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.

Browsing system by web browser

-TPDS-web/full

It is possible to use simple search or data comparison of the browse system without depending on a certain OS or browser.

-TPDS-web/light

TPDS-web lightweight version can be used via IE, GC, and have a light load.AJAX/light

Exclusive soft for browsing DB

-InetDBGV

InetDBGV is the database browsing software can be used by installing onto your Windows OS. Compared to the web browser version, it has several functions corresponding to higher and technical needs like property search or 3D graph plot using a large quantity of data.
