SUBSTITUTION EFFECT ON STRUCTURE AND LEACHING PROPERTIES OF PHOSPHATE GLASSES. Authors: D. MURESAN, D. ENIU, VIORICA SIMON. |
||||||
Abstract: Two phosphate glass matrices were investigated in order to estimate the effects of substitutions both for glass former and for glass modifier on glass transition temperature and leaching properties of samples. In [10K2O•90P2O5] matrix the phosphorus oxide was partially replaced by CaO up to 35 mol % while in the calcium-phosphate glass matrix [40CaO•60P2O5] the calcium oxide was progressively stubtituted by Al2O3 up to 15 mol %. The effects consist in the increase of glass transition temperature for the samples of the first system and the decrease of glass transition temperature in the second system. At the same time differences in the leaching behaviour of the two systems are observed. | |||||||
