ABSTRACT:
A particle forming method includes feeding a first set of precursors to a first energy application zone. Energy is applied to the first set of precursors in the first energy application zone effective to react and form solid particles from the first set of precursors. The application of any effective energy to the solid particles is ceased, and the solid particles and a second set of precursors are fed to a second energy application zone. Energy is applied to the second set of precursors in the second energy application zone effective to react and form solid material about the solid particles from the second set of precursors. At least one precursor is fed to at least one of the first and second energy application zones as a liquid. Other aspects are contemplated.
