PHASE DIAGRAM OF THE SYSTEM MgAl$sub 2$$O$$sub 4$-NdAlO$sub 3$
The phase diagram of the system MgAl/sub 2/O/sub 4/-NdAlO/sub 3/ was studied. Specimens containing 0, 5, 10, and so on, mole% of one component (2 mole % intervals in the vicinity of the eutectic) were prepared under argon from carefully mixed gamma -Al/sub 2/O/sub 3/, MgO, and Nd/sub 2/O/sub 3/ in a high- temperature electric vacuum microfurnace with a tungsten heating element. After equilibrium was attained, the samples were hardened and subjected to crystallo- optical, metallographic, and x-ray analyses. The system forms no chemical compounds or solid solutions and is of the simple eutectic type, with the eutectic at 1835 deg C, 62 mole % MgAl/sub 2/O/sub 4/ and 38 mole % NdAlO/sub 3/. (OTS)
