Molybdenum has a very high melting point (2620°C). In refractoriness, it is second only to tungsten, rhenium, osmium, iridiu. Molybdenum retains strength at temperatures up to 2000 °C, it is demanded in those industries where it is necessary to withstand considerable mechanical and thermal loads. To 1370 °with its relative thermal strength is higher than that of tungsten. Molybdenum is characterized by minimum thermal expansion coefficient, high elastic modulus, excellent corrosion resistance, allowing it to be used in the most demanding conditions, including in aggressive environment.
The disadvantage is the high production cost of molybdenum heaters. Because of the significant hardness and refractoriness molybdenum difficult technological processing. Production it time-consuming, and obtaining it in its pure form is quite difficult. Under normal conditions, it is rigid and not very technological material.
Molybdenum heaters are made from plates and strips of high-quality molybdenum in a variety of sizes. Tolerances and parameters according to customers ' drawings. Most often, the heaters look like riveted shell flat ribbon, cylindrical, or spiral shape. The bottom is provided with a hole for gas release of hydrogen from the furnace chamber. The latest production technology guarantee maximum reliability and resistance heaters. The price depends on the size, complexity configuration and additional requirements of delivery.
Molybdenum heaters are used as resistance elements in the design of the hydrogen and vacuum furnaces, induction furnace sintering. Designed to achieve temperatures greater than 2000 °C. In such furnaces is made by sintering of powder materials, melting the sapphire glass, the growing of single crystals.
