Tantalum Crucible is well known for its corrosion resistance to acids. It also is immunne to the attack by aqua regia at temperatures below 150 degree Celsius. It is very ductile and can be easily fabricated. It is also a good conductor of heat and electricity. It forms a protective oxide layer to combat further reactions by corrosive materials. It has a high melting point and strength. It is extremely inert, except towards hydrofluoric acids and sulfuric acids. It is also prone to corrosion by alkaline solutions.
