COMPLEX OF CERAMIC PARTICLES AND METHOD OF ITS PRODUCTION (VERSIONS) Russian patent published in 2014 - IPC C04B35/01 C04B35/10 C09K8/80 

FIELD: chemistry.

SUBSTANCE: disclosed is complex of ceramic particles, which contains multitude of separate loose particles, which can be applied in a range different industrial processes and products, including, for instance, abrasive media as granular coating of roofing shingles based on bitumen, as filtering medium for liquids, as sand substituent in processes of casting on melted models and as propants in drilling works with DTH hammer, in which ceramic particles can be named propants. This multitude has complete weight and granulometric composition of particles. Effective width of granulometric composition exceeds 100 microns and contains three adjoining and non-crossing areas, which include first area, second area and third area. First area adjoins second area, and second area adjoins third area. Width of second area constitutes, at least, 25% of effective width. Weight of particles in second area does not exceed 15% of complete weight of multitude of particles. Weight of particles in first area and third area each exceeds weight of particles in second area.

EFFECT: complex of particles, possessing certain characteristics for increasing resistance to crushing, specific conductivity and stability to sedimentation with simultaneous reduction of production costs for enterprise producing ceramic particles.
