Mutual salts solubility in the NaVO3 + NH4HCO3 + NH4VO3 + NaHCO3 + H2O system at temperature 303 K and the carbonization degree (R) of 90% has been studied. On the basis of the compiled data, a solubility polytherm section in the oblique projection on plane according to Janecke has been plotted. It has been found out that ammonium metavanadate is a sparingly soluble salt, NH4VO3 and NaHCO3 compose the stable pair of salts, whereas the triple points P1, P2 are represented by solutions convergently saturated. A thorough knowledge of the solubility isotherm course for the reciprocal salt pairs system is essential for an elaboration of sodium carbonate production technology based on NaVO3 as an initial reactant.
