The advantage of hollow glass microspheres is that their ability to be customized with respect to diameter, density (very small microspheres below 1 micron in diameter can be designed to remain in suspension indefinitely), surface charge density, type of surface group, color and fluorescent response, among other properties. Hollow glass microspheres can be monodisperse with very tight particle-size distribution.
Depending on the raw materials used, each type of hollow glass microsphere offers unique advantages suitable for particular applications. Due to their small, spherical structure, all types of hollow glass microspheres share some advantages. The sphere is nature’s most efficient shape, with the least surface area compared to volume. It is this shape that gives hollow glass microspheres such unique properties.
