| abstract |
The invention relates to a novel method for preparing a precipitated silica, consisting in: reacting a silicate with an acidifying agent, such as to obtain a suspension of precipitated silica; filtering the suspension of precipitated silica, such as to obtain a filter cake; subjecting the filter cake to a disintegration operation; and, after the disintegration operation, performing a drying step, characterised in that at least one polycarboxylic acid is added to the filter cake either during or after the disintegration step. The invention also relates to novel precipitated silicas and to the uses thereof. |
