摘要：

The compatibility of A1(2)O(3) and LaPO4 at temperatures up to 1600 degrees C is examined. Provided the ratio of La to P was close to 1:1, no reactions were observed after 200 h at 1600 degrees C. Moreover, the Al2O3LaPO4 interface remained sufficiently weakly bonded to cause deflection of cracks, as reported previously. In the presence of excess P or La, reactions occurred as expected, forming AlPO4, in the case of excess P, and LaAlO3 and LaAl11O18 in the case of excess La.
