Tantalum Powder

Tantalum 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. Tantalum is also an refractory metals. 

Edgetech Industries LLC offers tantalum metal powder in a wide variety of grain sizes suitable for all capacitance ranges of tantalum capacitors, sputtering target and other applications.
