摘要：
Solubility in the potassium sulfate-ammonium sulfate-water system is investigated. Two inflexions are distinctly seen in the Janecke equilibrium lines, one at similar to 90 mol % NH(4) in the solution line and the other at similar to 10 mol % NH(4) in the precipitate line. A thorough X-ray powder diffraction study of (K,NH(4))(2)SO(4) crystals was made to detect probable structural transformations. The existence of the stoichiometric (K,NH(4))(2)SO(4) phase is suggested.
