Abstract

Inspired from the success of silicate-based bioactive glasses and glass-ceramics, alkali or/and alkali earth-containing silicate ceramics have attracted much attention in recent years. In the present paper, pure Na2CaSiO4 was successfully synthesized by a sol–gel method and its in vitro biological behaviors were investigated. The results showed that Na2CaSiO4 could quickly induce bone-like apatite formation in simulated body fluid through a silicon-rich layer. The degradation of Na2CaSiO4 in phosphorus buffered saline (PBS) was controlled by two processes: dissolution and back precipitation. Na2CaSiO4 even had the ability to induce apatite formation in PBS, which further confirmed its high apatite-inducing ability.
