Abstract
This paper investigates the Microstructural and Mechanical properties of Wollastonite (CaSio3) ceramics incorporated with Titanium oxide (TiO2) and Hydroxyapatite (HA) composites preparation using Spark Plasma Sintering (SPS). And the influence of Sintering on CaSio3with additives at different temperatures ranging from 1150 °C to 1250 °C with heating rate of 100 °C/min holding time of 10 min are reported and discussed. The microstructure of the sintered samples was investigated by SEM microscopy, XRD Diffraction analyses which presented uniform distribution of the additives (TiO2/HA), having a maximum fine grain size of 32 nm. The mechanical tests were performed for hardness which was 67Hv and Compressive strength of 225Mpa were obtained at the sintering temperature 1250 °C. The superior results have been observed at the highest temperature, along with the addition of the additives (TiO2/HA) to the pure wollastonite over the physical and Mechanical properties.
