The advantages of molybdenum heaters

The heat resistance of molybdenum makes it possible to produce exceptionally resistant parts that will not fracture in aggressive environments at temperatures > 2000°C. Molybdenum heaters are extremely reliable and will last for a long time. Molybdenum has a low coefficient of thermal expansion and a high modulus of elasticity so that it can be used under the most difficult conditions. Compared with tungsten, molybdenum is almost twice lighter, so products made of it demonstrate greater specific strength (at t° up to 1370°C).

Disadvantages

Almost the only disadvantage is considered the high cost of molybdenum heaters. This metal belongs to rare elements of the Earth's crust, it is difficult enough to isolate in pure form, it is refractory and difficult to handle, avoid contact of silicon-molybdenum heaters with chlorine, sulfur and sulfur dioxide, as well as work at high vacuum.

Manufacturing

Molybdenum heaters can be any format in sheets and strips. They most often look like riveted band, flat, cylindrical or spiral shaped shells. They may have a bottom with a hole for venting gas (hydrogen) from the furnace space through the tube. Tolerances and parameters are according to customer's drawings. Production technology of high quality molybdenum, tungsten and molybdenum-tungsten heaters guarantees the highest heat resistance and reliability. The price depends on the format, complexity of the configuration and additional requirements stipulated in the order.

Application

For hydrogen and vacuum resistance or induction sintering furnaces, where temperatures > 2000 °C can be achieved. Melting glass and sapphire, sintering powders, growing single crystals.
