Phosphoric Acid, 85% Thermal Select NF / EP Grade

Phosphoric Acid, 85% Thermal Select  NF / EP Grade is the FCC Grade of Phosphoric Acid, 85% manufactured by a single step process of burning elemental phosphorus (P4) in air and reacting resultant oxide (P2O5) with water. The acid is then treated and filtered to further reduce metal levels. The P4 is produced by distillation from an electric arc furnace. Neither additional acids nor organic solvents are used in these processes.
