Chemically Reacting SiO2, H2O, and SiO2 + H2O Systems under High Pressure and Temperature
When we simulate dynamic physical processes with a computer, we must know the equation of state (EOS) for the materials in question. The more accurate the equation of state, the closer the program can simulate the physical reality. This study was undertaken to obtain equation of state expressions for silicon dioxide (SiO2), water (H2O), and SiO2 + H2O mixture. Such expressions are of primary interest to the designers of underground nuclear tests because cavity size, pressure, and other seismic disturbances of the explosion depend on the state properties of rock media. To date, a rather crude EOS expression (such as an ideal-gas law) has been used to satisfy an actual need.
