摘要：Disclosed is a process for producing ceramic particles, such as proppants, thathave 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 percentof a second ceramic material. The sintering temperature of the first ceramic material maybe lower than the sintering temperature of a second ceramic material. Heating theprecursor to a maximum temperature above the sintering temperature of the firstmaterial and below the sintering temperature of the second material. Also disclosed is aceramic article that has a particular combination of chemistry and alumina crystallinephase.
