This paper describes a new method of preparing Co-P spherical powder by use of reducing agent in an aqueous solution. A fixed proportion of reducing agent, complex agent and pH buffer agent was mixed into an aqueous solution with a metallic salt solution. As the result, alloy powder was obtained. At the fixed reaction temperature of 363K, the adequate condition was searched by charging the proportion of above-mentioned agents. The obtained powders were examined by SEM, TG-DTA, XRD, EPMA and ICP. Most of spherical particles were confirmed to be amorphous by XRD and SEM. Chemical analysis of thus obtained particles showed that main elements were Co and P.
