Tantalum is a very hard, ductile, lustrous, blue-gray transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as components of strong high-melting-point alloys.

2024年12月24日 · Tantalum (Ta), chemical element, bright, very hard, silver-gray metal of Group 5 (Vb) of the periodic table, characterized by its high density, extremely high melting point, and excellent resistance to all acids except hydrofluoric at ordinary temperatures.

Tantalum is sometimes, but only rarely, found uncombined in nature. It occurs mainly in the mineral columbite-tantalite, which also contains other metals including niobium. It is mined in many places including Australia, Canada and Brazil.

2024年5月28日 · Tantalum is a chemical element with the symbol Ta and atomic number 73. It is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. Tantalum is important in electronics, so you encounter it in capacitors and high-power resistors. Other uses include camera lens coating and hip replacements. Discovery, Naming, and ...

2023年10月13日 · Tantalum is a transition metal element with the symbol Ta. It is a rare and dense metal known for its exceptional corrosion resistance and high melting point. It exists in the geology as a range of ores and is not present in the metallic state in nature.

Tantalum is a rare, shiny, gray, dense metal. It is highly ductile and can be drawn into a thin wire. Its chemical properties are very similar to those of niobium. Tantalum is highly corrosion resistant due to the formation of an oxide film. It is an excellent conductor of heat and electricity.

Tantalum is used to make various alloys to enhance strength, melting points, boiling point and ductility of the metals. super alloys of tantalum are used to make nuclear reactors, components of jet engine and missile parts.

2020年1月2日 · Tantalum is a blue-gray transition metal with element symbol Ta and atomic number 73. Because of its hardness and corrosion resistance, it is an important refractory metal and is widely used in alloys. Discovery: Anders Ekeberg in 1802 (Sweden) showed that niobic acid and tantalic acid were two different substances.

Tantalum is used to make electrolytic capacitors and vacuum furnace parts, which account for about 60% of its use. The metal is also widely used to fabricate chemical process equipment, nuclear reactors, aircraft, and missile parts. Tantalum is completely immune to body liquids and is a nonirritating material.
