Thermophysical properties of matter database (TPMD)The Thermophysical properties of matter database (TPMD), contains thermophysical properties of over 5,000 materials with approximately 50,000 data curves. This database is searchable by material, by property, or by partial string (name). For all data curves, the material composition, experimental conditions, raw or smoothed data, and references are given. Dynamic graphing capabilities allow users to compare the same property of multiple materials, change scale ranges, and export and import data.
