2011 MoSi2 heating elements (ISO9001:2000) (HOT)
MoSi2 heating element is a kind of resistance heating element basically made of high pure Molybdenum Disilicide .In oxidizing atmosphere,on the surface of MoSi2 element owing to the high temperature combustion a layer of compact quartz protective film is formed to prevent MoSi2 from continuously oxidizing .In oxidizing atmosphere , MoSi2 heating element can usually make use of furnace temperature from 1300 to 1800. It is extensively used in the industries of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacture, etc.
The product includes series 1700 grade, 1800 grade. Packaging is available in U shape, W shape, Straight shape (X shape) and bend shape (L shape) and the special shape etc. The dimension ranges from 3/6, 4/9, 5/10, 6/10, 6/12, 6/14, 7/14, 8/16, 9/18 to 12/24mm.

Cracked and Partially Burnt Ammnia | 1400 | 1450 |
It can be widely used in such applications as sintering and heat treatment on ceramics, magnet, glass, metallurgy, refractory, etc.
Notice to Furnace Operation:
To avoid high current surges which may cause damage to MoSi2 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. | |||
