The influence of content of cryptocrystalline graphite of Kureysk Field, activated in a planetary centrifugal mill AGO-2, on the technological properties of mold coatings used for low-pressure die casting and castability of AK12 alloy are researched. It was found that the optimum properties of coating are achieved by the introduction into their composition 15 wt. % of activated graphite. Also it was found that with increasing content of graphite, the castability of AK12 alloy and roughness of castings are decreases. The comparative laboratory and pilot testing of coatings based on natural, enriched and activated graphite showed that coatings based on activated graphite can be recommended for molds.
