| description | A method of forming a carbothermally reduced powder of nitrides or carbides is disclosed. The product powder consists principally of unagglomerated particles and is formed by providing a collection of precursor particles in colloidal dispersion, adding to the dispersion a polymerizable monomer, polymerizing the monomer to matrix the precursor particles in discrete, well dispersed positions and carbothermally reducing the particles followed by removing excess carbon by burning. The polymer matrix acts as an agglomerate-inhibiting carbon source during carbothermal reduction. |
