Material Properties Data and References

This site collects information for development of open-access databases/repositories related to material properties under varying pressures and temperatures. Target audiences are the materials high pressure communities in geosciences, physics, and engineering and the planetary impact processes communities.

What kinds of data are desired for these communities?

For minerals and rocks/ices and melts/fluids properties desired in open access repos:

• Equations of state (P-V-T): static, dynamic lab data and ab initio calculations; phase diagrams
• Thermophysical properties: heat capacities, electrical and thermal conductivities, Grueneisen parameters, thermal expansion, sound speeds; opacities
• Crystallography: structure parameters, elastic and shear moduli
• Spectroscopic/optical properties: absorption/transmission spectra; index of refraction; pressure range for transparency under shock or ramp
• Magnetic properties
• Rheological properties: (quasi-static) failure; HEL; viscosity; fragmentation
• Mixtures/compounds: mixture theory; phase diagrams; porosity?

In progress below:

• collect available databases and references for material properties (emphasis on geo-materials and lab standards)
• Collect information about open access standards and initiatives
• Explore other examples of database structures and data format standards:
• XML format examples below (thermoML; chem CXML)
• JSON format also used for no-SQL databases. E.g. MongoDB in materialsproject.org

(not including superconductors, organic materials,….)
