Wong, Lydia Helena, Tio, Betty, & Miao, Xigeng (2002) Functionally graded tricalcium phosphate/fluoroapatite composites. Materials Science and Engineering C: Biomimetic Materials, Sensors and Systems, 20(1-2), pp. 111-115.
This study was conducted to prepare fluorine-substituted apatite (FA)/beta-tricalcium phosphate (h-TCP) composites to combine the biostability of FA with the bioresorbability of h-TCP. The FAwas prepared for the first time by mixing hydroxyapatite (HA) with aluminium fluoride (coded as AF). On the other hand, the h-TCP was prepared from a mixture of HA and CaHPO4 (calcium hydrogen phosphate). The dissolution behaviour of the composites was tested using a 10-wt.% citric acid solution. Scanning electron microscopy (SEM) indicated that h-TCP dissolved in the citric acid much faster than FA, resulting in macropores among the FA matrix. In addition to bulk FA/h-TCP composites, novel functionally gradient FA/h-TCP composites were also prepared by varying the particle size and the volume content of the h-TCP granules. The functionally gradient FA/h-TCP composites could be used to design implants.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
