làntalum is a PROFIT TOOL· Instance— Fansteel Tantalum Coil vs. Lead Coil T h e tantalum coil at the right was designed for the same work as the base metal coil above-boiling a mixture of sulphuric and hydrochloric acids. T h e heating area of the tantalum coil is only 1/18th that of the base metal coil.
