Abstract: | The Me
2O-P2O5-H2O solubility phase diagrams are used to determine the optimum compositions and the temperatures for growing crystals of MeH2PO4 solid phases (Me = Li, Na, K, Rb, Cs, NH4). The optimum conditions for dynamic growth of dihydrophosphates of the elements of the first group and ammonium are determined.
LiH2PO4, NaH2PO4, NaH2PO4 · 2H2O, NaH2PO4 · H2O, KH2PO4, K(H,D)2PO4, RbH2PO4, CsH2PO4, and (NH4)H2PO4 single crystals are grown on seed from aqueous solutions by the methods of temperature lowering and isothermal evaporation.
