Abstract
A bioactive calcium sulfate/glass composite was prepared using a sintering technique, and Ca–P–Si glass particles were
prepared by spray pyrolysis. The glass exhibited bioactivity in terms of its ability to form apatite in a simulated body fluid.
The glass was transformed into two crystallized phases, i.e., calcium phosphate and calcium silicate, respectively, during
the heating stage. The presence of the crystallized phases retarded the densification of calcium sulfate. A high sintering
temperature of 1200 °C was needed to prepare the composite. The increased addition of glass enhanced the strength and
decreases the degradation rate of calcium sulfate. The new composite is not only degradable but also bioactive.
