Creep characteristics under torsion at elevated temperatures were studied for phosphate bonded alumina. The role of additives like γ-Al203, AlC13 and Al2(SO4) on the creep rate have been evaluated vis-a-vis nature of bonding and related characteristics. It was observed that y-Al203 did not impart superior strength and rather caused a little deterioration. However, A1C13 and A12(S04)3 in appropriate proportions provided significant improvement in strength, with respect to creep characteristics at 1350°C.Thermal analysis and transverse breaking strength data have been utilized in understanding the nature of the high temperature reactions, and the results have been augmented with x-ray analysis and electron micrographs.The distribution of aluminium phosphate and the ratio of A1P04A1(P03)3 are the main factors elucidating the differences in high temperature strength. © 1979 Taylor & Francis Group, LLC.
