The grain growth kinetics in the 0–5 wt% MnO-added ZnO—6 wt% Bi2O3 system was studied using the simplified phenomenological grain growth kinetics equation Gn = K0.t. exp(−QRT) together with the physical properties of the sintered samples. The grain growth exponent value (n) and the apparent activation energy for the ZnO—6wt% Bi2O3 system was found to be 5 and 200 kJ mol−1, respectively. These values support the published data for the grain growth mechanism of the ion diffusion model in liquid… CONTINUE READING
