摘　　要：以氧化铝质量分数67%的孝义铝土矿为原料制备支撑剂。通过选用两种不同粒度的铝土矿,经成球、干燥、煅烧工艺制得支撑剂成品,并讨论了粒度与升温速率对支撑剂性能的影响。本实验测试了体积密度、视密度、破碎率等支撑剂关键物理性能,并且采用XRD、SEM等手段分析了支撑剂物相组成及断面形貌。研究结果表明,原料颗粒越小、粒度范围越窄,支撑剂破碎率越低;升温速率提高致使样品视密度显著下降、破碎率显著增加。Proppant was prepared by bailing, drying and sintering process with Xiaoyi baux- ite. Physical properties such as bulk density, apparent density and breakage ratio of the proppant were tested, and the mineralogy and microstructure of the proppant were characterized by XRD and SEM. The effects of size and heating small size and narrow size distribution thus the corresponding samples exhibited rate were discussed accordingly. The results show that the starting material favored the sintering process and low breakage ratio.
