Structural Evolution and Phase Formation During Synthesis of Phosphate-Containing Sol-Gel Derived Bioactive Calcium Silicate 58S Glasses

摘要

These studies demonstrate the first observations of HA formation during conventional sol-gel 58S synthesis using TEP as the phosphate precursor and calcium nitrate tetrahydrate as the calcium source. CME also performs as an excellent alternative to calcium salts for the incorporation of calcium into the silica network at processing temperatures below 60 ℃, and for improved homogeneity of glasses stabilised at higher temperatures.
