Precise information on the crystalline properties of materials is essential for scientists from research institutions working in the fields of crystallography, mineralogy, geology, materials science and inorganic chemistry need. This information can solve issues in materials science, help predict and optimize material properties, and improve analytics. A prominent example is research on and the further development of crystalline inorganic materials in photovoltaics. The searchable data published in ICSD have been evaluated and indexed. These data can also serve as a basis for data mining.
