AMUCT: 'It Is shom that the mathematical method for planning experiments (Wallmov,
V. V., "Statistical mothods for describing chosaLcal and mt&UurgIc&L processes",
Ketallurgizdat, 1963) may be used In determining optimum conditions for production of
tantalum from the pentachloride. Rectified tantalum pentachlorLde was used contalning
