Abstract

Nano hydroxyapatite (HAp) more closely mimics the size of HAp crystals in natural bone and teeth. Due to high surface energy, nano-sized HAp powder can result in better sinterability and, therefore improve mechanical properties. In this present work, nano particle hydroxyapatite was prepared using two methods, wet chemical method and ammoniacal method. The as prepared powder and calcined powder was characterized by XRD, FTIR to study the phases of the powders. 50 vol slurry was prepared using powders calcined at 1000°C for 2 hours and sodium polyacrylate was used as deflocculating agent. After slip casting in Plaster of Paris mould, the green samples were sintered at different temperature 1100, 1200, 1250 and 1300°C for 2 hours to study the sintering behavior. Physical, mechanical and biological characterization was done for the sintered samples. © 2010 IEEE.
