Description

The e.m.f. measurements were made on the cell,<BR>(This article is not displayable. Please see full text pdf.) <BR>\oindentby using a Co-B alloy containing about 20 at%B. The e.m.f. values were used in calculation of the thermodynamic properties of Co3B and Co2B. The calculated thermodynamic properties are as follows:<BR>(This article is not displayable.
