【摘要】 用Na₂SnF₆为初始物质,研究该络合物在200—602℃、1kbar的水热溶液中的水解特征。实验表明,Na₂SnF₆发生强烈酸性水解,随温度升高水解作用加强,400℃左右曲线由陡变缓。水解受酸度影响较大。该实验条件下,求得锡在水热溶液中最可能的存在形式为SnF₃（OH）或Na₂SnF₃（OH）。此外还计算了Na₂SnF₆的水解常数与温度变化的关系。更多还原

【Abstract】 Characteristics of hydrolysis of the complex Na2SnF6, which is used as the starting material, in hydrothermal solutions have been studied at 200-602° and 1 kbars. Ex-perimental 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 hydro-thermal solutions is SnF3(OH) or Na2SnFs(OH). In addition, the hydrolysis constants for Na2SnF6 have also been calculated from 200° to 602℃, and the relationship between Na2SnF6 hydrolysis and temperature is discussed.更多还原
