Toplan, Volkan Gunay] The grain growth kinetics in the 0, 2 and 4wt.% TiO2 added ZnO-6wt.% Bi2O3 system was studied using the simplified phenomenological grain growth kinetics equation $$G^n = k \cdot t \cdot \exp ( - Q/R \cdot T)$$ 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 5 and 218kJ/mol, respectively. The addition of the TiO2 to the ZnO-6wt.% Bi2O3 system inhibited the ZnO grain growth. At 2 and 4wt.% TiO2 additions, the apparent activation energies were calculated as 467 and 346kJ/mol, respectively. The addition of TiO2 to the system inhibited the grain growth of ZnO ceramics.
