Single-phase structure confirmation from PXRD

An experimental powder pattern was compared with a candidate crystal model, followed by whole-pattern fitting and lattice refinement to assess structural consistency and residual unmatched features.

Single-phase PXRD structure confirmation fitting plot — Representative final plot. The case is shown to document the analysis route and delivery style, not to disclose proprietary sample details.

Questions addressed

Does the candidate model explain the pattern?

Calculated reflection positions and full-profile behaviour were evaluated against the measured data, including the difference curve.

Has the lattice changed?

Refined cell parameters provide a consistent way to discuss peak shifts or expansion and contraction when measurement quality supports the comparison.

What this result does not prove alone

A consistent powder pattern supports structural assignment, but does not by itself prove a unique atomic configuration, dopant site or defect model. Those conclusions require adequate data sensitivity and, where appropriate, complementary evidence.

The final wording is calibrated to the evidence so that phase confirmation is not overstated as full atomic-structure determination.
