Abstract:
In this paper, we have reported a novel method to synthesize nanoporous hydroxyapatite (HAP) powders by freezing organic-inorganic soft solutions. The formation of porous and crystalline HAP nanopowder was achieved via calcining the samples at 600 degrees C followed by sintering at temperatures ranging from 900 degrees C to 1100 degrees C. The samples were analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopic (SEM) techniques. The results showed the formation of a carbon free nanoporous hydroxyapatite powders due to the decomposition of organic template enclosing the precipitated HAP. It was also observed that the rapid grain growth with retainment of pores while the crystallinity of the HAP nanopowder increased with the increase in sintering temperature which is substantiated from the XRD and SEM results. Such organized porous materials can act as a better biomaterial for bone tissue engineering.
