Investigation of Sintering Behavior of Sol Gel Derived SiO2-Al2O3-B2O3 Glasses

Synthesizing of alumino-borosilicate glasses in the SiO2-B2O3-Al2O3 system using the sol–gel method was considered. Transparent and dense glasses were obtained by various heat treatment programs applied on the dried gels. The process of converting the gel to glass involves complex transformations including both structural and chemical changes. Consequently, investigating the sintering behavior of these synthesized powder holds significant academic merit. In order to achieve this objective, the density of monolithic glass was assessed subsequent to sintering at various temperatures. Besides, the sintering activation energy of glasses in both isothermal and non-isothermal circumstances was estimated. The relative density values for various sintered glass compositions were between 96.5- 99.6
