Reduction of metallic chlorides and the physical properties of the metal produced Greenius, Arnold William


This paper is a report on the Investigations of the production of metals by the hydrogen reduction of metal chlorides and on the physical properties of the metal produced. The study covers the hydrogen reduction of cobaltous chloride; crystallographic analyses of the cobalt powder produced under conditions of varying reduction temperature and hydrogen flow, and treated under various conditions of cooling and reheating; compacting and sintering of the powder under varying pressures and sintering temperatures; tensile tests on pressed and sintered cobalt bars; tests on growth of single crystals of iron and cobalt; crystallographic orientation of the iron single crystal; and Tukon hardness variation with orientation in the (001) plane of an iron single crystal.
