N'ịgbaso nchọpụta nke phosphorus na German chemist Conquer na-emepụta phosphorus, British chemist Bo Yili nyekwara onwe ya mepụta phosphorus. Ọ bụkwa onye mbụ chemist gụrụ phosphorus na compound.

Onye mbụ chemist gụrụ phosphate bụ onye France chemist Lawar. N'afọ 1772, o mere nnwale dị otú ahụ: Tinye phosphorus n'ime mkpuchi mgbịrịgba mercury-mechiri emechi iji gbaa ya ọkụ.

Mgbe ihe karịrị otu narị afọ gachara, onye German chemist Libii emeela ọtụtụ nnwale kemịkalụ ugbo iji kpughee uru phosphorus na phosphate bara na ndụ osisi.
