Here are three cutaway drawings of Tantalum Capacitors: A Tantalum SMD capacitors, Tantalum wet axial silver cased capacitor and a Tantalum wet axial tantalum case. Might help in demonstrating the different materials used in making tantalum type capacitors. Note these are three different types of tantalum capacitors from three different references, tantalum capacitors are made by many different methods and companies.
