frequently used suspended with the bottom of the “U” down. The element consists of two cold ends (Lu) and a U-shaped hot section (Le).

The cold ends are twice the diameter of the hot section and are attached by a weld. The extremities of the cold ends are metallized with aluminum to provide a low-resistance contact surface to which the electrical connections are made with flat braided aluminum straps.

U Shape Mosi2 Heating Element

These mosi2 heating elements are available in two grades: 1700 for element temperatures up to 1700 ℃ and 1800 for element temperatures up to 1850 ℃.

The assembly of U shape mosi2 heating element

Transition section (g) should be inserted inside the furnace, to avoid the case that heat can not emit and resulting in damage of the transition section.

2. When installing, it is necessary to keep certain distance between the U shape mosi2 heating element and furnace bottom (h).

3. Make sure a reasonable distance between the U shape mosi2 heating element and furnace wall.

4. The suggest surface load of 1700 type U shape mosi2 heating element and furnace wall under 1300 C furnace temperature is below 13. 5w/cm3. The suggest surface load of 1800 type U shape mosi2 heating element under 1600℃ furnace temperature is below 11. 5w/cm2. And the suggest surface load of 1850 type products under 1720 C furnace temperature is below 12 w/cm2.
