The invention relates to a method for manufacturing sintered refractory grains containing Cr2CO3 from an initial refractory product including one or more chromium oxides, all the dimensions of the starting refractory material being no lower than 1 mm, said method including the following steps, in the following order: A) optionally, a step of crushing the starting refractory material; B) grinding a filler to be ground, comprising said starting refractory material that was optionally crushed, in a liquid medium in order to obtain a suspension of particles of said starting refractory material, more than 80% of said particles, by weight percentage, having a size of less than 50 [mu]m; C) preparing a starting mixture including at least 1 wt% of particles of the suspension obtained during the preceding step; D) shaping the starting mixture into the shape of a preform; E) optionally drying the preform obtained in step D); F) sintering the preform so as to obtain a sintered body; G) optionally grinding the sintered body; H) the optional selection by particle size, steps D), G) and H) being adapted such that the sintered body, optionally crushed and/or selected, is in the form of a grain or a granular powder.
