1. Scientific Foundations Of Hollow Glass Microspheres 1.one Composition and Microstructure 1.1.one Chemical Composition: Borosilicate Dominance Hollow glass microspheres (HGMs) are largely made up of borosilicate glass, a fabric renowned for its low thermal growth coefficient and chemical inertness. The chemical make-up normally includes silica (SiO₂, 50-ninety%), alumina (Al₂O₃, ten... https://sites.google.com/u/0/d/1ddXgp-GnsfUqOaRS3BFWlUN3gzl_cu1v/p/17VZq1QdfhnfMrdo9ZvBkMG_t6KM0zsQF/publishview
