【组织简介】 The International Centre for Diffraction Data (ICDD) is a not-for-profit scientific organization which collects, edits, publishes, and distributes powder diffraction data for the identification of crystalline materials.
The ICDD Mission Statement The International Centre for Diffraction Data will continue as the world center for quality diffraction data to meet the needs of the technical community. ICDD promotes the applications of materials characterization methods in science and technology by providing a forum for the exchange of ideas and information.
Brief History of the ICDD After the development of the First X-ray powder diffraction techniques in the first part of the twentieth century, the need for a central collection of diffraction patterns from known phases became apparent. Following the publication in the late 1930s by Dow scientist of two landmark papers on the archiving and use of powder data for phase analysis, the Joint Committee for Chemical Analysis by Powder Diffraction Methods was founded in 1941 to produce a primary reference of X-ray powder diffraction data, which became known as the Powder Diffraction File?(PDF). This effort was initially supported by Committee E-4 of the American Society for Testing and Materials (ASTM). Over the next two decades, other professional bodies added their support, culminating in 1969 with the establishment of the Joint Committee on Powder Diffraction Standards (JCPDS). The JCPDS was incorporated to continue the mission of maintain the PDF. In 1978, the name of the organization was changed to the Internationa l Centre for Diffraction Data in order to highlight the global commitment of this scientific endeavor.
The ICDD Organization More than 312 scientists from around the world comprise the active membership from which the organization draws its Board of Directors, committees, and subcommittees. The members, who are volunteers, are actively engaged in developments in the field of X-ray powder diffraction and related disciplines. Membership consists of scientists from various affiliations - educational, governmental, and industrial. Semi-annual meetings of the members provide a forum for the exchange of ideas and information pertinent to the scientific community and to organize, plan, and review policies and procedures within the ICDD organization. A paid scientific and administrative staff, located at the Newtown Square, Pennsylvania Headquarters, is responsible for the production and distribution of the various databases offered by the ICDD.
