Effect of Boron on the Structure and Composition of Cobalt Silicides

The system Co -- Si -- B is promising for development of new soft magnetic materials. We studied the effect of boron on the structure and composition of cobalt silicides during solid-phase reaction of powders of the starting components under a 3·10^sup -3^ Pa vacuum in the temperature range 200°C to...

Description
Summary:The system Co -- Si -- B is promising for development of new soft magnetic materials. We studied the effect of boron on the structure and composition of cobalt silicides during solid-phase reaction of powders of the starting components under a 3·10^sup -3^ Pa vacuum in the temperature range 200°C to 1300°C for boron content from 0.5 mass% to 7.7 mass% by differential thermal analysis, metallographic analysis, x-ray analysis, and electron-probe microanalysis. We established that boron is not soluble in cobalt silicides. Formation of ternary chemical compounds is typical for the Co -- Si -- B system.[PUBLICATION ABSTRACT]
