1. Scientific Foundations Of Hollow Glass Microspheres one.1 Composition and Microstructure one.one.1 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 usually includes silica (SiO₂, 50-ninety%), alumina (A... http://myworldgo.com/profile/okok0972/action_id/3410029/show_comments/1
