Abstract

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.
