NIST Superconductors

This database provides evaluated thermal, mechanical, and superconductor property data for high temperature ceramic superconductors. The materials covered include cuprates, bismuthates, and the relatively new borocarbides. Materials are described by specification and characterization information that includes processing details and chemical compositions. Physical characteristics such as density and crystal structure are given in numeric tables.

Properties include superconducting characteristics (Tc, Jc, Hc1, Hc2, etc.), thermal properties (conductivity, expansion, specific heat), mechanical properties (elasticity, strength, toughness), and crystallography (cell parameters, atomic coordinates), methods, procedures, and conditions. The sources of the data (papers published in the years 1987-1996) are fully documented in a comprehensive bibliography.

The database also includes data from the Science and Technology Agency of Japan that, until now, has not been available in English. This unique collection of property and characterization data for single batches of materials resulted from a Japanese study of the processing and properties of high-temperature superconduction materials. The data were provided to NIST as part of an agreement with Japan's National Research Institute for Metals.
