One. Scientific Foundations of Hollow Glass Microspheres 1.one Composition and Microstructure 1.1.one Chemical Composition: Borosilicate Dominance Hollow glass microspheres (HGMs) are generally composed of borosilicate glass, a cloth renowned for its minimal thermal enlargement coefficient and chemical inertness. The chemical makeup ordinarily involves silica (SiO₂, fifty-90%), alumin... https://padlet.com/okok0972149980/okok093-p57jo614mu84dt15/wish/0BA3ZpGApr7zQnPb
