Ta(Atomic number : 73)

1. Introduce – High melting point metal with high density and low coefficient of thermal expansion, resistant to acids and bases(Below 150℃, it does not react well with royal water, but at high temperatures, it will rust in high concentrations of strong acids) – Ta alloying element effects: increased strength and ductility, higher melting point(Tantalum : melting point is the highest after tungsten and rhenium) 2. Property – Corrosion resistance, ductility, machinability, acid resistance, tensile strength, thermal conductivity and electrical conductivity, excellent biocompati...
