Synthesis and characterization of hydroxyapatite/alumina ceramic nanocomposites for biomedical applications
In the present work, nanocrystalline hydroxyapatite/alumina ( HAp - Al 2 O 3 ) 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 a...

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
