NIST Structural Ceramics Database
(www.ceramics.nist.gov/srd/scd/scdquery.htm)
The NIST WWW Structural Ceramics Database (WebSCD) provides evaluated materials property data for a wide range of advanced ceramics known variously as structural ceramics, engineering ceramics, and fine ceramics. The range of materials covers the major series of compounds derived from the ceramic oxide, carbide, nitride, boride, and oxynitride chemical families.

NIST High Temperature Superconducting Materials Database
(www.ceramics.nist.gov/srd/hts/htsquery.htm)
The NIST WWW High Temperature Superconductors database (WebHTS) provides evaluated thermal, mechanical, and superconducting property data for oxide superconductors.

NIST Characterization of Fracture Origins in Advanced Ceramic Materials: Fracture Origin Characterization and the Flaw Catalog
(www.ceramics.nist.gov/webbook/fracture/fracture.htm)
This data site outlines the fracture origin characterization scheme and the linked figures show examples of the most common types of flaws observed in advanced ceramic materials.

NIST Property Data Summaries for Advanced Materials
(www.ceramics.nist.gov/srd/summary/advmatdb.htm)
Property Data Summaries are collections of property values derived from surveys of published data. Thermal, mechanical, structural, and chemical properties are included in the collections. The property values may be typical, evaluated, or validated. Values described as typical are derived from values for nominally similar materials.

NIST Heat Transmission Properties for of Insulating and Building Materials
(http://srdata.nist.gov/insulation/)
The design of heating, refrigeration, and air-conditioning equipment for buildings as well as components of the building thermal envelope depends on the principals of heat transfer theory. This database provides a valuable reference for building designers, material manufacturers, and researchers in the thermal design of building components and equipment.

Mat Web
(www.matls.com/)
MatWeb, the free materials information database with data on 22,154 materials including metals, plastics, ceramics, and composites. MatWeb's database is comprised mostly of data sheets and spec sheets supplied by manufacturers and distributors.

MEMS Material Properties Database
(www.memsnet.org/material/)
The MEMS (MicroElectroMechnical Systems) Material Properties Database includes mechanical properties, electrical properties, optical properties, and other values acquired through a literature search conducted by the MEMS Clearinghouse. This Material Properties database is useful for the design and analysis of MEMS structures and devices by practitioners, researchers and students.

NASA Ames TPSX Materials Property
(http://tpsx.arc.nasa.gov/tpsxhome.shtml)
The Thermal Protection Systems Expert and Material Property Database, or TPSX, is a program which serves as a database for advanced thermal protection material properties. TPSX provides an easy user interface for retrieving material property information in a variety of forms; both graphical and text. The primary purpose and advantage of TPSX is to maintain a high quality source of often-used thermal protection material properties in a convenient, easily accessible form, for distribution to government and aerospace industry communities.

Inorganic Crystal Structure Database (ICSD)
(http://icsd.sims.nrc.ca/icsd/)
ICSD is maintained by Fachsinformationzentrum (FIZ) in Karlsruhe, Germany.
