Abstract
Metal-carbon composite powders and methods for producing metal-carbon composite powders. The powders have a well-controlled microstructure and morphology and preferably have a small average particle size. The method includes forming the particles from an aerosol of powder precursors. The invention also includes novel devices and products formed from the composite powders.
Claims33
A powder batch of metal-carbon composite particles, said each composite particle comprising at least about 3 weight percent carbon and a metal phase, wherein said composite particles are substantially spherical and have a weight average particle size of from about 0.1 .mu.m to about 20 .mu.m.
A powder batch of metal-carbon composite particles, said each composite particle comprising a metal phase and a carbon phase, and wherein said composite particles are substantially spherical and comprise at least about 70 weight percent carbon and wherein said composite particles have a weight average particle size of from about 0.1 .mu.m to about 20 .mu.m.
A powder batch of metal-carbon composite particles, said each composite particle comprising a metal phase and a carbon phase, and wherein said particles comprise at least about 70 weight percent of said metal phase and at least about 3 weight percent carbon and wherein said particles have a weight average particle size of from about 0.1 .mu.m to about 10 .mu.m.
