Prepared specimens of 97% Ce with 2.9% Nd and Pr were used in determining the volume of hydrogen combined with Ce. The hydrogen content was determined by evaluation of the amount of hydrogen absorption (the drop in pressure of the system), by weighing the metallic Ce, and by determination of the volume of hydrogen recovered in hydride dissolved in dilute hydrochloric acid. The order of error was plus or minus 2% of the determined value. After careful puriflcation of the initial material, the hydridation of the metallic Ce takes place at room temperature without any preliminary thermal treatment of Ce. The hydride CeH/sub 3/ is obtained at room temperature (14 to 21 deg ) regardless of the hydrogen pressure. The diagram showing the dependence of hydride content on the temperature and the diagram of the rate of hydridation confirm the formation of CeH/sub 2/ and CeH/sub 3/ and the appearance of the interchanging phase between CeH/sub 2/ and CeH/sub 3/.
