(a) A solid solution is obtained by adding CaO to Ta205. Write two defect equations to describe the defect chemistry that results. (b) Based on the defect models you wrote in part (a) and using the intrinsic defects that are possible in Ta205, discuss how the diffusion of tantalum (Ta) would be affected as CaO is added to Ta2O5. That is, would the addition of MgO cause an increase, a decrease, or no effect on the diffusion of tantalum?
