Description

Solubility of salts in reciprocal system NH4Cl-NaVO3-NH4VO3-NaCl-H2O at 20 deg C was studied by the method of isothermal saturation using the chemical and X-ray phase analyses, the system solubility diagram being plotted. The diagram contains separate fields of salts crystallization, limited by five branches, and two ternary points. The ratio of the salts crystallization surface areas is approximately equal to 90000:10000:3:1 (NH4VO3:NaVO3:NaCl:NH4Cl), i.e. above 90% of crystallization field is occupied by ammonium vanadate, featuring the lowest solubility

Abstract (Russian)

Методом изотермического насыщения с использованием химического и рентгенофазового анализов исследована растворимость солей во взаимной системе NH4Cl-NaVO3-NH4VO3-NaCl-H2O при 20 град. С и построена ее диаграмма растворимости. На этой диаграмме присутствуют отдельные поля кристаллизации солей, разграниченные пятью ветвями, и две тройные точки. Соотношение площадей поверхности кристаллизации солей приблизительно равно 90000:10000:3:1 (NH4VO3:NaVO3:NaCl:NH4Cl), т.е. свыше 90% поля кристаллизации занимает ванадат аммония, который характеризуется самой низкой растворимостью
