Collection of 8000+ handbooks and databases for chemistry and engineering, including a large number property data sources. From Material Property Search, enter your material/substance, then browse and select from the list of available properties grouped by category (electrical, mechanical, thermal/thermodynamic, etc.). Data is presented in interactive, downloadable tables, and in some cases interactive graphs. For chemicals, there's also the Open Chemicals Materials Search, NIST's database of thermodynamic data for 27,000 compounds. Click more to see some of the key titles.
