WebPhosphoric acid is usually manufactured or prepared using two different types of processes. These processes are the wet process and the thermal process. Wet Process During the wet process of preparing phosphoric acid, it is produced from a naturally occurring crystal rock fluorapatite. Fluorapatite contains the phosphate mineral within it. WebThe basic compounds for the production of polyphosphoric acid (PPA) are phosphorus pentoxide (P2O5) and phosphoric acid (H3PO4), as shown in Figure 2. Phosphorus is first oxidized to phosphorus pentoxide, which crystallizes as P4O10. Upon its reaction with water, phosphoric acid is produced. This route to H3PO4 is known as the dry process,
