Characteristics of hydrolysis of the complex Na2SnF6, which is used as the starting material, in hydrothermal solutions have been studied at 200-602??C and 1 kbar. Experimental results show that intense hydrolysis of Na2SnF6 occurs at high temperatures and that with the rise of temperature the hydrolysis will become more intense. Under the present experimental conditions the most possible existing form of Sn in the hydrothermal solutions is SnF3(OH) or Na2SnF3(OH). In addition, the hydrolysis constants for Na2SnF6 have also been calculated at 200-602??C, and the relationship between Na2SnF6 hydrolysis and temperature is discussed. ?? 1987 Science Press.
