NIMS Materials Database

NIMS Materials Database

The NIMS Materials Database (MatNavi) aims to contribute to the development of new materials and the selection of materials. MatNavi includes Polymer DB (chemical structures, polymerization, processing, physical properties, NMR spectra, etc.), Inorganic MaterialDB (crystal structures, phase diagrams, physical properties, etc.), Metallic Material DB (density, elastic constants, creep characteristics, etc.) and Computational Electronic Structure DB (band structures obtained by first-principles calculations, etc). It also offers applications such as the Composite Design & Property Prediction System. If you register, you can search and browse various databases for free.

Process for getting started

The following three procedures are required to use MatNavi service. (Registration and Application Manual)

(1) DICE Account User Registration
  In principle, a user is an individual who belongs to an organization.
  Please perform "DICE Account User Registration" using the e-mail address provided by your organization.

(2) Domain Name Registration of E-mail Address
  When applying to use MatNavi, identity verification based on the e-mail address is required.
  Please make sure that the domain name of your e-mail address is registered in our management list.
  If the domain name is not registered, please apply by your organization's domain administrator(s) or a person who has been approved by the domain administrator(s).
   - How to check the domain name registration status (FAQ 4)
   - Details of the application procedure

(3) MatNavi Usage Application
  If the domain name is registered, you can continue to apply for MatNavi usage.
   - MatNavi Usage Application (Please use a computer browser.)

Mass downloading of data is prohibited

Web scraping of data is prohibited!
The acquisition of large amounts of data, whether by manual or mechanical means, is prohibited by the MatNavi Service Terms of Use.
User accounts will be suspended when there is a possibility of data access that is deemed to be a violation.
Please comply with the terms of use, as the MatNavi database service will no longer be viable.




New Users:

The use of MatNavi is free. (Free of charge).
"DICE account user registration" and "MatNavi usage application" are required.

Registered Users:

Please select a database and login on each page.
A DICE account (ID and password) is required to login.


Basic Properties


The Polymer Database (PoLyInfo) contains information on polymer names, structures, properties, measurement conditions, polymerization methods, molding methods, etc. extracted from scientific literature.


The Inorganic Materials Database (AtomWork) contains information on crystal structures, X-ray diffraction, properties, and phase diagrams extracted from scientific literature.


The Computational Phase Diagram Database (CPDDB) contains information on the Gibbs energy functions of the phases are accumulated in a form of TDB (Thermodynamic DataBase) files, which are obtained from the CALPHAD-type thermodynamic assessments.


The Computational Electronic Structure Database (CompES-X) contains information on predicted by the first-principles calculations (VASP) for crystalline inorganic compounds.


The Diffusion Database (Kakusan) contains information on the basic diffusion data (diffusion atom, diffusion coefficient, activation energy, etc.) of metallic and inorganic materials from scientific literature.

The Composite Design & Property Prediction System (CompoTherm) is an advanced simulation tool for searching for candidate composite materials with optimal thrermo-physicical properties and structures.


The Metal Segregation Prediction System (SurfSeg) is designed to simulate surface or interface segregation in the following four cases: surface segregation in film/substrate, surface segregation in dilute alloy system, interface segregation at film-substrate interface, and interface segregation at alloy-substrate interface.


Interface Bonding Prediction System (InerChemBond) is a system that predict of interface chemical bonding between metal oxide (AxOy) and metal (M) or alloy (MB dissolved in MA).
