The maximum operating temperature for molybdenum varies depending on its application. For general purposes, molybdenum has a high melting point of up to 2800°C, allowing it to be used in high-temperature environments. In the context of KINTEK furnaces, which are designed for maximum operating temperatures in the range of 1500-1800°C, molydisilicide heating elements are used as they can quickly attain and sustain high temperatures and have an affinity for oxidizing atmospheres. These elements have a maximum temperature that is always 100°C higher than the maximum rated furnace temperature. For example, 1800°C elements are used in 1700°C furnaces.
Molybdenum resistors can withstand temperatures up to 1650°C and are ductile enough to be drawn into wire for resistor windings. They require supports (insulators) made of magnesia or zirconia and cannot be operated in air or exposed to reactions with silicon and carbon. A hydrogen atmosphere is usually used for their protection.
Lanthanated molybdenum (MoLa) is recommended for use up to a 2000°C element temperature and has excellent resistance to recrystallization and high-temperature warpage. It contains lanthanum trioxide particles that form a "stacked fiber" grain structure.
Molybdenum crucibles are used in high-temperature environments above 2000°C, such as sapphire single crystal growth furnaces and quartz glass smelting furnaces.
Silicon molybdenum rods, commonly used in metallurgy, glass, ceramics, magnetic materials, refractories, and furnace manufacturing, have a furnace temperature range of 1300-1800°C.
It is worth noting that molybdenum disilicide, although not specifically mentioned as an operating temperature, has mechanical properties similar to ceramic products and can be brittle and easily broken at high temperatures. Proper installation and handling can help avoid these issues.
