Inorganic Material Database

Inorganic Material Database (AtomWork)

The Inorganic Material Database aims to cover all basic crystal structure, x-ray diffraction, property and phase diagram data of inorganic and metallic materials from main literature sources.

You have three choices to search data:
1. "Search material" - Search materials by specifying chemical system, chemical formula, substance name, structure type (prototype), Pearson symbol or space group number.
2. "Search Materials having specified property" - Search materials by specifying property.
3. "Search phase diagrams" - Search phase diagrams by specifying chemical system.

Number of open data

crystal structures82,000
material properties55,000
phase diagrams15,000
