Porous hydroxyapatite monoliths from gypsum waste

Sachiko Furuta,   Hiroaki Katsuki  and  Sridhar Komarneni  

Abstract

Porous hydroxyapatite (HAp) monoliths were synthesized from gypsum mold waste with diammonium hydrogen phosphate solution by hydrothermal treatment at 50-190°C and their properties studied. Gypsum waste samples could be completely converted to HAp with 0.5 mol dm –3 (NH 4 ) 2 HPO 4 at 50°C in 15 days and 100°C in 2 days. This paper describes the effect of hydrothermal reaction conditions such as reaction temperature, time and concentration of (NH 4 ) 2 HPO 4 on the formation of new HAp monoliths and their porous properties.
