Study on lithium dihydrogen phosphate crystal growth conditions in nonstoichiometric solutions
Based on analysis of lithium dihydrogen phosphate (LDP) solubility dependence on solution stoichiometry alteration, solvent evaporation rate impact on solution supersaturation change is evaluated. It is revealed that at constant crystal growth rate relative solution supersaturation linearly depends...

It is revealed that at constant crystal growth rate relative solution supersaturation linearly depends on water evaporation rate. LDP nonstoichiometric saturated solution (20 % H₃PO₄ excess) stability boundary conditions are determined. Water evaporation rate is 0.5 %/24 h and supersaturation σ is 0.6 %/24 h, respectively. LDP nonstoichiometric solutions density and viscosity are measured. |
