摘 要：<正> The temperature dependence of standard free energy of formation of LaNi5,CeNi5 has been de-termined by galvanic—cell technique using 0.95LaF3·0.05CaF2 polycrystalline solid electrolyte.The cellused can be expressed as:Mo|La,LaF3|0.95LaF3·0.05CaF2|LaNi5,Ni,LaF3|Mo（903～1173K）Mo|La|0.95LaF3·0.05CaF2|LaNi5,Ni|Mo（903～1173K）Mo|Ce,CeF3|0.95LaF3·0.05CaF2|CeNi5,Ni,CeF3|Mo（873～1023K）The experimental results are as follows:△Gf,LaNi50=-152590+13.143T±150 J/mol（903～1173K）△Gf,CeNi50=-157600+25.514T±150 J/mol（873～1023K）
