Abstract—Borosilicate glasses of two compositions are synthesized and investigated with the aim of preparing glass microspheres from them. Using the Appen and Okhotin additive methods, the physicochemical properties of the glasses and melts are calculated, their crystallization ability and water stability are experimentally studied, their intrinsic temperatures are determined using dilatometry and differential scanning calorimetry, and their TLCE values are obtained.

Keywords: borosilicate glass, hollow glass microsphere, viscosity, surface tension, crystallization ability, mechanical and chemical strength
