Hollow Glass Microspheres: Lightweight Inorganic Fillers for Advanced Material Systems glass microbubbles
1. Product Make-up and Structural Layout 1.1 Glass Chemistry and Spherical Design (Hollow glass microspheres) Hollow glass microspheres (HGMs) are microscopic, spherical particles composed of alkali borosilicate or soda-lime glass, normally varying from 10 to 300 micrometers in diameter, with wall surface densities between 0.5 and 2 micrometers. Their specifying attribute is a closed-cell, hollow…
