Abstract
"The purpose of this investigation is to determine the vapor pressure or volatility of the sulfides of the following metals by Langmuir's method: a) Zinc b) Cadmium c) Mercury d) Manganese e) Tin f) Lead g) Arsenic h) Antimony i) Molybdenum J) Iron k) Cobalt l) Nickel m) Copper n) Silver o) Calcium p) Aluminum.
The relation of this property to the position of the metals in the periodic table will be discussed, thus the vapor pressure or volatility of the remaining metals can be predicted as to the order of magnitude if the law of periodicity holds.
The possible application of such data in vacuum reduction, separation, and dissociation of metallic sulfides will also be discussed; illustrative examples of such applications are carried out in the following experiments:
a) Vacuum reduction of molybdenum sulfide with silicon
b) Vacuum reduction of molybdenum sulfide with tin
c) Vacuum reduction of iron sulfide with silicon
d) Vacuum reduction of zinc sulfide with calcium carbide
e) Vacuum separation of zinc sulfide and lead sulfide
f) Vacuum separation of zinc sulfide and manganese sulfide
g) Vacuum dissociation of silver sulfide "--Introduction, pages 5-6.
