Closed access Metadata (CSL-JSON)
DOI 10.1134/s0036023617090133
Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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