| Abstract: | The solubility of quartz in water from 25?? to 900??C at specific volume of the solvent ranging from about 1 to 10 and from 300?? to 600??C at specific volume of the solvent ranging from about 10 to 100 is given by an empirically derived equation of the form: log m = A + B(log V) + C(log V)2 where m is the molal silica concentration, V is the specific volume of pure water, and A = -4.66206 + 0.0034063T + 2179.7T-1 - 1.1292 ?? 106T-2 + 1.3543 ?? 108T-3B = -0.0014180T- 806.97T-1C = 3.9465 ?? 10-4TT is temperature in kelvins. The experimental data used in formulating the empirical relation ranged in pressure from 1 bar at 25??C to about 10,000 bars at 900??C, and the lowest pressure in the low-density steam region was about 30 bars. According to the above equation, the average difference in molality between 518 measured and calculated solubilities is -0.016 m with a standard deviation of 0.089. ?? 1982. |
