Molybdenum has the high purity, good high temperature resistance, low vapor pressure characteristics, so it is often used to make high-temperature furnace heating elements and structural materials. Molybdenum and tungsten carbide in the production process, most of the way by producing molybdenum Continuous Twisted heat reduction furnace and sintering furnace, part of the continuous sintered iron molybdenum rod was also used for heating element heated row, row heated molybdenum to molybdenum rod hook hanging on both sides of the stove. Such furnaces generally reducing atmosphere or a non-oxidizing atmosphere, hydrogen and decomposition of ammonia in the molybdenum wire can be used to nearly the melting point, the nitrogen can be used to 2000℃. Higher than 1700℃ using, we can use a higher recrystallization temperature, strength and better TZM alloy or moly alloy for heater.
Molybdenum in molten quartz has very good ablation resistance, in the glass melting industry for power electrodes, each ton of glass electrode lost only 7.8 grams of molybdenum, the useful life of more than a year. In addition to electrodes, the molybdenum is also used for glass melting temperature structural materials, such as the slot, tube, crucible, and export of rare earth smelting flow stirring rod. Molybdenum on behalf of the platinum in the use of glass fiber furnace works well, greatly reducing production costs.
Newly developed nuclear fuel sintering furnace with molybdenum heating network, with Ø0.8mm molybdenum wire mesh woven into three-phase heater temperature up to 1800-2000℃. In addition, molybdenum and its alloys also can be used for hot isostatic pressing furnace frame, insulation, sintering and coating of the material steam boat, SmCo magnets and uranium dioxide sintered plate, thermocouple and protective cover tubes.
