Abstract: The invention relates to a novel process for preparing a precipitated silica, in which: a silicate is reacted with an acidifying agent, so as to obtain a suspension of precipitated silica, said suspension of precipitated silica is filtered, so as to obtain a filter cake, said filter cake is subjected to a liquefaction operation, after the liquefaction operation, a drying step is performed, characterized in that at least one polycarboxylic acid is added to the filter cake, during or after the liquefaction operation. The invention also relates to novel precipitated silicas and to uses thereof.
