  • The data, consisting of graphical diagrams, provide equilibrium chemical and structural behaviors. NIST Standard Reference Database 31 disseminates readily accessible and searchable data electronically in partnership with the American Ceramic Society ( ACerS ).
    Every deliberate effort to develop a new ceramic or to improve processing begins with chemical composition and the conditions (temperature, pressure) under which pure compounds and their mixtures are stable (an equilibrium phase diagram).
    In the absence of such information, developers must resort to trial-and-error approaches or conduct their own studies to obtain the data.
  • NIST Standard Reference Database 31, published from 1964 to 1992 as the well-known Phase Diagrams for Ceramists "blue books," is the result of a long-standing collaboration between NIST and The American Ceramic Society to develop and maintain a state-of-the-art database of critically evaluated phase equilibria data for industrial and academic customers.In 1992, the title was changed to the more general "Phase Equilibria Diagrams" to emphasize that the data are useful to the broader inorganic materials community.
    Standard Reference Database 31 serves as the only "Mapquest" database for ceramic and inorganic systems: The diagrams provide maps of the equilibrium chemical and structural behaviors exhibited by materials and provide critical starting information for the rational design of materials-processing schemes and for quality assurance efforts and optimization of the physical and chemical properties of advanced materials.
  • The 2012 release is the largest-ever update of Standard Reference Database 31 and includes 900 new figures with more than 1,400 new phase diagrams, in addition to all the information previously printed in the 21 hard-copy volumes of the series. The new content includes experimental and calculated data for an unprecedented range of non-organic material types, including phosphates (batteries, laser and other optoelectronic materials), chalcogenides (semiconducting sulfides, selenides and tellurides for thermoelectrics, optoelectronics and photovoltaics), pnictides (nitrides, phosphides, arsenides and antimonides for bandgap-engineered optical materials, electron-transport devices, sensors, detectors, photovoltaics and thermoelectrics), halides (nuclear applications, scintillation detectors), and oxide/metal+oxide systems (electrode processing, catalysis, electroceramics, magneto-resistors, thermistors, capacitors, nuclear fuel and waste, ionic conductors, and fuel-cell electrolytes).
