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.

MatNavi user registration / authentication system updates : Needs re-registration

We updated the user registration and authentication systems of MatNavi to improve its security on December 1, 2020.
The old registered information completely discarded, and thus logging into the newly updated system with old information not be possible.
Users who have registered to the old system (registered before November 30) must register again on the newly updated system.
We apologize for the inconvenience caused by this update and ask for your cooperation.
