Molybdenum crucible is high purity metal molybdenum (Molybdenum, chemical symbol Mo).
The specific ingredients are as follows:
Main component: Molybdenum (Mo)
The content is usually above 99.95%, and some high-end applications even require a purity of 99.99% (ultra-high purity molybdenum).
Molybdenum ‘s high melting point (2623°C), good thermal conductivity and stable chemical properties make it an ideal material for making high-temperature crucibles.
Impurity elements (very small amount)
Although high-purity molybdenum is very pure, it usually contains trace impurities, such as Fe (iron), Ni (nickel), Si (silicon), O (oxygen), C (carbon), Al (aluminum), etc. The total content of these impurities is usually controlled within 0.01% to ensure the high temperature performance and corrosion resistance of the material.
Different types of molybdenum crucibles may involve alloys or treatments:
TZM alloy molybdenum crucible (added Ti, Zr, C): higher strength and creep resistance, suitable for more demanding high temperature conditions.
Molybdenum-lanthanum (Mo-La) alloy crucible: adding rare earth oxides to improve oxidation resistance and ductility.
