A rare nonmetallic element found in certain minerals, as tantalite, samarskite, and fergusonite, and isolated as a dark powder which becomes steel-gray by burnishing. Symbol Ta. Atomic weight 182.0. Formerly called also tantalium.
hard ductile gray-white acid-resisting metallic element found combined in rare minerals
A rare metal of silver white colour having excellent corrosion resistance and a high melting point. It is widely used for chemical process equipment and specialised aero-space and nuclear applications.
a hard gray lustrous metallic element that is highly corrosion-resistant; occurs in niobite and fergusonite and tantalite
a polarized capacitor like an (aluminum) electrolytic, I saw that but I don't understand why anyone would have suggested it
A by-product of tin processing, this refractory metal is used as a barrier to corrosion of chemical processing and carbide cutting tools, and still-growing use as electronic capacitors and filaments. Melts at 2415 degrees Fahrenheit.
A rare, very hard, heavy, gray metallic element that is exceptionally resistant to corrosion and chemical attack below 150°C. It is used to make light-bulb filaments, electrolytic capacitors, lightning arresters, nuclear reactor parts, and some surgical instruments.
Tantalum (IPA: ), formerly tantalium (IPA: ) is a chemical element in the periodic table that has the symbol Ta and atomic number 73. A rare, hard, blue-gray, lustrous, transition metal, tantalum is highly corrosion-resistant and occurs in the mineral tantalite.
