Resumo: Being a major constituent of hard tissues found in humans, synthetic hydroxyapatite (HA) as a substitute to natural bone and teeth is gaining importance. In particular, nano hydroxyapatite is expected to impart considerably superior properties. The current research focuses on identification of mechanism of the formation of HA nano-crystals during its preparation when surfactant nano reactors are used for their nucleation and growth. In addition to having a rod-shaped morphology, high resolution electron microscopy has revealed the presence of 2-5 nm crystals within individual particles of HA. The HA particles were not completely hollow, rather nano sized spherical pores of about 5 nm size, have been observed in TEM. These pores are suggested to have formed due to evolution of gases during processing.
