Product Information
Tantalum Crucible is made of high-purity tantalum metal, including seamless and welded tantalum crucible. Seamless Tantalum Crucible is made by a seamless method that will yield a product meeting the requirements of the specification. Welded Tantalum Crucible is made from a flat-rolled product by an automatic or semiautomatic fusion welding process with no addition of filler metal.
Due to its excellent corrosion resistance properties, tantalum crucible is the ideal product for melting corrosive materials. Tantalum crucibles are mainly used for the melting of corrosive materials and the growth of crystals. Pure Tantalum Crucible is available in 99.9% to 99.999% purity. All Tantalum Crucible follow ASTM.
