Methods are disclosed for dispersing a powder mixture of at least one metal carbide powder and at least one cobalt powder in at least one apolar medium with at least one dispersant and, optionally, at least one wetting agent. According to the invention, the dispersant is an effective dispersant for both cobalt and metal carbide surfaces. The invention is particularly useful for powder mixtures with a fine grained cobalt powder and a relatively high cobalt content. The dispersant used is an amphiphilic compound with a branched copolymer structure.
