Abstract:
A submicron particle forming method comprising:feeding a first set of precursors to a first energy application zone; first applying energy to the first set of precursors in the first energy application zone effective to react and form solid particles having maximum diameter of no greater than 100 nanometers from the first set of precursors; ceasing application of any effective energy to the solid particles and feeding the solid particles and a second set of precursors to a second energy application zone; and second applying energy 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 with the solid particles with solid material thereabout having maximum diameter of no greater than 100 nanometers, the first and second energy application zones being the same.
