Kalsyòm Phosphate Monobasic

Bone meal method first yellow phosphorus in the melting phosphorus tank melted into liquid, through the nozzle into the combustion hydration tower, while the compressed air will be phosphorus atomization, so that phosphorus oxidation and combustion to generate phosphorus pentoxide. At the top of the tower along the tower wall sprinkled 30 - 40 degree cycle of phosphoric acid, so that the phosphorus pentoxide gas cooling, while reacting with water to synthesize phosphoric acid. With the calcined and crushed bone powder according to CaO: P2O5=1 mixing reaction, to be ripe, coarse crushing, drying, crushing, the production of calcium dihydrogen phosphate. CaHPO42H2O+H3PO4→Ca(H2PO4)2H2O+H2O such as the ripened material will be leached with water, and the leaching solution will be filtered, evaporated, cooled and crystallized, dried, and then pure calcium phosphate finished product will be produced. Calcium hydroxide method 2 mol of phosphoric acid and 1 mol of calcium hydroxide for the reaction, control Ph3.2 or so, the generation of calcium dihydrogen phosphate. Filtering, evaporation, cooling, crystallization, centrifugal separation, washing with acetone, air-drying, calcium dihydrogen phosphate products. Ca(OH)2+2H3PO4→Ca(H2PO4)2H2O+H2O
