The present invention provides silica particles, which include the following
physical properties: BET surface area: 100-700 m2/g; DBP absorption:
100-500 g/100 g; tamped density: 100-250 g/l; ALPINE sieve residue63:
5%; and particle sizes (cumulative volume distribution): d9540
m; d5020 m; and d510 m.
The present invention also provides a process for producing silica having a narrow
particle size distribution, which includes drying a silica suspension in a pulse
combustion dryer to produce silica particles having the following particle size
distribution (cumulative volume distribution): d510 m;
d5020 m; and d9540 m.
