Influence of Mg doping on the early steps of physico-chemical reactivity of sol–gel derived bioactive glasses in biological medium
Abstract
The aim of this study is to highlight the influence of magnesium doping on the surface reactivity of binary (SiO2–CaO) and ternary (SiO2–CaO–P2O5) bioactive glasses, prepared by sol–gel chemistry, in biological conditions. These materials were produced in powder form, and their compositional and textural properties characterized. They were then soaked in biological fluids for different delays from 0 to 4 days. The surface changes were characterized using Particles Induced X-ray Emission (
