Abstract

Analytical explanation of an unexpected behaviour of sample densities is given. Three different types of construction of the investigated solid solutions have been recognised: normal for Z=constant versus increasing contribution of Sr substituent (X); atom-deficient for Z decreasing with X; atom-overcrowded for Z increasing with X. The mechanism of mutual transformation of the 2201-type matrix to that of the 2212-type is proposed.
