Microwave- versus Conventional-Hydrothermal Synthesis of Hydroxyapatite Crystals from Gypsum

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 hydroge...

Zusammenfassung: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).
