MoSi2 Small Electrical Heating Element for Lab Furnace
mosi2 heating element is a kind of resistance heating element made from Molybdenum Disilicide.
It can be used in air and various gases environments. Working temperature of MoSi2 heating
element is 1300C to 1800C. It has the characteristics of high temperature resistance, oxidation resistance, corrosion resistance, heating fast, long service life, high temperature low distortion, easy installation and maintenance, excellent chemical stability, which has been widely used as heaters in high temperature furnaces and kilns of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacture and chemical industry field.
Types of mosi2 heating element
1. According to temperature: 1700C and 1800C
2. According to Shape: U, W, I, UL, WL, Spiral types.
mosi2 heating element standard size
(Hot zone dia / Cold zone dia)
3/6mm, 4/9mm, 6/12mm, 9/18mm, 12/24mm.

Installation of mosi2 heating element
) Vertically hanging
Under normal temperature, MoSi2 element is very brittleness, while under high temperature, it is plasticity, so the better way to install U Shape element is to hang it vertically from the furnace top through the support clamping chuck. The aim of such way is to avoid putting the mechanical stress directly to the element heat-generating end; otherwise the element will easily be broken.
2) Support clamp
Support clamp are applied to 9/18 and 6/12 two kinds of elements respectively. The support clamp supports the whole weight of the element and the position of the element is also determined by it, therefore, it must be installed carefully to assure the element vertically hung. In order to prevent the element from being over heated locally, the taper part of the element lower end must put into the furnace chamber.
mosi2 heating element Application:

Heating elements | 1700 type | Element operating temperature 1700℃ is acceptable | Le Φ 6-12W type/U type/L type/all kinds of hetero type / stripe shape | high temperature electric resistance furnace |
1800 type | Element operating temperature 1800℃ is acceptable | |||
1800J type | Element operating temperature≥1800℃ | Le Φ 3-12W type | Special,high temperature and high-power electric resistance furnace | |
1800T type | Element operating temperature≤1800℃ | Le Φ 3-12W type U type | Not oxidized special air high temperature electric resistance furnace |

Furnace temperature | Voltage | furnace temperature℃ | Voltage |
20-150 | 1/3Operating Voltage | 200-300 | 1/3Operating Voltage |
150-500 | 2/3Operating Voltage | 300-700 | 2/3Operating Voltage |
500-operating temperature | The Whole-Operating Voltage | 700-Operating temperature | The whole-Operating Voltage |
It should not take a long time when shifting gears. Otherwise it easily causes the electric current
shocking to break the electrical equipment.
Element Replacement
If there is a damaged part found in the process of operation, the first thing you should do is determine its location and get all the combination elements ready. After that, you should separate the wire the damaged element clipped to from the screw which is connected to the generatrix. Then remove the remained refractory wool and pull out the refractory stoppers. Insert the new combination elements into the furnace from its roof. Connect all the wires and get the refractory wool filled, and finally raise the temperature.
