摘要：

CaSiO3 ceramics have been proposed as a medical material for artificial bone and dental root. In this work, CaSiO3 powders were synthesized by mixture of (CaO) and (SiO2). The samples were sintered at 1,150 degrees C for 2h. Moreover, amounts of B2O3 (5.0wt%) have been added. The in vitro bioactivity of both CaSiO3 and B2O3-CaSiO3 ceramics was investigated by soaking the powders in simulated body fluid (SBF) for various time periods to analyze the growth of hydroxyapatite (HA) on the surface of the powders. All the materials showed to be highly bioactive through the formation of a homogeneous HA on their surfaces. The B2O3-CaSiO3 showed strong hydration in the early stages of soaking in the SBF, when compared with pure CaSiO3, and the hydration was favorable for formation of carbonated HA. The results obtained indicate that the addition of B2O3 improved the biological properties of pure wollastonite.
