1 Application Report Dr. Ya-Ching Yang phone: (02) #205

2 Experiments with New D2 PHASER The measurements were made with the D2 Phaser diffractometer (θ-θ). Every samples were measured in the Bragg- Brentano geometry. The LynxEye fast linear detector was used for all measurements. The powder samples were prepared in a standard PMMA sample holder (cavity diameter 25 mm and 1 mm depth). The bulk samples were prepared in a standard PMMA sample holder (cavity diameter 40 mm and 5 mm depth). The few amount powder samples & thin film samples were prepared in a standard Si low background sample holder. PMMA sample holder Si Low Background Sample Holder

20 A phase identification was performed with the Diffrac.EVA software in combination with the PDF4+ database. Obviously, the sample contains two allotropic (alpha and beta) forms of Si3N4. Sample Si3N4_1

21 Adjusting the height of the sticks to the measured intensity, a semi-quantitative estimation of the phase is automatically performed (based on I/Icor coefficients). The sample contains about 88.8 wt% alpha- Si3N4 and 11.2 wt% beta-Si3N4. Sample Si3N4_1

22 A phase quantification (based on the Rietveld method, see next slides) was performed using the DiffracPlus TOPAS software. The final phase ratio (in wt%) is displayed on the picture. It is in very good agreement with semi-quantitative result. Quantitative Analysis in TOPAS

23 A phase identification was performed with the Diffrac.EVA software in combination with the PDF4+ database. The sample contains two allotropic forms of SiC: 6h and 15R. Traces of quartz and silicon could also be detected. Sample SiC

24 Adjusting the height of the sticks to the measured intensity, a semi-quantitative estimation of the phase is automatically performed (based on I/Icor coefficients). The sample contains about 85 wt% SiC-6H, 14.3 wt% SiC-15R and traces of quartz and silicon. Sample SiC
