Tantalum crucible

Physical properties for Tantalum 

       Tantalum is dark (blue-gray), dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity. The metal is renowned for its resistance to corrosion by acids; in fact, at temperatures below 150 °C tantalum is almost completely immune to attack by the normally aggressive aqua regia. It can be dissolved with hydrofluoric acid or acidic solutions containing the fluoride ion and sulfur trioxide, as well as with a solution of potassium hydroxide. Tantalum's high melting point of 3017 °C (boiling point 5458 °C) is exceeded among the elements only by tungsten, rhenium and osmium for metals, and carbon.

Feature for tantalum crucible
       Tantalum can be used as a substitute for stainless steel in the production of various inorganic acids.Tantalum crucible can be used in chemical containers or vacuum coating.Tantalum has a wide range of applications due to its characteristics.In the chemical, electronics, electrical and other industries, tantalum can replace tasks that used to be undertaken by precious metal platinum, resulting in much lower costs.
