The effects of Ca/P molar ratio on structural, morphological, dielectric and antimicrobial properties were investigated in detail using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy and dielectric measurements. The Ca/P molar ratio significantly affects the crystal structure and phase composition. The crystallite size, lattice parameters and volume of the unit cell were remarkably affected by the change in the Ca/P molar ratio. The microstructure is changed with increasing the Ca/P molar ratio. The relative permittivity and alternating current conductivity gradually decrease for the samples having the Ca/P ratios higher than 2. The dielectric loss decreases gradually with the increase of the molar ratio of Ca/P.</span></span></p><p>DOI: <a href="http://dx.doi.org/10.5755/j01.ms.22.1.7222">http://dx.doi.org/10.5755/j01.ms.22.1.7222</a></p> |
