STA Type 1700, 1800 and 1900 MoSi2 heaters molybdenum disilicide heating element are high-tech products researched and developed by experts from China and abroad.
MoSi2 Heaters Molybdenum Disilicide Heating Element can quickly form a thin and adhesive anti-oxidizing layer of quartz glass (SiO2), under the high temperature oxidizing condition. If the protective layer was damaged, the element can reform a new one, so MoSi2 Heaters Molybdenum Disilicide Heating Element have a very good anti-oxidation properties, it also means that the heating element can be used on operation for a much longer time than the traditional one.
The resistivity of the MoSi2 Heaters Molybdenum Disilicide Heating Element is not changing with the time, so a new one can be installed without effecting the old one. This can result of the huge saving in furnace maintenance fee sand time as well, increase the working efficiency. This is the key point of Heaters Molybdenum Disilicide MoSi2 Heating Element being a better material and being widely used.
Any sized elements can be made according to your requirement.
We can make U, W, UL, WL, and ROD type elements
The standard diameters are: 3/6 mm, 4/9 mm, 9/18mm, 12/24mm.

MoSi2 Heaters Molybdenum Disilicide Heating Element is used in the high temperature under oxidizing atmosphere. It will form the SiO2 film which can keep the element from being melted. When the temperature of element is more than 1700°C,the MoSi2 Heaters Molybdenum Disilicide Heating Element must not be used in the temperature between 400°C and 700°C for a long time; otherwise the element will be cremated under the strong oxidizing function in the low temperature.
MoSi2 Heaters Molybdenum Disilicide Heating Element installation:
The brittleness of MoSi2 Heaters Molybdenum Disilicide Heating Element is relative more under the usual temperature, it also has plasticity under the high temperature. So you had better hang and erect vertically the "U"-shape element. If you need to erect it horizontally, please choose a support of high-temperature insulating materials. The cone-part of the element must extend inside the furnace. At first the fixture of MoSi2 power connector cant be screwed too tightly. When temperature of the element is going up, please twist it tightly again, so the element is not easily broken.
Our suggestion: please choose the specialize power connector provided by our company) The furnace top must be a good function of heat-preservation. In general, the temperature of furnace top cant be over 300C. The voltage should be low 0.1 between the power connector and the element. In order to avoid radiating heat to pass the connector, the distance is not less than 50mm between the low end of connector and the upside of the ceramic brick. The Dia.6 element cant be used of 170A for a long time. The Dia.9 element cant be used of 300A for a long time.
Notice to Furnace Operation:
To avoid high current surges which may cause damage to MoSi2 Heaters Molybdenum Disilicide Heating Element, the recommend starting procedure as following:
Small Furnace (Power 100KW) | Big Furnace (Power 100KW-500KW) | ||
Furnace Temperature .C | Voltage | Furnace Temperature .C | Voltage |
20-150 | 1/3 | 20-300 | 1/3 |
150-500 | 2/3 | 300-700 | 2/3 |
500-Working Temperature | Full | 700-working Temperature | Full |
Note: Shifting gear must be done quickly, otherwise high current surges may cause damage. |
