1. Scientific Foundations Of Hollow Glass Microspheres one.one Composition and Microstructure one.1.one Chemical Composition: Borosilicate Dominance Hollow glass microspheres (HGMs) are mostly composed of borosilicate glass, a fabric renowned for its lower thermal expansion coefficient and chemical inertness. The chemical make-up usually includes silica (SiO₂, 50-ninety%), alumina (Al... https://padlet.com/okok0972149980/okok093-p57jo614mu84dt15/wish/yEPVZknVzz02Qb0Y
