Description
Strontium germanate can be formed by firing the
oxides together at about 850°C:
SrO + GeO2 + heat?SrGeO3
The SrGeO3 perovskite crystal structure is formed by
the Ge cations filling 25% of the octahedral holes in the
cubic close-packed SrO3 array as an octahedron. In the
ideal cubic structure, each Sr cation is coordinated to
12 O-anions and each GE cation is coordinated to six
O-anions.
