Abstract

X‐ray powder patterns have been used to measure the thermal expansion of (a) nickel oxide, (b) nickel aluminate, and (c) nickel oxide containing alumina and ignited at 1300°C in air. The results show that any solid solution that occurs must be restricted to less than 1 mole % of the solute. An X‐ray line‐broadening effect was found in the ignited and quenched nickel oxide containing alumina. This is attributed to heterogeneous lattice strains associated with a limited solid solution of nickel aluminate in nickel oxide at ignition temperatures and reprecipitation during quenching to room temperature.
