Particulate material, composites containing said material, and a method of making said particulate material. The material is composed of at least about 85% (number basis) of regular, well defined ellipsoidal particles and has a particle size less than about 25 microns, about 90% and 50% by weight of the particles being less than about 15 and about 10 microns respectively in size and has a specific surface in the range of about 0.75 to about 2.5 m2/gram as well as a specific gravity of about 2 to about 3. The composites contain said particulate material a...
Particulate material, useful as a filler for polymeric media, composed of particles: at least about 85% of which (number basis) have a well-defined, regular, ellipsoidal shape; having a particle size less than about 25m, with at least about 90% by weight of the particles having a size less than about 15m, and at least about 50% being less than about 10m, the specific surface of the particles being in the range of about 0.75 to about 2.5 square meters per gram; said particles having a specific gravity of about two to three, and being composed substantiall...
