    摘要: A method for preparing precipitated silicas is described. A precipitation reaction between a silicate and an acidifying agent is also described, wherein a precipitated silica suspension is produced, and, subsequently, separation and drying of the suspension is conducted, in which, inter alia, one of the following three operations (a, b or c) is performed: (a) simultaneously adding a compound of aluminium and a basic agent, (b) simultaneously adding a silicate and a compound of aluminium, (c) simultaneously adding the acidifying agent, a silicate and a compound of aluminium.
