AIST>RIO-DB>Network Database System for Thermophysical Property Data

Network Database System for Thermophysical Property Data is developed and run by AIST, and is available for free. Thermophysical properties data (ex. Thermal conductivity, thermal diffusivity, heat capacity, density, surface tension and vapor pressure) for liquid, solid and melts are stored in this database.

Browsing DB by Web browser: TPDS-web/full(for high speed internet), TPDS-web/light(for low speed internet)
DB browsing by exclusiive software: InetDBGV

User registration is recommended!

In total more than 9300 property data (including machine characteristic and optical characteristic) of about 3600 materials are available for free. Please access our database through DB browse items in right frame.

Registered user can use InetDBGV browsing software and access to much more data than guest user. User registration is highly recommended.
