Strontium titanate is a semiconducting material that crystallizes into a perovskite structure. The Sr atom sits on the corner of a cube, the O atoms are on the face- centered sides of each cube and the Ti atom is at the center. The lattice parameter is 0.39 nm. 1. What is the Bravais lattice of strontium titanate? 2. Calculate the density in if Msr = 87.62 S, Mti = 47.87 and Mo = 16.

Crystallography

Crystallography is the category of science that focuses on the atomic and molecular arrangements with their bonding constituting the crystal structure. It is derived experimentally and originated in the year 1912. It is a combination of two words; those are crystal, meaning a cold drop, and graph, meaning writing.
