“…They con cluded that pure' fluorapatite was not capable of existence in aqueous solutions but rather, a hydroxy-fluorapatite with a maximum content of 70$ fluorapatite. Rathje (1957a) succeeded in preparing mixtures of hydroxyapatite and fluorapatite with higher percentages of the latter than he was able to obtain in previous investiga tions. To do this, he maintained the lowest possible con centration of hydroxyl ions during the titration.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
