Hydroxyapatite (Ca10(PO4)6(OH)2-HAp), is an excellent inorganic biomaterial and finds various applications. As it is similar to inorganic matrix of human bone and dental enamel, pure and doped HAps are widely studied. In the present study, pure nano-HAp and Strontium doped nano-HAp (Sr-HAp) with different concentrations were synthesized by surfactant mediated approach. The doping of strontium was confirmed by EDAX. The powder XRD study was carried out and it suggested nano-crystalline nature of the sample and the extra peaks observed other than HAp were due to the presence of brushite phase for higher concentration of Sr. TEM study revealed the needle type morphology for all the samples with size ranging from 23 nm to 78 nm. The dielectric study was carried out at room temperature within the frequency range from 102 Hz to 107 Hz and the variations of dielectric constant with frequency of applied field as well as with the concentration of strontium were studied. The results are discussed.

The microstructural and electrical properties of pure and Zirconium (Zr) doped Barium titanate (BT) samples with general formula Ba(Ti1-xZrx)O3 (where x=0.0, 0.1, 0.2 and 0.3), prepared by high temperature solid state reaction at a sintering temperature of 1250° C, were investigated. Dielectric and structural properties of BT ceramics is influenced significantly by small addition of ZrO2. Scanning Electron Microscope (SEM) observations revealed enhanced microstructural uniformity and retarded grain growth with increasing Zr content. The dielectric study with frequency at room temperature in the frequency range 75 kHz to 30 MHz shows that dielectric constant decreases with increasing frequency. The resistivity of the samples shows asymptotic behavior with the variation of frequency and was found to be of the order of ~103 Ω-m. Loss factor of the grown materials decreased with increasing frequency but it became independent at higher frequency range. doi: 10.3329/jbas.v32i2.2434 Journal of Bangladesh Academy of Sciences Vol.32(2) 2008 151-159
