What is x-ray diffraction? X-ray diffraction (XRD) is a non-destructive technique for analyzing the structure of materials, primarily at the atomic or molecular level. It works best for materials that are crystalline or partially crystalline (i.e., that have periodic structural order) but.

The powerful high-temperature and low-temperature sample stages from Anton Paar for in-situ X-ray diffraction (XRD) combine longstanding experience with state-of-the-art technology. Whether for in-situ investigations of phase transitions, solid state/gas reactions or structure determination, XRD solutions from Anton Paar provide the highest level of flexibility in virtually all fields of material research.

  • Several authors have reported that crystalline silicon becomes amorphous upon alloying with lithium. 19 20 21 Limthongkul et al. 20 21 collected high resolution electron microscopy and X-ray diffraction (XRD) data showing the conversion of a crystalline Si electrode into an amorphous Li-Si alloy. They proposed an electrochemically driven solid.
  • (1964) described the original method that is now often used by many researchers. In 1974 Jones et al. Found that osteoblasts moved laterally in vivo and in vitro under different experimental conditions and escribed the migration method in detail. The osteoblasts were, however, contaminated by cells migrating from the vascular.
  • Vacuum X-rays are produced whenever high-speed electrons collide with a metal target. A source of electrons– hot W filament, a high accelerating voltage between the cathode (W) and the anode and a metal target, Cu, Al, Mo, Mg. The anode is a water-cooled block of Cu containing desired target metal.

A vast range of options

Anton Paar offers solutions for all kinds of samples and measurement geometries. You will find the right setup for the investigation of powders, foils and pastes. Depending on your needs, samples can be investigated in reflection or transmission geometry. In addition, a capillary geometry with spinning possibility is available.

Precisely controlled environmental conditions

Using cutting-edge high-temperature and low-temperature chambers for powder XRD and domed stages for four-circle goniometers, you can investigate materials under controlled temperature and pressure conditions. Sophisticated technologies allow for analysis in various atmospheres at temperatures from -193 °C to 2300 °C and at pressures from 10-4 mbar to 100 bar.

Unbeatable accuracy in temperature measurement and temperature homogeneity

Al-si Xrd

The most important of all non-ambient parameters is temperature. Based on smart design and the right choice of materials, Anton Paar provides instruments with high accuracy and reproducibility in temperature measurement. Our environmental heaters are optimized to provide a very homogenous temperature distribution in the sample. This is crucial for obtaining XRD results of superior quality.

User-friendly design

In addition to all mentioned advantages, our instruments are simple to operate. Samples can be applied very easily and the exchange of samples is straightforward. Our instruments fit almost all available diffractometers on the market. Moreover, the temperature controllers are integrated in the software of most diffractometer manufacturers, which enables you to perform fully automatic experiments.

This document provides an introduction to the basics of x-ray diffraction (XRD), aimed primarily at scientists and engineers who are not experts in the field but who are interested in using XRD as a tool.After describing what can be learned from XRD, and how typical XRD instruments are constructed, we go into some depth in describing the analysis of data from x-ray 'area' or 'two-dimensional' detectors.

Experts in the field may identify exceptions to some statements that made in this document, but an effort has been made to strike the right balance between simplicity and accuracy.

For a more in-depth presentation of the same topics, Paul Heiney has produced a series of tutorial videos on X-ray scattering techniques.
