"Glasses of the formula xNa2O*xCaO*(100-x)B2O3 glasses (where 5≤ x≤ 20) were reacted in pH 4, 7, and 10 buffer solutions, and distilled water at room temperature. Trends in weight loss and pH change were analyzed. Dissolution rates were calculated after two hours in solution. Inductively Coupled Plasma-Optical Emission Spectroscopy and Atomic Absorption analyses were performed on the post reaction solutions. Infrared Reflectance Spectroscopy, X-Ray Diffraction, and Analytical Scanning Electron Microscopy were used to characterize the reacted surfaces. All compositions dissolved congruently in all solutions studied. The minimum in dissolution rate for a particular solution corresponds to the composition with the greatest fraction of four coordinated borons, 30-35 mole% [Na2O+ CaO] as has been documented previously"--Abstract, page ii.
