Abstract
Metal coated powders are produced by suspending a precursor metal salt and the powder to be coated in a glycol. This mixture is heated, and the metal salt is reduced and the metal precipitates as a coating onto the powder.
Claims12
A method for forming a metal-coated powder, comprising:
- mixing a precursor of at least one metal and the powder to be coated with a glycolic or diol solvent to form a reaction mixture;
- and refluxing said reaction mixture so that the glycolic or diol solvent reduces said precursor to the metal over time to produce powder coated with said metal.
