STA MoSi2 heating element is a resistance generate-heating component made from MoSi2 or the basic material. It is used in high temperature under the oxidizing atmosphere, it looks like glass in its surface and form a light SiO2 glass film which can protect the element not to be oxidized. So this kind of element has unique effect for resisting oxidization in the high temperature. It is used to the highest temperature up to 1850C during oxidizing atmosphere.
MoSi2 heating element can usually make use of furnace temperature from 1300C to 1850C. It is extensively used in the industries of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacture, etc.. It is an essential ideal element when the products are sintering in the high temperature.

MoSi2 Heater Molybdenum Disilicide Heating Elements 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 Heater Molybdenum Disilicide Heating Elements 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.
Notice to Furnace Operation:
To avoid high current surges which may cause damage to MoSi2 Heater Molybdenum Disilicide Heating Elements , 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. | |||
