Tantalum is a PROFIT TOOL Instance— Fansteel Tantalum Coil vs. Lead Coil The 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.

Because tantalum withstands higher steam pressures, reaction time is shortened and production is increased by one-third. And the tantalum coil is permanent—with long freedom from repair or replacement. Figures and other details are available.
