Solid-phase reduction of Cr2O3 under chemical catalytic conditions

Abstract

The kinetics of the solid-phase reduction of Cr₂O₃ with carbon under chemical catalytic action on the reacting system is studied. A significant intensification of the process in the presence of small amounts of potassium and sodium salts is established. The concepts of the catalyst action mechanism are considered and experimentally substantiated. Manufacture of iron–chromium master alloys with a restricted content of carbon can be organized at low temperatures, and they can be used in steelmaking.
