Tantalum and Niobium | Mining | SGS

Tantalum and niobium processing can be difficult because the minerals are brittle, heavy and typically highly intergrown with sulfide and other oxide minerals. SGS has contributed to many tantalum projects over the years and can bring an integrated suite of services to tantalum and niobium exploration or development projects.

Tantalum (Ta) - Chemical properties, Health and ...

It is rarely used as an alloying agent because it tends to make metals brittle. Tantalum resist corrosion and is almost impervious to chemical attack, for this reason it has been employed in chemical industry, e.g. for heat exchanger in boilers where strong acids are vaporized.

Tantalum end uses - globaladvancedmetals

Tantalum is a critical component in the manufacture of state-of-the art semiconductors. Using the physical vapor deposition (PVD) process, tantalum is "sputtered" onto semiconductor substrates to form a thin film diffusion barrier to protect the copper interconnects. Tantalum sputtering targets are used in a variety of other products, including ...

Tantalum - Element information, properties and uses ...

Tantalum is relatively rare: it's the fiftieth commonest element in the earth's crust. There are only 40 miligrams of the stuff in a cell phone, but with there currently being about two phones for every three people on Earth, that's still a lot of tantalum. Last year more than two-and-a-half million kilograms were used, two thirds of that in ...

Tantalum capacitor - Wikipedia

A tantalum electrolytic capacitor is an electrolytic capacitor, a passive component of electronic circuits.It consists of a pellet of tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by liquid or solid electrolyte as a cathode.Because of its very thin and relatively high permittivity dielectric layer, the tantalum capacitor distinguishes ...

Niobium (Columbium) and Tantalum Statistics and Information

Niobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given in 1801, and niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in 1950. Niobium in the form of ferroniobium is used worldwide, mostly as an alloying element in steels and in superalloys.

Tantalum Coating - Thermo-Chemical Diffusion Process

Tantalizing is a thermo-chemical diffusion process used to provide corrosion resistance to metals in highly corrosive environments. The process puts a uniform layer of tantalum onto the surface of the substrate, allowing it to act with the same properties as pure tantalum metal.

How Tantalum Is Mined | Sciencing

How Tantalum is Mined. Tantalum comes from the processing and refining of tantalite. Tantalite is the common name for any mineral ore containing tantalum. Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum.
