  • The effect of binder on chemically precipitated hydroxyapatite during spray drying = Vpliv veziva na kemijsko izločeni hidroksiapatit med atomizacijo
    Baştan, Fatih Erdem ...
    The synthesis of appropriate calcium phosphate powders for thermal-spraying applications is a fundamental, crucial stage in the production of bioceramical coatings coupled with the desired ... characteristics. The performance, lifespan and quality of the resulting biological coating in-vivo is largely dependent on the coating morphology, phase composition, particle size and the crystallites of the spray powders. In order to achieve very reliable coatings from thermal-spray processes, spherical powders of a specified size distribution are recommended. The aim of this work was to produce hydroxyapatite powder with a chemical precipitation method and to reshape it in a spray dryer and investigate the effect of binder on the powder structure to provide an insight into the preparation and characterization aspect of HA powders using the spray-drying process. Ethanol, pure water and polyvinilalcohol (PVA) + ethanol were used as the binder. Different temperatures were applied in the spray dryer. Then, the precipitated, spray-dried powders were examined for morphology. Scanning electron microscopy (SEM), X-ray diffraction (XRD), (EDX) and ICP were used to characterize the specimen powders.
