The glass‐forming regions in the ternary systems M 2 O‐In 2 O 3 ‐GeO 2 (M = Li,Na,K) were determined. The region in each of the three ternaries is less extensive than in either of the analogous systems M 2 O‐Al 2 O 3 ‐GeO 2 and M 2 O‐Ga 2 O 3 ‐GeO 2 ; this behavior reflects the restrictive coordination requirements of the larger In ion. The In 2 O 3 ‐containing glasses exhibit higher densities and refractive indices than the corresponding Al 2 O 3 and Ga 2 O 3 ‐containing glasses. Refractive index and density maxima are observed along lines of constant In 2 O 3 in each of the three alkali indogermanate systems.
