摘要： A proppant may include a sintered ceramic, wherein the sintered ceramic has a composition including an alumina (Al2O3) content ranging from about 60% to about 78% by weight, an iron oxide (Fe2O3) content ranging from about 5% to about 20% by weight, a silica (SiO2) content ranging from about 1% to about 10% by weight, a titania (TiO2) content ranging from about 2% to about 8% by weight, and a combined iron oxide and titania content of at least about 11% by weight. A proppant may include a sintered ceramic. The sintered ceramic may have a composition including a calcium oxide (CaO) content ranging from about 1% to about 5% by weight. A rod-shaped proppant may include a sintered ceramic having an aspect ratio ranging from about 1.5 to about 3, an apparent specific gravity ranging from about 2.0 to about 4.0, and a pack porosity of greater than 49%.

摘要： Disclosed herein are granulated inorganic particulate compositions exhibiting at least one property chosen from improved material handling, low dusting, easy make-down in to mineral-water slurry, and requiring lets energy to produce than spray dried inorganic particulate products. In one embodiment, the granulated inorganic particulate compositions are characterized by a moisture content ranging from 2% to 60% by weight relative to the total weight of the composition, such as for example from 2% to 10% or from 30 to 50%. In another embodiment, the granulated inorganic particulate compositions have an average granule size of greater than about 10 mesh. In a further embodiment, the granulated inorganic particulate composition comprises granules of inorganic particulate that are friable when subjected to a shear force. The granulated inorganic particulate may take on any shape, ranging from and including but not limited to very angular, to sub-rounded, to approximately spherical (i.e., having a Krumbein sphericity of at least about 0.8).
