摘　　要：采用XRD、SEM—EDS、DTA—TG等测试方法研究Cr2O3对硫铁铝酸钡钙矿物1．75CAO·1．25BaO·2Al2O3·Fe2O3·CaSO。（C2.75，B1.25A2FS^-）的合成及性能的影响，并测试水化试样的抗压强度。结果表明，掺入适量的Cr2O3能改善硫铁铝酸钡钙矿物水化试样的抗压强度，Cr2O3，的适宜掺量质量分数为0．5％-1％。微量元素Cr的引入，可使硫铁铝酸钡钙矿物形成的温度带宽化及晶粒细化。The influence of Cr2O3 on the synthesis and performance of Ba - Beating Calcium Suffo - ferritealuminate mineral 1.75CAO ·1.25BaO · 2Al2O3 · Fe2O3 · CaSO4 （abbr; ：C2.75 B2.75A2FS^-） were studied by means of XRD, SEM - EDS and DTATG. The compressive strength were tested also. The resuits show that and proper content of Cr2O3 can improve the strength of hydrates,and the optimum proportion of Cr2O3 is O. 5% - 1%. Adding Cr2O3 can broaden the forming temperature of C2.75B1.25A2FS^- zone and fine its grains.
