Properties of Sm₂O₃—Al₂O₃--SiO₂ Glasses for in Vivo Applications
Abstract
The compositional range for glass formation below 1600°C in the Sm2O3─Al2O3─SiO2 system is (9-25)Sm2O3─(10-35)Al2O3─(40-75)SiO2 (mol%). Selected properties of the Sm2O3─Al2O3─SiO2 (SmAS) glasses were evaluated as a function of composition. the density, refractive index, microhardness, and thermal expansion coefficient increased as the Sm2O3 content increased from 9 to 25 mol%, the values exceeding those for fused silica. the dissolution rate in 1N HCl and in deionized water increased with increasing Sm2O3 content and with increasing temperature to 70°C. the transformation temperature (Tg) and dilatometric softening temperature (Td) of the SmAS glasses exceeded 800° and 850°C, respectively.
