PROCESS FOR MAKING A CERAMIC ARTICLE |
| 摘要 |
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 sintering temperature of the second material. Also disclosed is a ceramic article that has a particular combination of chemistry and alumina crystalline phase. |

1. A process, for producing a ceramic particle, comprising the steps of: forming a particle precursor comprising more than 5 weight percent but less than 30 weight percent of a first ceramic material and at least 40 weight percent of a second ceramic material, said ceramic materials substantially uniformly distributed within said precursor; heating said precursor to a maximum temperature above the sintering temperature of said first ceramic material and below the sintering temperature of said second ceramic material, wherein said ceramic particle has at least 10 percent total porosity. |
