I-Phosphate ingenye yezithako zemvelo cishe zakho konke ukudla futhi isetshenziswa kakhulu ekucubunguleni ukudla njengesithako esibalulekile sokudla kanye nesithasiselo esisebenzayo. I-phosphate eyenzeka ngokwemvelo i-phosphate rock (equkethe i-calcium phosphate). I-Sulfuric acid ihlangana nedwala le-phosphate ukuze kukhiqizwe i-calcium dihydrogen phosphate ne-calcium sulfate engamuncwa izitshalo ukuze ikhiqize i-phosphate. Ama-phosphates angahlukaniswa abe ama-orthophosphates nama-polycondensed phosphates: ama-phosphates asetshenziswa ekucubunguleni ukudla ngokuvamile i-sodium, i-calcium, i-potassium, ne-iron kanye nosawoti we-zinc njengeziqinisi izakhi. Ama-phosphates ebanga lokudla asetshenziswa kakhulu Kunezinhlobo ezingaphezu kwama-30. I-sodium phosphate iwuhlobo olusetshenziswa kakhulu lwe-phosphate yokudla yasekhaya. Ngokuthuthuka kobuchwepheshe bokucubungula ukudla, ukusetshenziswa kwe-potassium phosphate nakho kuyanda unyaka nonyaka.
