1.1 Glass Chemistry and Spherical Style

(Hollow glass microspheres)

Hollow glass microspheres (HGMs) are microscopic, spherical fragments made up of alkali borosilicate or soda-lime glass, typically varying from 10 to 300 micrometers in size, with wall surface densities between 0.5 and 2 micrometers.

Their defining feature is a closed-cell, hollow interior that presents ultra-low thickness– frequently listed below 0.2 g/cm two for uncrushed balls– while keeping a smooth, defect-free surface area important for flowability and composite integration.

The glass structure is engineered to balance mechanical strength, thermal resistance, and chemical resilience; borosilicate-based microspheres use premium thermal shock resistance and lower alkali web content, reducing reactivity in cementitious or polymer matrices.

The hollow framework is created with a regulated growth process during production, where precursor glass fragments including a volatile blowing representative (such as carbonate or sulfate compounds) are warmed in a heating system.
