Synthesis of nano sized hydroxyapatite powder using sol-gel technique and its conversion to dense and porous bodies

Hydroxyapatite powder has been prepared via sol-gel procedure using calcium nitrate tetrahydrate and diammonium hydrogen phosphate as the precursors for calcium and phosphorus, respectively. XRD measurement shows that the powder contains hydroxyapatite crystals with ß-TCP and calcium oxide as second...
