Research (preliminary values work in progress)Ĭertain commercial equipment, instruments, or materials are identified in this document to specify adequately.

Evaluated (basic acceptance criteria satisfied).

Validated (confirmed via correlations and models).

The data evaluation levels used throughout the NIST Ceramics WebBook are: Of materials and are not necessarily the best or most appropriate valuesfor any particular material. Typical values are only representative of trends of values commonlyfound for a general class Values described as typical are derived from values for nominally similar materials. The property values may be typical,Įvaluated, or validated. While studies of particular properties survey one property across many materials. Studies of specific materials typically include thermal, mechanical, structural, and chemical properties, These collections typically focus on either one material or one particular property.

Property Data Summaries are collections of property values derived from surveys of published data.

In all cases, the sources of the data are fully documented in a detailed bibliography. All measured values are evaluated and supported by descriptions of the measurement methods, procedures, and conditions. Physical characteristics such as density and crystal structure are given in numeric tables. The materials are described by specification and characterization information that includes processing details and chemical compositions.

The range of materials covers the major series of compounds derived from the ceramic oxide, carbide, nitride, boride, and oxynitride chemical families. The NIST These characteristics form the basis for applications of these materials in high-temperature, energy-efficient heat exchangers, advanced engine designs, bearings, wear resistant parts, and stable electronic substrates and electronic packaging.
