Additional Resources to Find Properties

  • ASM Alloy Phase Diagram Database
    Contains more than 40,300 binary and ternary phase diagrams, each with their associated crystal and reaction data. Users can search for phase diagrams either via the database content tree, the element search or the search slot. A video tutorial can be found here.
  • ChemIDplus
    ChemIDplus, from the National Library of Medicine, is a free database of some 400,000 chemical compounds. Records consist of name, synonyms, CAS number, molecular formula, properties, and direct links to biomedical resources.
  • ChemExper Chemical Directory
    The ChemExper Chemical Dictionary contains basic properties and spectra, as well as materials safety data sheets. Data is supplied by users, so, exercise caution when using.
  • ChemSpider
    ChemSpider is a free chemical database with access to more than 26 million structures. Both experimental and calculated properties are available including standard ones like specific gravity; melting, boiling, and flash points; refractive index and solubility; as well as appearance, stability, toxicity and safety data.
  • DIPPR Project 801
    The Knovelized 2011 edition of DIPPR 801 is a renowned source of evaluated process design data of physical, thermodynamic, and transport properties for industrially important chemicals used in chemical process and equipment design.
  • Matweb
    MatWeb is a searchable database of properties of more than 86,000 materials. Included are property information on thermoplastic and thermoset polymers, metals, ceramics, semiconductors, fibers and other engineering materials.
  • NIST Chemistry WebBook
    The database contains chemical and physical property data compiled by the National Institute of Standards and Technology (NIST). Up to 45 thermochemical, thermophysical, and ion energetics properties are available for over 40,000 compounds.
    To browse other NIST databases, visit the NIST Data Gateway, which provides information for over 94 NIST databases including the NIST Chemical Kinetics Database, the NIST Elemental Data Index or the Ceramics Portal. Note that some other NIST databases might not be freely accessible.
  • Ullmann's Encyclopedia of Industrial Chemistry
    A comprehensive encyclopedia of science and technology as applied to industrial chemistry; includes information on physical and chemical properties.
  • Wolfram|Alpha: Computational Knowledge Engine
    Wolfram|Alpha contains a wide variety of data on many chemical compounds. While the source for this data are listed, you cannot be certain where a particular information came from. However, the sources for individual results can be requested from Wolfram|Alpha via a web form.
