The body of the heating element is composed of a dense ceramic material, which is made of high-purity MoSi2 sintered at high temperatures and 

has a high melting point and good oxidation resistance.The molybdenum core is coated with quartz glass. The elements become nearly liquid as 

they approach the maximum temperature,and the glass surface reacts with the oxygen in the air atmosphere to form a renewed coating of protective 

glass on the element surface.These materials have good electrical conductivity and thermal stability and can efficiently transfer electrical energy into

 thermal energy.

Advantages

Mosi2 heating elements have good stability and mechanical strength at high temperatures, and can maintain long-term stable performance at high 

temperatures. In addition, Mosi2 heating elements also have excellent oxidation resistance and corrosion resistance, so they have along service life

 when used at high temperatures.

Applications of MoSi₂ Heating Elements

Mosi2 heating element can be widely used in such applications as sintering and heat treatment of ceramics, magnet, glass, metallurgy, refractory

 etc.Especially, Mosi2 heater is the requisite heating element in heat sintering process of high-performance ceramics, high rank synthetic crystalloid, 

sophisticated structure cermets, glass fiber, optical fiber as well as high rank alloy steel, and it is the best environment-protecting product in the

 heating area in the 21st Century.

1. Suitable for the intermittent high temperature furnace with frequent heating-cooling.

2. Suitable for dental furnace with no discoloration, Rapid thermal cycling applications.

3. Suitable for Sintered products with strict thermal field of the environment.

Characteristics

Physical Characteristics

Oxygen-resistance under high temperature:in oxidizing atmosphere,a layer of compact quartz (SiO2)protective film is formed on the surface of element owing

 to the high-temperature combustion, which prevent Mosi2 from continuously oxidizing.

When the element temperature is higher than 1700 °C (3092 °F), the sio2 protective film will be fused because its fusing point is 1710 ℃ (3110℉) and the sio2 

is fused into molten dropa owing to the action of its surface extension,which cause losing its protective ability.In the oxidizing atmosphere, when the element is 

continuously used, the protective film forms again.The MoSi2 heating element must not be used in the temperature between 400 °C (752 °F)and 700 °C (1292 °F)

 for a long time, otherwise the element will be cremated under the strong oxidizing function in the low temperature.

Indications in different atmospheres.

a. CHOOSE THE RIGHT SIZE AND SHAPE: Choosing the right size and shape is very important when selecting a Mosi2 heating element.

Factors to consider include the size of the heating chamber or furnace, the required temperature of the furnace, and even heat distribution.

b. Pay attention to the rated power and voltage of the heating element: The rated power and voltage of the Mosi2 heating element should 

also match the furnace to ensure compatibility with the power supply and control system. Overloading a heating element can cause it to fail

 prematurely, while undersizing a heating element can lead to insufficient heating.

c. Choosing the right heating controller: Choosing the right controller is also very important for the efficient operation of the Mosi2 heating 

elements. Choosing the correct controller depends on the temperature range required, the rate of heating, and the level of precision and control

 required.
