Abstract:To increase the biocompatibility of hydroxyapatite (HA), Ca 10 (PO 4 ) 6 (OH) 2 , the Sr substitution of Ca into the HA structure was effected to yield Ca 10−x Sr x (PO 4 ) 6 (OH) 2 (Sr-HA). For medical and dental applications, it is important that Sr-HA is prepared as a thin film so that the Sr fully substitutes the Ca sites in the HA structure and does not form segregated impurities consisting of Sr compounds. If the segregated Sr forms different amounts of different impurities, the dissolution of the Sr int… Show more
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.
