The article presents the results of studies on the purification of sludge obtained by converting waste tungsten carbide and cobalt hard alloys into a cobalt solution with electrolysis to the state of pure tungsten carbide powders. Conducted scientific and practical studies show that the original...

The article presents the results of research on the production of nanopowders by synthesizing tungsten carbide powders obtained from waste tungsten carbide-cobalt hard alloy in countercurrent filtration mode. The conducted scientific and practical studies show that with an increase in the amount of...
