MatNavi is one of the world's largest materials databases of polymer, ceramic, alloy, superconducting material, composite and diffusion.

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.

As of July 1, 2010, the list of registered data had reached 82,000 crystal structures, 55,000 material properties and 15,000 phase diagrams.

What's New
