Abstract
Nano-scale particles of materials can be produced by vaporizing material and allowing the material to flow in a non-violently turbulent manner into thermal communication with a cooling fluid, thereby forming small particles of the material that can be in the nano-scale size range. A raw material feeder can be configured to feed raw material toward a heater which vaporizes the raw material. The feeder can include a metering device for controlling the flow of raw material toward the heater. A gas source can also be used to cause gas to flow through a portion of the raw material feeder along with the raw material.
