(57) Abstract :
A metal matrix having ceramic particles distributed therein is made by the process of introducing a halide vapor of the metal forming
the matrix into flowing alkali or alkaline earth metal or mixtures thereof. A vapor of the constituents of the ceramic. Sufficient excess
alkali and/or alkaline earth metal is present to maintain the temperature of substantially all of the reaction products below the sintering
temperatures to produce metal matrix particles and ceramic particles and salt particles in excess alkali and/or alkaline earth metal. The
excess alkali and/or alkaline earth metal and the salt particles are removed leaving a niixture of metal matrix particles and ceramic
particles. A method is also disclosed.
