Tantalum Cylindrical Crucible

Goodfellow's range of Tantalum Cylindrical Crucibles are high-temperature crucibles made from tantalum metal. Tantalum has excellent corrosion resistance and high-temperature strength, making it an ideal material for crucibles used in applications like vacuum melting and sintering of reactive metals. We offer Tantalum Cylindrical Crucibles in 7 different sizes to accommodate different material quantities and processing needs. These crucibles are commonly used in laboratory and industrial settings for applications like melting titanium alloys or sintering tungsten carbide powders.
