Description

It was proved that there are two isomorphic series of mixed crystals in the CeO2-La2O3 systems from 0 to 14 mol% CeO2-mixed crystals based on the La2O3 structure and from 32 to 100 mol% CeO2-mixed crystals based on the CeO2 structure. The oxides were obtained by co-precipitation of oxalates, followed by heating at 850 0C. The changes of the parameters of the lattice with the changes of the composition were investigated. Also the solubility of the mixed crystals in 25% HCl was determined. (author)
