Show hintHide hint
Think about what technique is used for imaging.
Question 2.
What can XRD patterns help us determine?
Show hintHide hint
Consider the analysis of crystalline materials.
3Question 3.
What does a broad peak in an XRD pattern indicate?
- Large crystallite size

Show hintHide hint
Recall the importance of peak intensity.
Question 5.
Given a set of XRD patterns for three different samples, analyze the differences and infer the possible crystallite sizes and purity levels.
Show hintHide hint
Compare intensities and broadness.
Question 6.
