THE METHOD OF PRODUCING COMPOSITE METAL COATED METAL COMPOUND PARTICLES WHICH COMORISES THE STEPS OF DISPERSING SOLID PARTICLES OF A METAL COMPOUND SELECTED FROM THE GROUP CONSISTING OF METAL CARBIDES, METAL BORIDES, METAL SILICIDES AND METAL NITRIDES IN AN AMMONIATED SOLUTION IN WHICH SAID PARTICLES ARE INSOUBLE AND WHICH CONTAINS, IN SOLUTION, A SOLUBLE COMPOUND OF A METAL SELECTED FROM THE GROUP CONSISTING OF OSMIMUM, RHRODIUM, RUTHENIUM, IRIDIUM, GOLD, PLATINUM, PALLADIUM, SILVER, ARESENIC, COPPER, TIN PICKEL AND COBALT, REACTING THE SOLUTION WITH A REDUCING GAS AT A TEMPERATURE ABOVE ABOUT 200*F. AND UNDE A POSITIVE PARTIAL PRESSURE OF REDUCING GAS TO PRECIPITATE FROM SAID SOLUTION PARTICLES OF METAL IN ELEMENTAL FORM ON SAID METAL COMPOUND PARTICLES, AND CONTINUING THE REACTION TO COAT SAID METAL COMPOUND PARTICLES WITH SAID PRECIPITATED METAL, SAID METAL COMPOUND PARTICLES BEING PESENT IN SAID SOLUTION IN AMOUNT SUFFICIENT TO FORM WITH SAID PRECIPITATED METAL POWDER, COMPOSITE METAL COATED, METAL COMPOUND PARTICLES ADAPTED TO BE COMPACTED.
