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.
Some fluorophosphates are used as a dental materials. The most traditional and popular monofluoromonophosphate is Na2PO3F. Some other fluorophosphates may be interesting for similar purposes, for example, fluoropolyphosphates. We studied the formation of fluorophosphates via reaction of sodium cyclotriphosphate and sodium fluoride at boiling in water solution.
