Tantalum has a melting point of 3,017°C, a density of 16.6 g/cc, and a vapor pressure of 10-4 Torr at 2,590°C. It is metallic grey-blue in color with strikingly similar chemical properties to niobium. It is mainly used to make surgical implants due to its non-toxic nature. It is also used as a capacitor for electronics and may be alloyed with other metals to add strength and durability.

Stanford Advanced Materials (SAM) is a leading manufacturer and supplier of high purity Tantalum Evaporation Materials and a wide variety of evaporation materials. We offer our evaporation materials in powder and granule form. Customized forms are also available upon request.


Tantalum (Ta) is a dark blue-gray metal that is very heavy, ductile and hard and has high corrosion resistance. Tantalum is especially resistant to chemicals at temperatures below 150 °C and can only be dissolved with hydrofluoric acid.

High purity evaporation materials play a huge role in deposition processes to ensure high quality deposited film. Stanford Advanced Materials (SAM) specializes in producing up to 99.95% purity tantalum evaporation materials using quality assurance processes to guarantee product reliability.
