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.

In total more than 11,500 property data (including machine characteristic and optical characteristic) for about 3,600 materials are available for free. Please access our database called "TPDS-web" via links in this page.

-InetDBGV ver3.0.13 release-

Release date:2011/5/12

New functions in version 3.0.13

1. Enhancement of material shape information recording

It is now possible to record and release material shape information of grade level, lot level and sample level.
Following example shows a shape information of aluminum-magnesium alloy rod-shaped sample (10 cm in length and 0.4 cm in radius) recorded in specimen level.

2. Crystal information available

It became possible to record and release detailed information on grain size, crystalline state, crystal system, etc.
Following example shows a sample of shape: thin film, crystal grain shape: ellipse, type of crystal: F.C.C..
It is possible to record specific information such as wurtzite-type or NaCl-type for type of crystal.
