The invention relates to a granulated powder intended, in particular, for the production of ceramic sintered parts, said powder having the following chemical weight composition, based on dry matter, namely: at least 1 % of a first binder having a glass transition temperature less than or equal to 25 DEG C; 0 - 4 % of an additional binder having a glass transition temperature greater than 25 DEG C; 0 - 4 % of a temporary additive different from the first binder and the additional binder, the total content of the first binder, the additional binder and the temporary additive being less than 9 %; 0 - 15 % of an additive for sintering the ceramic material; at least 2 % impurities; and the remainder comprising a ceramic material, and optionally an agent for stabilising said ceramic material, to make up 100 %. According to the invention, the median diameter D50 of the powder is between 80 and 130 [mu]m, the percentile D99.5 is less than 500 [mu]m and the relative density of the granules is between 30 % and 60 %.
