1. Scientific Foundations of Hollow Glass Microspheres 1.one Composition and Microstructure 1.one.one Chemical Composition: Borosilicate Dominance Hollow glass microspheres (HGMs) are generally composed of borosilicate glass, a cloth renowned for its lower thermal enlargement coefficient and chemical inertness. The chemical makeup typically features silica (SiO₂, 50-90%), alumina (Al₂... https://demo.jcow.net/images/viewstory/88299
