dc.description.abstractHydroxyapatite (HA) which compose around 70 % of our bone is an example of bioactive ceramics most commonly used in bone implantation. Because of their excellent bioactivities, hydroxyapatites are regarded as attractive biomedical materials. In this work we have succeeded in producing hydroxyapatite powder by using eggshell waste as the raw material. Eggshell waste is available in huge quantity from food processing, egg breaking and hatching industries. The process involved drying and thermal decomposition of eggshell into calcium oxide followed by hydrothermal reaction at low temperature with diammonium hydrogen phosphate and water. The produced hydroxyapatite powder is extraordinarily fine with nanosize primary particles. Its high purity proved that the product fulfills medical requirement. The present invention provides an environmentally beneficial and cost effective method of producing medical grade hydroxyapatite materials utilizing eggshell waste. � 2008 Springer-Verlag.en_US
