Abstract

Disclosed herein are synthetic microparticles substantially free of monovalent and divalent metal elements and a method of forming such synthetic microparticles. The synthetic microparticle may be suitable for use as a density modifying filler. The synthetic microsphere can be made from an agglomerate precursor that includes an aluminosilicate material, such as fly ash, a blowing agent such as sugar, carbon black, and silicon carbide, and a binding agent. The synthetic microsphere is produced when the precursor is fired at a pre-determined temperature profile so as to form either solid or hollow synthetic microspheres depending on the processing conditions and/or components used. The synthetic microparticle is capable of being formed into a large range of predetermined shapes.
