Abstract: Polymer coated particulates may be produced by melt emulsification methods, for example, by mixing a mixture comprising: a carrier fluid, particulates, a thermoplastic polymer, and optionally an emulsion stabilizer at a temperature at or greater than a melting point or softening temperature of the thermoplastic polymer, wherein a mass ratio of the particulates to the thermoplastic polymer is about 1:0.1 to about 1:5; cooling the mixture to below the melting point or softening temperature to form polymer coated particulates; and separating the polymer coated particulates from the carrier fluid.

Abstract: A method for producing metal or metal alloy particles may include: mixing a mixture comprising: (a) a metal or a metal alloy, (b) a carrier fluid, and optionally (c) an emulsion stabilizer at a temperature at or greater than a melting point of the metal or the metal alloy to create a dispersion of molten droplets of the metal or the metal alloy dispersed in the carrier fluid; cooling the mixture to below the melting point of the metal or the metal alloy to form metal or metal alloy particles; and separating the metal or metal alloy particles from the carrier fluid, wherein the metal or metal alloy particles comprise the metal or the metal alloy and the emulsion stabilizer, if included.
