β- TCP was synthesized by changing the process parameters and all samples were characterized in terms of density, porosity, XRD and FTIR analysis. Density rose and porosity decreased with rising of pH value and density found maximum (2.31 g/cc) at pH 10. Sharp peaks in the XRD diffractograms ensured the crystallinity of samples which increased after calcination and sintering process. Average crystal size was found 28.21 nm. IR spectrum at 943.19 cm-1 and 972.12 cm-1 appeared in FTIR analysis proved the presence of pure β- TCP exists in resulting samples. Performance to stress increased with pH and maximum compressive strength was found at pH 10. Calcination was found maximum 3.485 Nmm-2 at 900°C minimum 1.352 Nmm-2 at 800°C.
