One. Scientific Foundations of Hollow Glass Microspheres 1.one Composition and Microstructure 1.one.one Chemical Composition: Borosilicate Dominance Hollow glass microspheres (HGMs) are principally composed of borosilicate glass, a fabric renowned for its reduced thermal enlargement coefficient and chemical inertness. The chemical makeup commonly contains silica (SiO₂, fifty-ninety%),... https://padlet.com/okok0972149980/okok093-p57jo614mu84dt15/wish/0BA3ZpGApr7zQnPb
