Elastic Properties of substituted 45S5 Bioactive Glasses and Glass - Ceramics

CuO, Fe2O3, MnO2 and ZnO substituted 45S5 bioactive glasses were prepared. Glass derived Bioactive Glass ceramics were obtained through controlled crystallization of bioactive glasses. The formed crystalline phases in bioactive glass ceramics were identified using X ray diffraction (XRD) analysis. Density and ultrasonic wave velocities of bioactive glasses and glass ceramics were measured and used to study elastic properties: Young’s modulus, shear modulus, bulk modulus and Poisson’s ratio, of bioactive glasses and glass ceramics. The results indicate that the addition of CuO, Fe2O3, MnO2 and ZnO contents in 45S5 bioactive glass enhances its density and elastic properties. The bioactive glass ceramics exhibits higher density and elastic properties when compared with their corresponding bioactive glasses.
