A STUDY OF EQUILIBRIUM IN THE REDUCTION OF BERYLLIUM OXIDE WITH CARBON AT HIGH TEMPERATURES

Abstract

The equilibrium in a beryllium oxide-carbon system is studied by the manometric method in the range 1400-2000 C. Equilibrium pressure can be reached only in the temperature range 1700-1950 K. The reduction products at these temperatures contained beryllium carbide and unreacted beryllium oxide and carbon. At higher temperatures the pressure of the carbon monoxide at first reaches a maximum, and then begins to decrease sharply, never reaching a definite value. The dependence of the change in free energy on temperature was of a linear nature. The conclusion is made that in the 1700-1950 K interval an equilibrium state exists corresponding to the reaction whereby 1/2 Be2C (solid) and CO (gas) are the products. (Author)
