摘要
X‐ray diffraction measurements were used to determine the equilibrium phases for Na2O·y(Al1‐xFex)2O3_m in air for values of x from 0.05 to 0.6 and values of y from 2.5 to 9. The β“ ‐alumina structure was the only single phase observed. At 1400°C, the β” single‐phase region extends for 3.5< y< 7.5 and 0.2< x< 0.55. Precision lattice parameters were determined as functions of x and y.
