TA0074 Tantalum Lump

Descriptions of Tantalum Lumptantalum-lump

Advanced Refractory Metals specializes in producing high purity Tantalum Lump with the highest possible density and smallest possible average grain sizes for use in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes. Our standard lump pieces are amorphous uniform pieces in sizes ranging from 5-15 mm. Lump materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation.
