Clay Analysis

“Clay Analysis”

Speaker: Anja Dosen

Clays and clay minerals are commonly found in sedimentary rocks and soil. Clays have been in use for centuries, they can be found in ceramic and building materials, catalysts, health and beauty products, nanomaterials and nanocomposites,
air filters, etc.

Clay minerals are layer silicates belonging to the phyllosilicate group. They consist of tetrahedral and octahedral sheets. Tetrahedral sheets consist of infinite layers of SiO4 and AlO4 tetrahedra while, octahedral sheets lie on top of tetrahedral layers and consist of di- or tri-valent cations coordinated with oxygen atoms. Clay minerals usually contain variable amounts of calcium, iron, magnesium, alkali metals, and other cations. Differences in T-O arrangements result in different groups of clay minerals. Due to both similarity and structural diversity, clay minerals are difficult to identify. Powder XRD remains one of the major tools in their identification as each scan represents an average of millions of clay particles.

In this webinar, you will see some of the major steps in clay mineral analysis, like the importance of sample preparation and different methodologies like size separation, preparation of oriented and unoriented samples, and different sample treatments that help in phase identification.

Clay minerals are layer silicates with variable amounts of calcium, iron, magnesium, alkali metals, and other cations. Differences in structural arrangement result in different groups of clay minerals. Due to both similarity and structural diversity, clay minerals are difficult to identify. Powder XRD remains one of the major tools in their identification.

In this webinar, you will see examples of clay analysis using the carefully curated clay subfile in the PDF-5+ database. We will show the possibilities for the identification of both oriented and unoriented samples and the modeling of oriented clays using JADE.

 

New Features of the 2024 PDF Databases

“New Features of the 2024 PDF Databases”

Speaker: Justin Blanton


To enhance the value of the PDF software, ICDD has incorporated many new developments for the 2024 product release. The software allows users to search for 2D structures using a list of templates. Graphing capabilities have been enhanced by implementing automatic vertical zooming, as well as adding a gradient color fill option for x-y plots. PD3 patterns (raw data) can be displayed directly in the search results table for convenient viewing. New file formats such as Rigaku *.asc and *.rasx can now be imported for phase identification. When importing multiple 2D diffraction patterns, the images are dynamically displayed during import with a red line indicating the integration progress. SIeve/SIeve+ allows the user to hide irrelevant matches during analysis and perform a single peak search for trace phases. These are just some of the many value-added developments designed to make the ICDD products more functional and powerful for 2024.

Pharmaceutical Characterization using PDF-4/Organics

“Pharmaceutical Characterization using PDF-4/Organics”

Speaker: Tim Fawcett, Former ICDD Executive Director

The analysis of pharmaceuticals and pharmaceutical formulations can be difficult. The materials are often needles or platelets that tend to orient. Many pharmaceuticals are weakly scattering and poor absorbers so instrumental errors such as specimen displacement and transparency are common. A typical tablet formulation can contain noncrystalline, nanocrystalline and amorphous materials as part of the product design so typical single crystal databases have difficulty with the analysis. The PDF-4/Organics database Release 2022 is designed to overcome these difficulties through a combination of having the right types of data, with embedded applications and analysis software. This database has been specifically designed, and subsequently developed, over the last 20 years for pharmaceutical analyses. In this webinar we will explore design features and analysis applications.

In this webinar, you will learn:

  1. Data mining for specific compounds/polymorphs.
  2. Subfiles and data types.
  3. Instrumental corrections.
  4. Crystallite size and orientation adjustments.
  5. Identification by Search/Match and Similarity Index.
