One. Scientific Foundations of Hollow Glass Microspheres one.1 Composition and Microstructure one.one.1 Chemical Composition: Borosilicate Dominance Hollow glass microspheres (HGMs) are primarily composed of borosilicate glass, a cloth renowned for its minimal thermal enlargement coefficient and chemical inertness. The chemical makeup ordinarily incorporates silica (SiO₂, 50-90%), alu... https://demo.jcow.net/images/viewstory/88297
