Abstract

The solubility of water in melts of albitic (Ab: NaAlSi3O8) and orthoclasic (Or: KAlSi3O8) compositions was re-investigated at T = 1100°C and at pressures between 0.5 and 5.0 kbar. The influence of starting materials, sample preparation, run procedure and analytical methods on the solubility data was investigated systematically. Different analytical techniques (Karl-Fischer titration (KFT), near-infrared spectroscopy (NIR), 105°C weight loss and weight loss on ignition) give consistent results under certain conditions, whereas water-specific methods (KFT and NIR) have a higher precision. -from Author
