Methods and apparatus for reacting ammonia and phosphoric acid in a high temperature vaporous reaction. The apparatus includes a tee mixer wherein hot ammonia is used to heat and atomize phosphoric acid, and a loop reactor wherein the mixed reactants are retained for from 0.10 to 0.18 seconds after which the reaction product is immediately quenched. The apparatus also includes materials handling devices for controlling reactant flows and reaction conditions whereby high analysis polyphosphate fertilizers are produced in dry or liquid form.
