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

Abstract The solubility diagram of the ternary system NdCl3–PrCl3–H2O has been studied by the method of isothermal saturation in ampules at 25°C. In the system NdCl3–PrCl3–H2O, isovalent substitution solid solutions with the miscibility gap (PrCl3)x(NdCl3)1 – x·6H2O and (PrCl3)x(NdCl3)1 – x·7H2O have been crystallized. In the system, there is one non-invariant eutonic type point, corresponding to the saturation of the solution by two solid phases.
