In alloy material research, molybdenum crucible is a very critical experimental tool, especially suitable for high-temperature smelting, controlled purity preparation, trace alloy element addition and thermal property testing. Its excellent high-temperature performance and chemical stability make it an irreplaceable experimental auxiliary equipment for studying refractory alloys, active metal systems, rare earth metal alloys, and ultra-high purity alloy materials.
- The key role of molybdenum crucible in alloy material research
- High temperature alloy melting container
Molybdenum crucibles can withstand temperatures above 2000°C and are suitable for the preparation of:
High melting point alloys (such as W-Ni-Fe, Ta-based, Re-based systems)
Refractory rare earth alloys (such as Nd-Fe-B, Gd magnetic materials)
Special alloys for aviation/nuclear applications (such as Ti-Al, U-Mo, etc.)
Ensure that the melt is uniform, the reaction is complete and there is no pollution.
- Trace alloying element addition and impurity control test
High purity molybdenum itself does not release impurities and does not react with most alloying elements:
Suitable for trace doping (such as adding micro-alloying elements such as B, Zr, Nb, etc.)
It can ensure that the doping elements are not adsorbed or reacted by the crucible wall
Ensure experimental repeatability and element content control accuracy
- Phase diagram determination and thermal analysis experiments
In equipment such as DSC (Differential Scanning Calorimetry), TG-DTA, etc., molybdenum crucibles can be used for:
Alloy melting point determination
Phase change thermal analysis
Solid-liquid equilibrium curve drawing
Accurately record thermal effects without interfering with the thermal response of the alloy system.
- Study on alloy behavior under controlled atmosphere conditions
Molybdenum crucible is suitable for:
Vacuum system (high vacuum sintering, electron beam melting)
Inert atmosphere (argon, helium protection)
The following stable working conditions can be used for research:
Alloy oxidation and volatilization behavior
Gas dissolution/precipitation behavior (such as hydrogenation-dehydrogenation process)
Intermetallic Stability
