Calcium Phosphate Invert Glasses

Abstract

Phosphate invert glasses are composed of short phosphate groups and contain a large proportion of cations. Introducing intermediate oxides, such as TiO2, Nb2O5, ZnO, and MgO, to phosphate invert glasses can manipulate their properties via tailored manipulation of their glass network structures. TiO2, Nb2O5, and ZnO improve the chemical durability of phosphate invert glasses (i.e., reduce their ion-releasing ability), whereas MgO decreases their chemical durability (i.e., enhances their ion-releasing ability). Phosphate invert glasses can be tailored for various biomedical applications by manipulating their glass network structures to control their properties.
