Abstract Resorbable glasses with nominal molar compositions of 20Na 2 O·30[(1− x )CaO· SrO]∙50P O 5 , where = 0, 0.25, 0.50, 0.75, and 1, were prepared characterized. With the replacement CaO by SrO, volume, refractive index, coefficient thermal expansion increased, glass transition temperature, crystallization viscosity decreased. The SrO decreased dissolution rate in 37°C water nearly an order magnitude. fibers drawn from melts O·30CaO·50P exhibited decreasing transmission laser light (632 nm) a predictable way as fiber dissolved phosphate buffer solution. This demonstrated that these could be used to produce resorbable for temporary biosensing or therapeutic applications.
