Abstract

The effect sintering parameters and various amounts of additives on the TiO₂-HA-CaSiO₃ composites was investigated this study. TiO₂/CaSiO₃/HA composites were prepared and characterized by means of physical and mechanical properties. The addition of TiO₂ and HA to wollastonite was studied by means of bulk density and Vickers Hardness. The wollastonite composites containing TiO₂ (10-30 wt%) and HA (20-40 wt%) were sintered between 1230-1270°C, with a ramp rate of 10°C/min and a holding time of 1,1.5 and 2 hours. The results indicate that a higher sintering temperature played a significant part in enhancing the physical and mechanical properties as compared to results shown by pure wollastonite, especially for composites containing higher TiO₂ (25-30wt%) and lower HA (20-25wt%).
