Vacuum refinning cooper blister to remove antimony
Abstract
A research on kinetics of antimony evaporation from molten copper blister was made in a vacuum induction melting (VIM) furnace at temperatures of 1 473 and 1 523 K, and operating pressures of 8 - 133 Pa. The evaporation rate of Sb was found to be first order with respect to your content in the melt. The overall mass transfer coefficient of antimony evaporation from cooper blister are from 1,82×10-5 ms-1 to 3,43×10-5 ms-1 at 1 473 K (8 Pa) - 1 523 K (133 Pa).
