Biyomedikal Uygulamalar için Wollastonit Partikül Takviyeli Hidroksiapatit Kompozit Granüllerin Üretilmesi ve Karakterizasyonu

Hydroxyapatite (HA) is the main inorganic component of bone and teeth having high bioactivity, biocompatibility osteointegration capability. Recently, wollastonite (WT) has been offered to reinforce HA further increase also mechanical strength. The focus this study was produce characterize HA/WT composite granules with spray drying. Commercial WT particles were introduced into lab made nanoparticles in order prepare a slurry for Spray dried (SD-HA/WT) investigated terms thermo-physical properties by SEM, FTIR, granule size analyzer, TG-DTA XRD. investigations proved that comprised both phases. contained (as matrix) entangled matrix on surface granules. heat treatment at 750 °C led calcination synthesized nanoparticles, while, sintered together 1000 1250 °C, thus integrity developed. phase structure remained stable (dominantly crystalline WT) after treatments. However, reinforcement caused decrease dehydroxylation temperature other calcium phosphates formed °C. Rietveld Refinement analysis revealed had 82.3% 15.6% phases, respectively. Spherical shaped 36 µm median (d50) would be used thermal spraying, 3d printing or hot-pressing processes.
