DOI 10.1109/efre47760.2020.9242182
Data confidence 70 medium
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

This article researched the phase transitions and conductive properties of solid solutions Na3Sc2(1-x)M2x(PO4)3, where M = Cr, Yb in the concentration range x = 0 - 0.03. The peculiarities of ionic conductivity in the α- and β-, γ- phases of the studied solid solutions were clarified. The concentration dependences of the phase transition temperatures Tα→β and Tβ→γ of solid solutions of substitution Na3Sc2(1-x)M2x(PO4)3, where M = Sc, Cr have been established.
