Phase Identification

 

The phase analysis is performed to determine which crystalline phases are present in the sample. Standard report of phase identification work includes the following:

  • Sample preparation for diffraction experiment

  • Experimental conditions

  • Diffraction raw data file in original and ASCII formats

  • Figure of diffraction pattern showing identified phases with legends 

  • Table with phases present in the sample

 

 

EXAMPLE OF STANDARD REPORT

Phase Identification Report

1. Sample Preparation:

One gram of dry sample was hand-pulverized  and 1μm fraction separated with a microsieve  was used for data collection.

 

2. Experimental Conditions:

Part of pulverized sample was top-loaded into the standard glass sample holder (18mm height and 0.8 mm depth), and compacted with a class slide. Data collection was performed using horizontal goniometer Rigaku DMAX-B powder diffractometer with diffracted beam graphite monochromator. Slits DS=1, SS=1, RS=0.15. Two theta angular range=5-80, Step size=0.05, Step time=5 sec.

 

3. Diffraction data file

Diffraction data file in Binary (Z000111.raw), ASCII (A000111.raw) and MS Excel (X,Y) formats are in CD

 

4. Diffraction pattern showing identified phases with legends

 

5. Phases Table

The sample consists of the phases given in the Table. No other phases or amorphous components are found to be present in detectable quantities.

 

Phases JCPDS
Rutile TiO2 21-1276
Crystobalite SiO2 39-1425
Zincite ZnO 36-1451
