Why do we do powder diffraction?<br />
Learn where the atoms are (single crystals are better for this, when<br />
available)<br />
Determine the phase(s) in a sample<br />
Measure lattice constants<br />
Quantify the components of a mixture<br />
Learn about physical specimen characteristics such as stress, preferred<br />
orientation or crystallite sizes<br />
Occupancies of elements amongst crystallographic sites<br />
