Mechanical performance parameters of tantalum crucible
The mechanical performance parameters of tantalum crucible mainly include density, hardness, thermal expansion coefficient, etc.
Density: The density of tantalum crucible is relatively high, generally ranging from 16.67g/cm³ to 17.10g/cm³. This density characteristic enables tantalum crucible to maintain good stability and durability during manufacturing and use.
Hardness: The hardness of tantalum crucible is moderate, and the hardness value is low, such as 140HV, which makes it difficult for tantalum crucible to crack or deform during processing and use, and is also conducive to various fine processing operations.
Thermal expansion coefficient: The thermal expansion coefficient of tantalum crucible is very small. This feature enables tantalum crucible to maintain good dimensional stability in high temperature environment, and is not easy to deform or crack due to thermal expansion and contraction, thereby ensuring its reliability and durability in high temperature experiments or smelting processes.
