The annealing temperature of molybdenum is a crucial factor in its applications, especially in high-temperature environments. Understanding this temperature and the variations among different types of molybdenum can help in selecting the right material for specific uses.
What is the Annealing Temperature of Molybdenum? 7 Key Facts You Need to Know
1. Standard Annealing Temperature
The annealing temperature of molybdenum is 1149°C (2100°F). This is the baseline temperature for standard applications.
2. Lanthanated Molybdenum (MoLa)
Lanthanated molybdenum can be used at temperatures up to 2000°C (3632°F). This type contains lanthanum trioxide particles that enhance resistance to recrystallization and high-temperature warpage.
3. Silicon Molybdenum Rods
Silicon molybdenum rods are recommended for furnace temperatures between 1300℃ and 1800℃. These rods are ideal for high-temperature sintering in industrial furnaces.
4. Molybdenum Crucibles
Molybdenum crucibles can withstand working temperatures above 2000°C. They are essential for applications like sapphire crystal growth furnaces, where high purity and density are critical.
5. Molybdenum Heating Elements
Pure molybdenum heating elements can operate at temperatures up to 1200ºC (2192°F) without recrystallization. TZM, a molybdenum-titanium-zirconium alloy, offers higher strength and can be used at temperatures up to 1400°C (2552°F).
6. Tungsten and Tungsten Alloys
Tungsten and its alloys are used in high-temperature applications where other materials may fail. The choice of tungsten alloy depends on factors like component parts, equipment construction, and operating temperatures.
7. Variations in Temperature Ranges
Different types of molybdenum have varying temperature ranges for their specific applications. Understanding these variations is key to selecting the right material for your needs.
