At Fang Chemicals Inc., we specialize in the marketing and distribution of phosphoric acid, phosphorous acid, and other phosphorous chemicals since 1987.
Thermal Phosphoric Acid
Phosphoric acid, also known as orthophosphoric acid, is a mineral acid with the chemical formula H3PO4. Pure, anhydrous phosphoric acid is a white solid which melts at 42 degrees Celsius to form a viscous liquid. Commonly used phosphoric acid is an aqueous solution of 75-85% H3PO4 which is generally produced by two different processes: wet process and thermal process.
Thermal process phosphoric acid is obtained by burning elemental phosphorus (P4) to produce phosphorus pent-oxide (P2O5) which is further dissolved in dilute phosphoric acid to make 75% or 85% product. This process produces a highly pure acid by removing most of the impurities present in the phosphate rock in an electric furnace where phosphorus (P) is released as a vapor. The arsenic (As) impurity can be further precipitated from phosphoric acid and reduced to less than 1 ppm.
There is need for thermal phosphoric acid in the U.S. market as a food and beverage additive, for water treatment, in metal finishing chemicals, and other areas. As a result, Fang Chemicals has established a domestic liquid bulk terminal (2,000 MT 85% phosphoric acid) to bring thermal phosphoric acid 85% from China as well as the ability to offer it at 75% or any lower concentration.
