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.

Newly released data 2011/4/1

Thermophysical properties section of NMIJ/AIST is trying to release highly-reliable thermophysical property data measured using the measuring instrument that is traceable to the national standards and their uncertainty were evaluated. We would like to give a special thanks to collaborative research institutes for agreeing to release their data.

About 20 data in all of thermal expansion coefficient, thermal expansion and specific heat capacity are newly released.

<Thermal expansion coefficient (from low temperature to room temperature)>
We released evaluated data with uncertainty information of Niobium, Tantalum, High Manganese Steel, Invar, Niobium Titanium and Titanium.
Link: Details of measurement of thermal expansion (Measurement system of the linear thermal expansion by laser interferometer from extremely low temperatures to room temperature)

<Thermal expansion (from room temperature to high temperature)>
We released the data of Pure Iron, Niobium, Cobalt, Vanadium, Tungsten, Zirconium, Tantalum, SUS316, Hafnium, Nickel, Lead and Platinum.

<Specific heat capacity>
We released evaluated data with uncertainty information of NIST SRM781 Molybdenum.
Link: Details of measurement of specific heat capacity (briefing paper for 2010 Workshops for Solid-State Thermophysical Properties Club)

Updated data matrix of each materials and propertieas by the release of new data are listed below.
