Muscovite-2M1:PDF Entry 00-058-2034

EBSD Extension

EBSD Extension • Designed to plot K-patterns (Kikuchi & Kossel patterns) • Toggle between gnomonic projection and stereographic projection • For Kossel patterns, up to three Kα1-wavelengths of elements in the chemical formula are used

SAED Extension

SAED Extension • Simulation of freely rotatable SAED patterns from Structures • Import images and apply image processing options • Synchronized Structure Display and Stereographic Projection • Searchable Reflection List with Absences • Measurement Tools: Scalebar, Ruler, Protractor, Indexing Grid • Measure Distances and Angles of clicked spots

BFDH Extension

This module for the BFDH crystal morphology prediction (Bravais-Friedel-Donnay-Harker) represents an extension app that is accessible in PDF-5+. While the original BFDH method for slow growth with D~1/d without structure considerations is the default, one can also choose methods for supersaturation / rapid growth with D~Exp(-kd), after E.Dowty. Furthermore one may promote the presence of faces by including their calculated structure factors Fc(hkl) as "XRD Multipliers", when structure data are available. The option for the Scherrer shape is experimental and is supposed to result in the average crystallite shape actually present in a profile-fitted powder sample.

When applicable, this shows a plot of the PDF entry’s raw diffraction data (also known as PD3 patterns). These are typically nanocrystalline, semicrystalline, or amorphous materials.

Open Bonds Histogram Extension

This tool presents bond distance histograms for selectable element pairs. The distances were calculated from the structure phases in the database. For each structure a minimum distance and the average distance was created for each present element pair within a range based on the radii sum of both elements. A pair of elements may be selected from a periodic table, an element matrix or from a search box. The tabulated distances are then listed and one can select individual entries for the structure display by selecting an entry from the list or by clicking in the histogram.

The 3D Structure shows the three-dimensional representations of molecular structures. Click the play button to see the structure in 360 degrees.
