XRD

XRD to identify crystal structure

🎯 Difficulty ★★☆ Medium ⏱ Duration About 1–2 h 🎯 Use Use X-ray diffraction to identify phases, crystallinity, and structure.

📖 Principle

X-rays diffract off crystals to produce peaks that identify the phase.

1

Grind and mount

15 min

Grind powder to micrometer scale and press flat into the holder well.

💡 Tip　Level the sample with the holder

2

Load and align

10 min

Place on the diffractometer stage and verify height alignment.

💡 Tip　Height error shifts peak positions

3

Set scan parameters

5 min

Set 2θ range, step size, and scan time, then collect.

💡 Tip　Slow scan improves peak precision

4

Analyze pattern

30–60 min

Match peaks to PDF cards to index phases, lattice, and crystallinity.

💡 Tip　Search against standard card library

⚠️ 5 Common Beginner Mistakes

① Unleveled sample shifts peaks
② Coarse grains give split peaks
③ Preferred orientation skews intensity
④ Overly slow scan wastes time
⑤ Wrong card matching misidentifies phase

❓ FAQ

+Peaks don't match the card?

Check alignment, sample flatness, and possible doping.

+What do broad peaks mean?

Small crystallite size or low crystallinity.

+Quantitative analysis possible?

Yes, via Rietveld refinement of the full pattern.
