Tantalum Crucible


Tantalum crucible is an important furnace part cause of its high melting point. Due to its excellent corrosion resistance properties, Ta crucible is the ideal product for melting corrosive materials. Edgetech Industries LLC can produce tantalum parts according to the customer’s request at a competitive price.

Tantalum metal is part of the refractory metals group, which are widely used as minor components in alloys. Tantalum is a chemical element with the symbol Ta and atomic number 73. Ta is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. Also, it is highly ductile at high temperatures. They have excellent thermal and electrical conductor properties.  The melting point of 2,996°C of Ta, is the fourth highest of all metals. The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum. Its main use today is in tantalum capacitors and in electronic equipment. Such as mobile phones, DVD players, video game systems, and computers.
