Mukhopadhyay B.; Walther J.V. (2001)Surface acidity of albite has been determined by potentiometric titration of water-washed and unwashed powders at 23.5°C and pH range of 2-9.5. Using NH4Cl as the background electrolyte the surface was titrated with HCl ...

Walther J.V. (1997)Based on a standard state of unit activity of the solute in a hypothetical one molal solution where activity coefficients are taken as unity at infinite dilution at all pressures and temperatures, the activity coefficients ...

Walther J.V. (2001)Corundum, α-Al2O3, solubility was measured in 0.1 and 0.5 m NaCl solutions from 400 to 600°C between 0.5 and 2.0 kbar. The base-10 logarithm of Al molality at 2 kbar in 0.5 m NaCl increases from -2.45 at 400°C to -1.52 at ...

Walther J.V. (2002)Corundum (α-Al2O3) solubility was measured in 0.1-molal CaCl2 solutions from 400 to 600°C between 0.6 and 2.0 kbar. The Al molality at 2 kbar increases from 3.1 x 10-4 at 400°C to 12.7 x 10-4 at 600°C. At 1 kbar, the ...

Walther J.V. (1997)Corundum solubility was measured in H2O between 350° and 600°C from 0.5 to 2.2 kbar. The base-10 logarithm of molality of Al in equilibrium with corundum along the 0.5 kbar isobar decreases with increasing temperature from ...
