KBaR(BO3)(2) Orthoborates (R = REE): Synthesis and Study

摘要

The search for compounds with the formula composition KBaR(BO3)(2) has been performed by solid-phase synthesis and differential thermal analysis. The compounds synthesized in this series are KBaPr(BO3)(2) and KBaNd(BO3)(2), which are isostructural to KBaY(BO3)(2), are isotypical to butschliite K2Ca(CO3)(2), and crystallize in a trigonal system with space group R (3) over barm. The structural characteristics of compounds calculated for the entire series of REEs are given.
