Abstract

NOVEL SILICAS IN THE FONN OF POWDER AND SPHERICAL BEADS OR GRANULES. THE SILICAS ARE CHARACTERIZED BY HAVING A SPECIFIC CTAB SURFACE OF 100-140 M2/G, A SMALL MEDIAN DIAMETER, FOLLOWING DISAGGREGATION BY ULTRASOUND MEANS, AND OPTIONALLY, A POROUS DISTRIBUTION SO THAT THE POROUS VOLUME OCCUPIED BY THE PORES WHOSE DIAMETER IS 175-275 A IS LESS THAN 55OF THE POROUS VOLUME OCCUPIED BY THE PORES HAVING DIAMETERS OF 400 A OR LESS. THE INVENTION ALSO CONCERNS A METHOD FOR THE PREPARATION OF SAID SILICAS AND THEIR USE AS REINFORCING FILLERS FORELASTOMERS.
