Abstract
In a system and method for producing submicron sized particles from a substance, the system may comprise a constant current power supply, a furnace for vaporizing the substance having a chamber for containing the substance, and a condensation unit for rapid cooling of the vaporized substance. The furnace may comprise an insulating outer section, a chamber wall, and two electrodes.
Claims18
A system for producing submicron sized particles from a substance, the system comprising:
- a constant current power supply configured to produce a current of constant magnitude over a range of voltage and having a short circuit current, and for which the short circuit current is limited to avoid damage to the constant current power supply,
- a furnace having a chamber for containing the substance, the furnace comprising an insulating outer section, a chamber wall electrically and thermally conductive for resistively heating the chamber in a presence of an electric current flowing through the chamber wall, and two electrodes electrically coupled to the constant current power supply and mechanically, electrically, and thermally connected to the chamber wall,
- a condensation unit having an interior for rapid cooling and collecting submicron sized particles of the substance, and
- and a venting tube connecting the chamber of the furnace to the interior of the condensation unit for directing vaporized substance to the interior of the condensation unit,
- wherein the chamber wall has an open-ended annular shape, and the two electrodes are endcaps of the open-ended annular shape such that electricity from the constant current power supply flows from the two electrodes to the chamber wall, and
- wherein each of the chamber wall and the two electrodes are comprised of graphite, and the constant current power supply is configured to provide power to achieve an operating temperature inside the furnace chamber above a boiling temperature of the substance for a duration to vaporize all the substance inside the furnace chamber.

A method for producing submicron sized particles from a substance, the method comprising:
- placing the substance having a boiling temperature inside a chamber of a furnace, the furnace comprising an insulating outer section, a chamber wall electrically and thermally conductive for resistively heating the chamber in a presence of an electric current flowing through a material of the chamber wall, and two electrodes mechanically, electrically, and thermally connected to the chamber wall,
- supplying the electric current from a constant current power supply electrically coupled to the two electrodes at a power level to raise an operating temperature inside the furnace chamber above the boiling temperature of the substance inside the furnace chamber and for a duration long enough to vaporize all of the substance, the constant current power supply configured to produce a current of constant magnitude over a range of voltage and having a short circuit current, and for which the short circuit current is limited to avoid damage to the constant current power supply,
- and collecting submicron sized particles of the substance inside a condensation unit, wherein the condensation unit having an interior for rapid cooling of the substance,
- wherein the chamber wall has an open-ended annular shape, and the two electrodes are endcaps of the open-ended annular shape such that electricity from the constant current power supply flows from the two electrodes to the chamber wall, and
- wherein each of the chamber wall and the two electrodes are comprised of graphite, and the interior of the condensation unit is connected to the furnace chamber by a venting tube.
