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.
Ternary chromites of the composition LaM I Mg(CrO 3 ) 2 (M I = Li, Na, K) were synthesized for the first time by ceramic technology from stoichiometric amounts of high purity grade La 2 O 3 ; pure for analysis grade Li 2 CO 3 , Na 2 CO 3 , K 2 CO 3 , and MgCO 3 ; and chemically pure grade Cr 2 O 3 . Using X-ray diffractometry, it has been established that compounds are crystallized in cubic and tetragonal crystal systems, and parameters of their crystal lattices have been determined.
