Abstract
A process for forming particles. The process includes a step of entraining gas into a precursor material, wherein the gas includes from about 50 vol % to about 100 vol % argon and from about 0 vol % to about 50 vol % other constituents. The precursor material is deposited onto a moving conveyor. The precursor material is cooled to form a plurality of particles.
