摘要:

用溶液量热法测定了BaCe_(0.7)Ho_(0.2)In_(0.1)O_(2.85)和BaCe_(0.7)Sm_(0.2)In_(0.1)O_(2.85)在1M盐酸中的溶解度。所获得的数据进行了比较,与早期测量的数据上的BaCe 0.7Nd 0.2In 0.1O 2.85,BaCe 0.7Gd 0.2In 0.1O 2.85的溶解度。建立了稀土元素半径与溶解速率的关系。如图所示,这种关系不是线性的。

英文摘要:

The dissolution enthalpies of BaCe0.7Ho0.2In0.1O2.85 and BaCe0.7Sm0.2In0.1O2.85 were measured by method of solution calorimetry in 1M hydrochloric acid with adding 0.1 M KI. The obtained data were compared with earlier measured data on dissolution enthalpies of BaCe0.7Nd0.2In0.1O2.85, BaCe0.7Gd0.2In0.1O2.85. The dependence of dissolution enthalpies from lanthanide radius was constructed. As was shown the relationship is not linear.
