New Capabilities for 2021

To enhance the value of the PDF® Databases, ICDD has incorporated many new developments for the 2021 product release. Every year, we listen to our customers to create a better product for you. Below are just some of the many value-added developments designed to make the ICDD products more functional and powerful for 2021.

Intensity Scaling for 2D Multiphase Analysis

Intensities are now scaled for ring pattern simulations when doing 2D multiphase analysis.
Understanding Intensity in PDF Database
SIeve+ search results for a three phase unknown.

New Searches and Display Fields

• Refined Formula – A formula derived from the occupancies and site multiplicities of the elements in the atomic coordinates.
• Wyckoff Sequence
Searching the PDF Database
Data mining search results for the Wyckoff sequence “d2 c14”.

Import JADE Projects Directly into SIeve+ for Phase Identification 

Importing into SIeve
Experimental data that was imported and processed in JADE, can now be imported into SIeve+ for complimentary phase identification.

Quick Settings Panel for Pattern Simulations

Results of a PDF Search

Quick settings panel allows the user to dynamically change various simulation settings directly on the graph.

d-spacings Table in SAED Simulation Window

D-Spacing in the PDF Product
New table displays the d-spacings, HKL’s, and intensities for all spots in the SAED pattern simulation window. Spots can be highlighted by clicking on them in the table or directly in the simulation.

ICDD’s Manager of Engineering and Design, Justin Blanton, describes the new SAED features.

Plot Left and Right Y-axes of Data Mining Searches

Temperature Series in Graphed Field

Temperature series graph for GeO2 displaying both temperature (left y-axis) and pressure (right y-axis) as a function of reduced cell volume.

ICDD 2021 Products

PDF-4+ 2021 contains 444,100+ entries. It combines the world’s largest sources of inorganic diffraction data from crystals and powders into a single database. The result is a comprehensive collection of inorganic materials, produced in a standardized format that can be rapidly searched for unknown phase identification.
