Bioactivity Assessment of Hydroxyapatite Coatings Produced by Alkali Conversion of Monetite

摘要

Commercially pure titanium sheets were coated with hydroxyapatite using three different routes: alkali conversion of monetite to hydroxyapatite utilising NH_4OH, KOH and NaOH solutions with pH=12.5 The hydroxyapatite coatings produced by each of the three different routes all exhibited similar morphologies and crystallinities, and hydroxyapatite was the only crystalline phase observed in all the coatings.
