title: Effects of silica sol on the microstructure and mechanical properties of CaSiO3 bioceramics.
abstract: CaSiO3 ceramics were fabricated with silica sol addition by pressureless sintering. The effects of silica sol on phase composition, microstructure and mechanical properties of CaSiO3 ceramics were investigated. The silica sol additive was found to be effective in speeding up pore elimination, improving the grain growth, decreasing the sintering temperature and shortening the sintering time. When the amount of SiO2 was 5wt%, a flexural strength of 186.2MPa was achieved with an open porosity of 3.9%. The main crystal phase was β-CaSiO3 below sintering temperature of 1150°C.
