摘要：
X-ray diffraction studies of crystals CaF2-ErF3, CaF2-YbF3, CaxSr1-xF2 were carried out at various concentrations of rare-earth elements. Phase analysis performed by the data base PDF-2. The structural characteristics of the found phases were refined using the full-profile analysis (Rietveld method). The dependence of the lattice constant on the impurity concentration is revealed.
