Systems, methods, and devices are disclosed for producing quantum particles (e.g., quantum dots) having a uniform size by vaporization of molten precursor droplets. More particularly, the present technology produces quantum dots by melting or liquefying solid and substantially pure precursor materials followed by production of uniformly sized droplets of molten precursor by use of a droplet maker into a microwave generated plasma torch.

Described herein is a composition for antimicrobial moisture avoidance powders and substances. Copper and copper alloys have been known to possess antimicrobial activity. Calcium carbonate and magnesium carbonate that is infused with chalk are effective at not only drying the skin and avoiding moisture, but also possess strong antimicrobial activity. According to one embodi-ment, a composition for a moisture avoidance powder comprises copper oxide with one or more of calcium carbonate and magnesium carbonate. The copper oxide may be included in the composition at a minimum ratio of 1 part copper oxide to 1000 parts of the combination mixture of one or more of calcium carbonate and magnesium carbonate. That composition can be combined with alcohol to produce a moisture avoidance substance in a liquid or cream form with antimicrobial properties.

It has been unexpected found that the machinability and corrosion resistance of powder metal parts can be greatly improved by incorporating calcium aluminoferrite powder, such as naturally occurring brownmillerite powder (Ca.sub.2(Al,Fe).sub.2O.sub.5), into the part. Improved machinability is of enormous value in manufacturing countless parts where it is necessary or desirable to machine the part after it has been sintered, such as is frequently the case with gears, rotors and sprockets. In the practice of this invention, calcium aluminoferrite powder can also be incorporated into parts which will not necessarily be machined for the sole purpose of attaining better corrosion resistance. Surprisingly, the incorporation of the calcium aluminoferrite powder into such parts does not significantly compromise the strength, durability, or wear characteristics of the part and generally improves the service life of the part by providing better corrosion resistance.

A method for producing a metal powder includes maintaining molten reducing metal in a sealed reaction vessel that is free of added oxygen and water, establishing a vortex in the molten reducing metal, introducing a metal halide into the vortex so that the molten reducing metal is in a stoichiometric excess to the metal halide, thereby producing metal particles and salt, removing unreacted reducing metal, removing the salt, and recovering the metal powder. The molten reducing metal can be a Group I metal, a Group II metal, or aluminum.

The invention involves producing discontinuous, flake-shaped particles of a soft magnetic material, coating the flake-shaped particles with an electrically insulating coating, and consolidating the coated flaked-shaped particles to form a soft magnetic bulk shape. The consolidated bulk shape can comprise a layer or a simple or complex 3D magnet part shape, which has a consolidated layered microstructure that includes laminated soft magnetic regions that are substantially encapsulated by an electrical insulating layer to increase the resistivity of soft magnetic material, especially when used in silicon iron magnet parts.
