XRD is a non-destructive test method used to analyze the structure of crystalline materials. XRD analysis, by way of the study of the crystal structure, is used to identify the crystalline phases present in a material and thereby reveal The chemical composition information. JCPDS does not exist now. It has not existed since 1978. It is now known as ICDD. These particular files have never been, are not, and never will be free; it a commercial only database. There are other free databases, however. Vikas has given you a starting point.

Powder Diffraction File is a trademark of the “JCPDS (Joint Committee on Powder Diffraction Standards)-International Centre for Diffraction Data”.In 1978, the name of the organization was changed to the “International Centre for Diffraction Data” in order to highlight the global commitment of this scientific endeavor. Here, you need to purchase the database.

Some free databases are collected:

1. COD (Crystallography Open Database):

COD is an open-access database, and you can freely obtain all data contained in it. You can download cif files and then you can use mercury to plot structure models and save reflection list and xrd calculated pattern.

2. The American Mineralogist Crystal Structure Database:

This site is an interface to a crystal structure database that includes every structure published in the American Mineralogist, The Canadian Mineralogist, European Journal of Mineralogy and Physics and Chemistry of Minerals, as well as selected datasets from other journals. The database is maintained under the care of the Mineralogical Society of America and the Mineralogical Association of Canada, and financed by the National Science Foundation.

3. DASH: (Cambridge Structural Database System (CSDS)):DASH is a versatile and interactive package for solving crystal structures from powder diffraction data. DASH solves structures by simulated annealing of structural models to indexed diffraction data and features a helpful wizard to guide you through the entire structure solution process.

Some of Paid databases:

1. The International Centre for Diffraction Data® (ICDD®):

ICDD (JCPDS is now called ICDD) is a non-profit scientific organization dedicated to collecting, editing, publishing, and distributing powder diffraction data for the identification of materials. The membership of the ICDD consists of worldwide representation from academe, government, and industry. The Powder Diffraction File™ (PDF®) is the only crystallographic database that is specifically designed for material identification and characterization. It is an analysis system that is comprised of crystallographic and diffraction data. The only crystallographic database organization in the world with its Quality Management System ISO 9001:2015 certified by DEKRA.

2. HighScore Plus:The ideal tool for crystallographic analysis and more. Whether you are interested in improved process control, or doing research and development, understanding your materials starts very often with understanding the powder diffraction pattern. After identification of all phases present in your sample with Malvern Panalytical’s HighScore, this all-in-one software suite with the Plus option continues to support you with your analysis. Whether your focus is on quantification with or without the Rietveld method, profile fitting, or pattern treatment; HighScore Plus is the solution and helps you performing your daily analyses.
