ABSTRACT:
A method of making a hard constituent powder coated with Co and/or Ni in a solution by liquid reduction of the Co and/or Ni from a suitable metal compound with a polyol while keeping the powder in suspension, the polyol functioning both as a solvent and as a reducing agent at the same time. By separating the intermediate solid compound and hard constituent from the suspension before any by-products are formed and reducing the intermediate solid compound in the dry state by H.sub.2 for around 24 hours or by using an excess of about 10 times more moles polyol than moles metal, the polyol can be conserved or reused leading to improved cost efficiency of the process.
