Abstract

<abstract abstract-type="author" id="abs0005"> <title id="sect0005">Abstract</title> <sec> <p id="spar0005">Wollastonite/apatite glass-ceramics have been successfully prepared by a novel approach, consisting of the heat treatment of a silicone resin embedding micro-sized CaCO₃ particles, that act as reactive fillers, and bioactive glass powder in the SiO₂–CaO–P₂O₅–K₂O–Na₂O–MgO–CaF₂ system. Zn-containing silicates, such as hardystonite (Ca₂ZnSi₂O₇) and willemite (Zn₂SiO₄), were also developed either by directly mixing ZnO powders with the glass, or by embedding them in the preceramic polymer, as additional fillers.</p> </sec> </abstract>
