W-shape MoSi2 Heating Element
Oxygen-resistance under high temperature: in oxidizing atmosphere, a layer of compact quartz protective film is formed on the surface of element owing to the high temperature combustion, which prevent MoSi2 from oxidizing more. When the element temperature is higher than 1700 C, the film becomes melting. It's not suitable for long time use in the temperature range of 400-700C, otherwise, the element will be powdering for the strong oxidation under low temperature.
MoSi2 heating element is a type of resistance heating element composed of high purity Molybdenum Disilicide.When heated toa high temperature in an oxidizing atmosphere,a layer of compact quartz qlass forms on the surface of the element which withstands oxidation.In an oxidizing atmosphere,its maximum temperature canreach1800 and its applicable temperature is 500~1700C. It can be widely used as heating elements in high temperature furnaces for a variety of industries including ceramics, magnets, glass metallurgy, refractory and many others.
U-L Shape MoSi2 Heating Elements
MoSi2 heating element can usually make use of furnace temperature from 1300C to 1900C. It is extensively used in the industries of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacturer etc. It is an essential ideal element when the products are sintering in the high temperature.
SPK Customized MoSi2 heating element
MoSi2 resistive heating element is a high temperature resistant and anti-oxidation resistance heating element based on molybdenum disilicide. When used in high-temperature oxidizing atmosphere, a layer of bright and dense quartz (SiO2) glass film is formed on the surface, which can protect the inner layer of the silicon molybdenum rod from oxidation, so the silicon molybdenum rod element has unique high-temperature oxidation resistance.
Under oxidation atmosphere and the maximum service temperature is 1800 �¢??, the resistance of the silicon molybdenum rod electric heating element increases rapidly with the increase of temperature, and the resistance value is stable when the temperature is constant. Under normal conditions, the element resistance does not change with the length of service time, so the new and old silicon molybdenum rod heating elements can be mixed.

DB ( Dumbbell ) Type Silicon Carbide Heating Element
Silicon carbide (SiC) Heating Element is a kind of non-metal rod or tube shape high temperature electric heating element.It is made of selected super purity green hexagonal silicon carbide as main material, which is made into blank and silicon crystal under high temperature of 2400�ºC. In oxidizing atmosphere, its service temperature can reach 1450�°C and continuous use life can reach 2000 hours.
The Dumbbell style elements, with the enlarged cold ends, were one of the earliest designs of the heating elements, which were originally made oversized to increase the cold end cross section, lowering electrical resistance so as to lower the operating temperature of the cold ends. Modern Dumbbell elements, by contrast, all employ an advanced technology to keep the terminal ends cool by virtue of the decreased resistivity of the lower resistance of the material of the cold ends in the manufacturing process. Therefore, oversized cold ends are no longer necessary. Non-dumbbell or ED type elements can substituted for Dumbbell elements.
W Type SiC Heating Elements
Silicon Carbide Heater Advantages
1. Withstands as high as 1500�°C (surface temperature).
2. Various shapes, like Rod shape, U shape, W shape, Single Spiral & Double Spiral shape, are available to meet your demand.
3. Large size range.
4. Generates high heat output per unit surface area.
H Type Silicon Carbide Rod
H-shaped silicon heating element is manufactured by taking two carefully-matched SiC rods and welding a thickened silicon carbide bridge. This element provides for wiring both tail ends from one side of the furnace. The tail ends of the cold ends are metallized with aluminum, which can provide a low-resistance contact surface to the aluminum connection straps and clamps.
Since H-shaped silicon heating element is composed of two ED silicon heating elements sharing a cold end, it can be connected by the power cord at one end of the furnace. The surface temperature of heating part is 1500. It is mainly used in kilns with high furnace temperature and high temperature uniformity. Its characteristics are electricity saving and long service life.
In addition, a furnace with an energy saving structure can be built because the number of heating element holes on the furnace can be reduced compared with the H types. These elements are widely used as high-temperature heat sources for electric furnaces and for the firing of ceramic capacitors, ferrites and other electronic components.
