1. Scientific Foundations Of Hollow Glass Microspheres 1.one Composition and Microstructure 1.1.one Chemical Composition: Borosilicate Dominance Hollow glass microspheres (HGMs) are generally made up of borosilicate glass, a material renowned for its reduced thermal enlargement coefficient and chemical inertness. The chemical make-up normally involves silica (SiO₂, 50-ninety%), alumin... https://www.scoop.it/topic/okok0972/p/4168402012/2025/10/14/how-is-calcium-stearate-powder-s-molecular-framework-engineered
