摘要：

In the present work, nanocrystalline hydroxyapatite/alumina composite was prepared under specially designed stir-type hydrothermal reactor. The composite was prepared at two different temperatures under autogenous pressure and analysed for crystallinity, size, shape, composition and thermomechanical stability. The electron microscopy study shows the formation of composite nanorods with uniform distribution. The thermogravimetry analysis reveals better thermomechanical property with minimal weight loss at increased temperature. The effect of different concentrations of composite powders against MG63 human osteosarcoma cell lines shows excellent compatibility (80%) at high concentration of . These studies facilitate the formation of biocompatible composite nanorods for biomedical applications.
