(a) Draw a projection of the structure on the x-z plane. (b) What is the coordination environment of (i) Sr, (ii) Ti, (iii) O. (c) Calculate the Sr-O and Ti-O bond lengths. Calculate the density of SrTiO3.

The crystal structure of SrTiO3 is cubic, with a unit cell edge a = 3.90 Å. Calculate the expected 2θ positions of the first three peaks in the diffraction pattern which correspond to the planes (100), (110), (111) if the radiation is Cu Kα(λ= 1.54 Å).

SrTiO3 The structure factor represents the scattering of x-rays from the periodic arrangement of atoms within a particular crystal structure. Using the atomic positions for the atoms within the unit cell, you can calculate the (hkl) planes will result in constructive interference conditions from the lattice and their relative intensities.
