1.1 Glass Chemistry and Round Style

(Hollow glass microspheres)

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

Their defining attribute is a closed-cell, hollow inside that presents ultra-low density– frequently below 0.2 g/cm six for uncrushed spheres– while maintaining a smooth, defect-free surface area important for flowability and composite combination.

The glass structure is crafted to balance mechanical toughness, thermal resistance, and chemical resilience; borosilicate-based microspheres use premium thermal shock resistance and lower antacids material, lessening reactivity in cementitious or polymer matrices.

The hollow framework is created via a regulated growth process during manufacturing, where precursor glass particles having an unpredictable blowing representative (such as carbonate or sulfate compounds) are warmed in a heating system.
