1. Scientific Foundations Of Hollow Glass Microspheres one.1 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 low thermal growth coefficient and chemical inertness. The chemical make-up generally consists of silica (SiO₂, fifty-ninety%), alumi... https://pastelink.net/7to4yheu
