AIST>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


More than 11,800 property data (including mechanical and optical properties) for about 3,600 materials are available for free. Please access our database browsing system on the web, "TPDS-web" via links on the right panel of this page.

Newly released data 2016/04/13

104 data are newly available. Thermal conductivity and thermal diffusivity for DLC(Diamond like carbon) and CVD(Chemical Vapor Deposition) Diamond, thermophysical properties for wide band-gap semiconductors such as GaN and InN, and thermophysical property depends on both pressure and temperature for minerals.
