Thermodynamic Properties and Equation of State for Solid and Liquid Aluminum

High-temperature equations of state for solid and liquid aluminum were constructed herein using experimental data on thermodynamic properties, thermal expansion, compressibility, bulk modulus sound velocity measurements, supplemented with phase diagram (melting curve). The entire set was optimized the temperature-dependent Tait equation over a pressure range up to 800 kbar temperature from 20 K melting point 3800 aluminum. dependence thermophysical parameters described by an expanded Einstein model. resultant describe well totality within measurement errors individual variables.
