Triple superphosphate
Triple superphosphate is a component of fertilizer that primarily consists of monocalcium phosphate, Ca(H2PO4)2. Triple superphosphate is obtained by treating phosphate rock with phosphoric acid. Traditional routes for extraction of phosphate rock uses sulfuric acid gives single superphosphate, an approximate 1:1 mixture of Ca(H2PO4)2 and CaSO4 gypsum). That mixture is called single superphosphate. Many fertilizers are derived from triple superphosphate, e.g. by blending with ammonium sulfate and potassium chloride. Double superphosphate refers to some average of triple- and single superphosphate, resulting from the extraction of phosphate rock with aa mixture of phosphoric and sulfuric acids.[1]
