Abstract

Melt-quenched glasses containing SiO2, CaO, Na2O and P2O5, and sol-gel

Foaming of binary sol-gel derived bioactive glasses containing SiO2 and CaO can be

increasing the potential for these glasses to be used as bioactive bone-regenerative

A range of experimental techniques have been used to investigate the atomic

namely Bioglass®, has been produced by combining high energy X-ray and neutron

reverse Monte Carlo (RMC) modelling. It has been shown that Ca clustering occurs

calcium within such glasses giving rise to its relatively rapid diffusion from the solid

Hydroxyapatite has been confirmed as the calcium phosphate phase which

structure of the materials and their bioactive properties.
