    Abstract: A sintered ceramic particle made from a ceramic material having a true density greater than 3.5 g/cc and a composition having no more than 30 weight percent silicon oxide and at least 15 weight percent iron oxide, based on the combined weight of the oxides of aluminum, iron and silicon, is disclosed. A proces that utilizes an externally applied compressive force to make a ceramic particle is also disclosed.

    Abstract: Disclosed is a population of ceramic particles that includes a plurality of individual, free flowing particles, The plurality has a total weight and particle size distribution. The effective width of the distribution is the difference between the distribution's d95 and d5 particle sizes. The distribution's effective width exceeds 100 5 microns and includes three abutting and non-overlapping regions that include a first region, a second region, and a third region. The first region abuts the second region and the second region abuts the third region. The width of the second region is at least 25% of the effective Width. The weight of particles in the second region does not exceed 15% of the plurality of particle's total weight. The weight of particles in the first region and io the third region each exceed the weight of particles in the second region, Methods of making the populations of ceramic particles are also disclosed

    Abstract: Disclosed is a process for producing ceramic particles, such as proppants, that have at least 10 percent total porosity. The process includes forming a particle precursor that includes 5 percent to 30 percent of a first ceramic material and at least 40 percent of a second ceramic material, The sintering temperature of the first ceramic material may be lower than the sintering temperature of a second ceramic material. Heating the precursor to a maximum temperature above the sintering temperature of the first material and below the smntering temperature of the second material. Also disclosed is a ceramic article that has a particular combination of chemistry and alumina crystalline phase. BA. J iV14 B
