Tantalum and Its Alloy Target
Assay of Ta:≥99.95%，99.99%
Tantalum carbide,Chemical formula TaC,Molecular weight 192.96,Carbon content 6.224%,Density 14.3g/cm3 ,Melting point 3875ºC,Boiling point 5500ºC.Tantalum carbide is brown powder with high chemical stability and favorable hightemperature character.It is hard and heavy.Fine TaC powder is an important cermet material.The cutting tool made of it,having a hardness similar to the diamond,can offer resist high temperature lower than 3800ºC .As an additive of fine crystalline grain to WC hard alloy,TaC powder can improve notably the performance of alloy .
Uses in the powder metallurgy, the cutting tool, fine ceramic, chemistry gas phase deposition, the flinty antifriction metal cutting tool, the tool, the mold and the wear resisting anticorrosion structural element chemical additive, enhances the alloy toughness. The tantalum carbide sintered body demonstrates golden yellow, may make the wristwatch ornament. In addition may apply in the flinty thin film, the target material, the welding material, the spray coating material and so on.
