The influence of urea on the K2CO3 and NH4VO3 solubility in the K2CO3 + NH4VO3 + H2O system The influence of urea on the vanadium(V) and potassium ion concentrations in the K2CO3 + NH4VO3 + H2O system was determined in the temperature range of 293 K to 313 K. Additionally, the solution density dependence versus the urea concentration was presented. These data are essential for the assessment of optimum operating conditions for the new production process of potassium carbonate.
