One. Scientific Foundations of Hollow Glass Microspheres one.1 Composition and Microstructure 1.one.1 Chemical Composition: Borosilicate Dominance Hollow glass microspheres (HGMs) are mostly made up of borosilicate glass, a material renowned for its small thermal expansion coefficient and chemical inertness. The chemical make-up normally includes silica (SiO₂, 50-ninety%), alumina (Al... https://nutritious-twine-caf.notion.site/Exactly-What-Is-Calcium-Stearate-Powder-28c1953aad2e80fe9935de601dfb22f2
