Abstract

Hydroxyapatite (HAp) crystals were synthesized from gypsum powder with diammonium hydrogen phosphate solution via microwave-hydrothermal treatment at 100°C, and their properties were studied. Gypsum powder could be completely converted to fine HAp crystals 30-300 nm long with 0.5M diammonium hydrogen phosphate at 100°C in 5 min. Compared to the formation of HAp crystals via conventional-hydrothermal treatment, microwave-hydrothermal treatment led to increased rate of formation (by two orders of magnitude).
