Microsphere

Microspheres

Microspheres can be made from various natural and synthetic materials. Glass microspheres, polymer microspheres, metal microspheres, and ceramic microspheres are commercially available. Solid and hollow microspheres vary widely in density and, therefore, are used for different applications. Hollow microspheres are typically used as additives to lower the density of a material. Solid microspheres have numerous applications depending on what material they are constructed of and what size they are.
