How to Use Pcpdfwin Software for XRD Matching of JCPDS ICDD Data


How to Use Pcpdfwin Software for XRD Matching of JCPDS ICDD Data




Pcpdfwin is a software application that allows users to search and match X-ray diffraction (XRD) data with the Powder Diffraction File (PDF) database from the International Centre for Diffraction Data (ICDD). The PDF database contains over one million material data sets with diffraction, crystallographic, bibliographic, and physical properties information. The PDF database is designed to solve material problems by providing reliable and comprehensive data for phase identification and characterization.

In this article, we will show you how to use Pcpdfwin software for XRD matching of JCPDS ICDD data in a few simple steps.


  • Install Pcpdfwin software on your computer. You can download it from the ICDD website[^1^] or from other sources. You will also need a license key to activate the software.



  • Launch Pcpdfwin software and select File > Open Database. Choose the PDF database that you want to use, such as PDF-4+, PDF-2, or PDF-4/Organics. You can also select multiple databases if you want to search them simultaneously.



  • Select File > Open Data File and choose the XRD data file that you want to match. The data file should be in ASCII format with two columns: 2-theta and intensity. You can also enter the experimental conditions, such as wavelength, divergence slit, and sample displacement.



  • Select Search > Search/Merge and choose the search parameters, such as peak position tolerance, peak intensity threshold, and figure of merit. You can also select the search criteria, such as chemical formula, crystal system, space group, or cell parameters.



  • Click on Start Search to begin the matching process. The software will display a list of possible matches ranked by figure of merit. You can view the details of each match by clicking on it. You can also compare the experimental and calculated patterns by selecting View > Pattern Overlay.



  • Select File > Save Results to save the matching results in a text file or a report file. You can also print or export the results to other formats.



Pcpdfwin software is a useful tool for XRD matching of JCPDS ICDD data. It can help you identify and characterize unknown materials by comparing them with the PDF database. However, you should also use your own judgment and knowledge to verify the results and avoid false positives or negatives.


XRD is a technique that uses X-rays to probe the structure of materials. When X-rays interact with a material, they are scattered by the atoms in a specific pattern that depends on the arrangement and spacing of the atoms. By measuring the angles and intensities of the scattered X-rays, we can obtain information about the crystal structure, phase composition, lattice parameters, strain, texture, and other properties of the material.


XRD is important because it can help us understand the properties and behavior of materials at the atomic level. For example, XRD can help us identify the phases and compositions of minerals, alloys, ceramics, polymers, and other materials. XRD can also help us determine the crystal structure and symmetry of new materials, such as nanomaterials, superconductors, and biomolecules. XRD can also help us monitor the changes in structure and phase of materials under different conditions, such as temperature, pressure, stress, or chemical reaction.


Pcpdfwin software is not the only software that can perform XRD matching of JCPDS ICDD data. There are other software applications that can do similar tasks, such as JADE, HighScore, Match!, and others. Each software has its own advantages and disadvantages, such as features, functions, user interface, speed, accuracy, and compatibility. You should choose the software that suits your needs and preferences best. 0efd9a6b88
