Abstract
The formation of the spinel CuAl2O4 from the oxides CuO and Al2O3 has been studied at 1000 and 950°C in air by measuring the fraction reaction completed as a function of time. In the experiments the molar oxide ratios were CuO/Al2O3 = 0.5, 1.0 and 2.0 and the grain size for CuO was 1–3 μ throughout while for Al2O3 fractions of 40–60 μ, 71–100 μ and 100–125 μ, were used. The rate of reaction could be explained quite well assuming a three‐dimensional diffusion mechanism.Keywords
