Often used as protective coatings of gas turbine or engine components, nuclear materials and medical devices, many nanostructured materials are known to have several structural crystalline phases, according to the synthesis temperature and pressure, such as diamond and zirconium oxide.
Most nanostructured materials are obtained through gas-solid reactions, which are controlled both by kinetic and by thermodynamic factors.
Thermodynamic data for many oxides, nitrides, carbides and other high-temperature phases are currently available either in material science source (JANAF Tables, handbooks, etc) or rather specialized source (Thermocalc Database).
For a better understanding, and due to size restrictions, the paper focuses on diamond nanostructured materials.
