Abstract

Some factors affecting the stability of KH₂РО₄ aqueous solutions have been investigated. The width of the metastable zone of KH₂РО₄ solutions saturated at a temperature of 65–80°C is estimated. The solubility curves of the solutions with pH values of 2.5 and 5.4 are analyzed, and the influence of pH on the stability of KH₂РО₄ solutions in growth crystallizers is investigated for the first time.
