[@Uhanna64]

Hello professor Thank you very much for nice lectures, I have a question (minute 12). How we can say the example crystal PbTiO is primitive while it has Ti in its body?

[@bhadeshia123]

+Uhanna64 Because the environment around a lattice point must be idential. The titanium atom is not a lattice point because its surroundings are different from those at the corners of the lattice point. See the earlier lectures in this series.

You can find that information on: www.phase-trans.msm.cam.ac.uk/teaching.html Look for lecture notes, Crystallography.
