METHOD OF PREPARING CERIUM HYDRIDE

摘要

chemical industry. SUBSTANCE: anhydrous cerium chloride and lithium hydride are heated at 700-1000 C in inert atmosphere. Reaction mixture is discharged into cooled water and product is tried with alcohol. Heat treatment at 700-740 C gives cerium hydride composed of CeH2,73. Heat treatment at 720 C and then at 1000 C gives CeH2 composed of beta and gamma phases. EFFECT: more efficient preparation method. 3 cl, 2 ex
