A. Overview of Molybdenum Disilicide Heater:
1.Molybdenum Disilicide Heater is a kind of resistance heating element basically made of high pure Molybdenum Disilicide.
2. Shape: W Type
3. Max Temperature: up to 1800℃(under Oxidizing atmosphere) ,Applicable Temperature: 500-1700℃
4. Application: sintering and heating treating of ceramic, magnet, glass, metallurgy, refractory, ect.
Silicon molybdenum rod electric heating element products are widely used in the fields of metallurgy, steel making, glass, ceramics, refractory materials, crystals, electronic components, semiconductor materials research and production, especially for high-performance precision ceramics, high-grade artificial crystals, Production of precision structural cermet, glass fiber, optical fiber and high-grade alloy steel.
The silicon carbon rod is a non-metallic heating element. It is made of high-purity green hexagonal silicon carbide as the main raw material and recrystallized at a high temperature of 2200°C. The normal use temperature can reach 1450°C. Under reasonable use conditions, it can be used continuously for more than 2000 hours. When used in air, no protective atmosphere is required. Suitable for all kinds of electric furnaces and electric kilns.

Molybdenum Disilicide MoSi2 Heating Element use and maintenance:
1. MoSi2 heating element belong to Metal ceramic material. They are hard, crisp and low impact strength at room temperature .Therefore to be careful to avoid damage during transport and installation.
2. When MoSi2 heater continuously operate in an oxidation atmosphere, the surface temperature of 1700 type should not exceed 1700 ° C,1800-type should not over 1800 ℃ and for intermittent use,1700 type-element should not over 1650 ° C,1800type-element cannot exceed 1750 ℃.
Furnace dryness
New or old furnace not used for a long time needs to be dried before using. Generally, the drying temperature is 100-200℃.
However, if the element is used for a long time under the low temperature, it will cause the low-temperature oxidation.
For little furnace, the drying time is short, the influence of several drying hours is little, but for large furnace, which need to be dried for a long time, you had better open the furnace door to ventilate well. you can open the furnace door ajar with the temperature increment and completely close until the temperature reach 1000℃ above.
Furnace start
If the furnace dry out has been completed or does not need drying, it has to rise its temperature. In order to avoid the oversized electric current impact and cause the electrical equipment overload;
Please go up the furnace temperature according to the following table.
