• The diffusion of trivalent gallium into the rock salt lattice of MgO has been investigated. This has been a first attempt at studying a diffusion process which involves both defect formation and the formation of a new phase, MgGa_2O_4, with a moving interface. The study was performed on pre-sintered MgO and β-Ga_2O_3 pellets. The Wagner treatment of Fick's second law was used in the analysis and it was subjected to certain boundary conditions and approximations. The diffusion coefficient was determined from the slope of the linear region of the inverse complementary error function of the concentration as a function of penetration. The departure from linearity in the region of greatest penetration indicates that initially diffusion takes place in the grain boundaries. The region of linear dependence takes place in the later states of diffusion when bulk diffusion predominates. The mean diffusion coefficient as determined from three different anneal times at 1500℃ was 7.53±0.25×10^<-10>cm^2/sec.
