Abstract

"Evaporation rates of liquid zinc were determined experimentally within the temperature range of 450º C to 575º C and at argon pressures ranging from 730mm Hg to 130mm Hg. Extrapolated values of these rates are found to be consistent with the previously reported rates obtained by St. Clair and Spendlove at lower pressures. Between 100 microns and one atmosphere pressure rates of evaporation seem to vary according to an equation of the form W = APᴮ, where Pis pressure and, A and B are constants. Similar experiments were performed with brass powders in atmospheres of argon and helium at temperatures between 550º C and 650º C. The kinetics of sublimation of zinc from brass powders were found to be consistent with the evaporation behavior from a liquid zinc bath. The effect of various process conditions on the morphology of zinc condensed from the vapor phase was also determined"--Abstract, page iii.
