Phosphoric Acid 75% is made two different ways:
-The wet process;
Phosphoric Acid 75% is produced from fluorapatite, a phosphate rock, and the addition of a concentrated acid, such as sulfuric acid, in a series of well-stirred reactors.
This results in Phosphoric Acid 75% and calcium sulfate (gypsum).
Water is added and the gypsum is removed by filtration along with other insoluble materials (e.g. silica).
Fluoride is removed at a further stage through evaporation.
-The thermal process;
The raw materials for this process are phosphorus and air.
Phosphorus is sprayed into a furnace and is burnt in air (dried or undried) at about 1800-3000 degrees Kelvin.
