Molybdenum rod is high temperature component, molybdenum has high temperature resistance, steam down and other characteristics, so that it is often used to manufacture high temperature furnace heating and structural materials. In the production process of tungsten and molybdenum and tungsten carbide, mostly using molybdenum wire heating method produced reduction furnace and sintering furnace. These furnaces are generally reduced atmosphere or a non oxidizing atmosphere. Molybdenum can be used in hydrogen and ammonia decomposition to near the melting point, and nitrogen can be used to 2000 degrees Celsius. When it is used above 1700 degrees, the TZM alloy or molybdenum la alloy with higher recrystallization temperature and better strength can be used as heating element. Molybdenum has very good ablative properties in fused silica. It is used as a fused electrode in the glass industry. Only 7.8 grams per ton of glass molybdenum electrode is produced, and the service life can be longer than one year. In addition to electrodes, molybdenum is also used as a glass melting high temperature structural material, such as guides, tubes, crucibles, streams, and rare earth smelting rods. The use of molybdenum instead of platinum in glass fiber drawing furnace has a good effect and greatly reduces production costs.

Nuclear fuel in sintering furnace has recently been developed by molybdenum heating, with the 0.8mm diameter of molybdenum wire woven into the three-phase mesh heater, working temperature can reach up to 1800 - 2000 degrees. In addition, molybdenum and its alloys can also be used for hot isostatic pressing grate, heat shield, sintering and steaming with the boat, SmCo and UO2 sintered magnet plate, thermocouple and its protective sleeve.
