Tantalum (Ta) is a refractory metal. Tantalum is quite soft compared to tungsten or even molybdenum.. The density and melting point of tantalum lies between that of tungsten and molybdenum.. Tantalum is often used in capacitors or other electronic devices and is often also used to alloy other metals. Its high corrosion resistance is useful in chemical reaction pipes and vessels such as vacuum
