The main dependencies of aluminum phosphate solubility in
acid solutions at pressures from 4 up to 10 MPa and temperatures from
423 K up to 543 K have been presented. The optimum solvent for single-crystal
aluminum phosphate is the solution containing 85% H2SO4
and 15% HCl concentrations of both acids being 7.68 M. High
values solubility are obtained for pressures of 10 MPa. Our researches
are useful for determining the physical conditions that are essential
for the formation of aluminum phosphate single crystals in lab conditions.
