Is tantalum toxic?
Tantalum pentoxide is a colorless solid that reacts with oxidizers and can cause explosions and fire. Cases of poisoning due to exposure have not been reported, but tantalum is moderately toxic, and if processing involves cutting, melting, or grinding, high concentrations of fumes or dust may be released into the air.
What does tantalum look like?
Tantalum is a rare, shiny, gray, dense metal. It is highly ductile and can be drawn into a thin wire. Its chemical properties are very similar to those of niobium. The metal has a melting point exceeded only by tungsten and rhenium.

Why is tantalum valuable for cell phones?
Roughly two-thirds of tantalum is used to manufacture electronic capacitors, a fundamental component of smartphones and other in-demand electronics. Tantalum has contributed hugely to the miniaturization of handheld electronic devices as it allows an electrical charge to be stored in small capacitors.
Is tantalum a good conductor?
Tantalum is dark (blue-gray), dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity.
Is tantalum heavy?
Tantalum is a gray, heavy, and very hard metal. When pure, it is ductile and can be drawn into fine wire, which is used as a filament for evaporating metals such as aluminum. At high temperatures, tantalum becomes much more reactive. The element has a melting point exceeded only by tungsten and rhenium.
