Tantalum and Niobium containing powders for AM. While 3D enlarges the scope of manufacturing possibilities, the intrinsic properties of materials applied can limit the range of accessible appliions. In this context, Ta and Nb as well as new Ta and Nbbased alloy powders can serve special fields of appliion.

· Metallic Powders Company Starck Tantalum 27/04/2020· Print. As of July 1, 2020, Starck Tantalum Niobium (TaNb) will operate under the TANIOBIS brand. A subsidiary of JX Nippon Mining Metals, TANIOBIS produces highquality materials, powders, and alloys based on tantalum and niobium.
Niobium and tantalum are transition metals almost always paired together in nature. These "twins" are difficult to separate because of their shared physical and chemical properties. In 1801, English chemist Charles Hatchett uncovered an unknown element in a mineral sample of columbite; John Winthrop found the sample in a Massachusetts mine and sent it to the British Museum in London in 1734.
· Niobium, like tantalum, can act as an electrolytic valve allowing alternating current to pass in only one direction through an electrolytic cell. Niobium is used in arcwelding rods for stabilized grades of stainless steel. It is also used in advanced airframe systems.
Tantalum is sometimes, but only rarely, found uncombined in nature. It occurs mainly in the mineral columbitetantalite, which also contains other metals including niobium. It is mined in many places including Australia, Canada and Brazil. There are several complied steps involved in separating the tantalum from the niobium.

For over one decade, Firmetal is a leading supplier in the field of rare metals such as tantalum, niobium, zirconium, titanium and their alloys. It relies on Chinese abundant nonferrous metals' mine resources, bringing its superb metal processing techniques to satisfy customers' requirements for nonferrous metal materials in chemical, photoelectric, aviation and other fields.
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.
The company has discovered numerous tantalum and niobium occurrences in Colombia and Brazil with grades exceeding 25% of tantalum and 15% of niobium. These discoveries have also proven the existence of critical minerals (including rare earths) within these ores, such as scandium, neodymium, erbium, yttrium, hafnium and cerium.
