Materials Data on AlSiO3 by Materials Project

Abstract

AlSiO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Al is bonded to twelve equivalent O atoms to form AlO12 cuboctahedra that share corners with twelve equivalent AlO12 cuboctahedra, faces with six equivalent AlO12 cuboctahedra, and faces with eight equivalent SiO6 octahedra. All Al–O bond lengths are 2.52 Å. Si is bonded to six equivalent O atoms to form SiO6 octahedra that share corners with six equivalent SiO6 octahedra and faces with eight equivalent AlO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Si–O bond lengths are 1.78 Å. O is bonded in a linear geometry to four equivalent Al and two equivalent Si atoms.
