ABSTRACT:
Precipitated silicas having wet cake moisture values in excess of 85%, BET surface areas of 600-700 m.sup.2 /g, oil absorption values of 50 to 60 cc/100 g, total intruded volume of about 1.2 to 0.8 cc/g, and a median pore radius of 50 .ANG. to 20 .ANG. are produced by a low temperature silica precipitation process. The silicas have unique flatting characteristics and are additionally useful as conditioning agents for food and salt and in dentifrice compositions.
