“…35 This difference in the crystalline properties should be correlated to the Al 3+ and Ga 3+ ions within the co-alloying garnet that occupy the corresponding octahedral and tetrahedral lattice sites in certain ratios. 36…”

“…35 This difference in the crystalline properties should be correlated to the Al 3+ and Ga 3+ ions within the co-alloying garnet that occupy the corresponding octahedral and tetrahedral lattice sites in certain ratios. 36 According to the Pauling coordination polyhedron rule, 37,38 the relative size of the positive and negative ions directly affects the crystal mode and the coordination polyhedron formation of these ions. Since the radius ratio R Al 3+/R O 2− = 0.382 locates in the range of 0.225-0.414, the Al-O polyhedron prefers to form tetrahedral coordination, while Ga-O forms octahedral coordination because the R Ga 3+/R O 2− = 0.443 locates within 0.414-0.732.…”
