摘要：
Silica particles having a BET surface area from 0.1 to 7m2/g, a pack density from 35 to 55 lb/ft3, an Einlehner abrasion value from 8 to 25 mg lost/100,000 revolutions, a total mercury intrusion pore volume from 0.7 to 1.2cc/g,and a stannous compatibility from 70 to 99 pcnt , are disclosed, as well as methods for making these silica particles.
