MoSi2 Heating Elements
MoSi2 heating elements supplier for kilns, muffle furnaces, box furnaces and high-temperature electric furnaces, including U type and W type molybdenum disilicide elements.
MoSi2 heating elements, also called molybdenum disilicide heating elements, are used in high-temperature electric furnaces, kilns, muffle furnaces and box furnaces where stable performance in an oxidizing atmosphere is required. This category covers U type MoSi2 elements and W type MoSi2 elements.
For supplier comparison points, full RFQ data and detailed surface load guidance, see the MoSi2 heating elements supplier guide. If you are still choosing between materials, start with the SiC vs MoSi2 selection guide.

MoSi2 Heating Elements
W type MoSi2 heating elements for short furnace chambers and compact high-temperature electric furnace designs.
View detailsMoSi2 elements suit muffle furnaces, box furnaces, trolley furnaces, kilns, laboratory furnaces and other high-temperature electric furnaces, especially where the furnace runs in an oxidizing atmosphere at high temperature for long periods.
U type MoSi2 elements are the common two-shank shape for many furnace layouts. W type elements use a multi-shank shape to deliver more power where furnace height is limited. Element shape, hot zone length, cold end length, shank diameter and leg spacing should match the furnace drawing or the old element.
MoSi2 element life depends strongly on hot-zone surface load and furnace atmosphere. The values below are general design references; confirm the final design against the real furnace condition.
| Furnace temperature | Recommended hot-zone surface load | Note |
|---|---|---|
| 1400℃ | below 18 W/cm² | Lower surface load gives longer service life. |
| 1500℃ | below 15 W/cm² | Check element spacing and radiation. |
| 1600℃ | below 12 W/cm² | Confirm a clean oxidizing atmosphere. |
| 1650℃ | below 10 W/cm² | Review terminal and shank cooling. |
| 1700℃ | below 8 W/cm² | Reserve power supply voltage for ageing. |
Avoid continuous operation at 400-700℃: in this range MoSi2 can suffer strong low-temperature oxidation (pesting) and may powder.
For a replacement, send photos of the old element and terminals, the element dimensions and any voltage, power or resistance records. For a new furnace, send furnace type, chamber size, target and peak temperature, atmosphere and quantity so the technical team can review the specification.
FAQ
Henan Lasting supplies U type and W type MoSi2 heating elements. Send the furnace drawing or a photo of the old element to confirm the element shape, hot zone, cold end, shank diameter and leg spacing.
Recommended hot-zone surface load is below 18 W/cm² at 1400℃, below 15 W/cm² at 1500℃, below 12 W/cm² at 1600℃, below 10 W/cm² at 1650℃ and below 8 W/cm² at 1700℃.
In the 400-700℃ range MoSi2 can suffer strong low-temperature oxidation, known as pesting, which may cause the element to powder, so continuous operation in this range should be avoided.
Provide furnace type, chamber size, target temperature, atmosphere, element shape (U or W), hot zone, cold end, shank diameter, leg spacing, voltage, power, resistance and quantity. Drawings or installed-element photos help confirm the shape.
U type elements are the common two-shank shape for many furnace layouts, while W type elements use a multi-shank shape to provide more power where furnace height is limited.
