Abstract: Partially hydrophobic precipitated silica with a methanol crosslinking potential of 10-49% is new. When anhydrous, the silica has a DBP absorption > 250 g/100 g. The average particle size is 1-12 mu m and the silica has a carbon content of 0.3-1.85 %, and when dried, it loses 2.6-10 % of its weight. It has a pH of 5.5-10. The silica is prepared by mixing a silica suspension (which has been prepared using known methods) with a material that gives the silica hydrophobic properties. The mixing takes place for a very short time at conditions of low pH and high shear. The resulting suspension is filtered and washed in salt-free conditions, and the filter cake is dried, thermally treated and powdered.

Abstract: Pyrogenic silica doped with alumina by means of aerosol is based on pyrogenic silica produced by flame oxidation or flame hydrolysis and contains 1 x 10 to 20 wt.% dopant. Pyrogenic silica doped with alumina by means of aerosol is based on pyrogenic silica produced by flame oxidation or flame hydrolysis and contains 1 x 10 to 20 wt.% dopant. The amount of dopant (preferably) is in the 1-10,000 ppm range and the dopant is aluminum (Al) salt(s), a suspension of an Al compound and/or Al. The doped oxide has a BET surface area of 5-600 m /g. Independent claims are also included for (a) the production of the doped pyrogenic silica; (b) mixtures of 0.01-100% of this product and other pyrogenic or precipitated silica, bentonite and/or other fillers normally used in the paper industry.
