Isticmaal:
Isticmaalka beeraha:Waxyaabaha ceeriin ee bacriminta fosfatetada iyo quudinta nafaqooyinka
Isticmaalka warshadaha: alaabta ceeriin kiimikaad
1.Birta ka ilaali daxalka
2. Isku darka nitric acid sida wakiilka polishing kiimikada si loo hagaajiyo dhamaadka dusha birta
3.Waxyaabaha phosphatide ee loo isticmaalo soo saarista alaabta lagu dhaqo iyo cayayaanka
4.Wax soo saarka fosfooraska ka kooban walxaha flameretardant.
Cuntooyinka lagu daro waxay isticmaalaan: dhadhanka aysidhka, Nafaqada khamiirka,, sida kookaha.
Isticmaalka caafimaad: si loo soo saaro dawo ka kooban fosfooraska, sida Na 2 Glycerophosphat
Ka dib markii la helay fosfooraska iyo farmashiyaha Jarmalka Conquer si uu u soo saaro fosfooraska, farmashiyaha Britishka ee Bo Yili ayaa sidoo kale si madax banaan u soo saaray fosfooraska. Waxa uu sidoo kale ahaa farmashiyihii ugu horreeyay ee bartay fosfooraska iyo isku-dhafka. Tijaabada cusub ee iftiinka qabow ee la arkay ayaa qoray "Phosphorus wuxuu abuuraa qiiq cad ka dib gubashada, iyo xalka la abuuray ka dib ficilka qiiqa cad iyo biyaha waa acidic." ), Xalka ka dhasha biyahana waa fosfooraska, laakiin ma uusan sii baran fosfatka.
Farmashiyihii ugu horreeyay ee bartay fosfatista wuxuu ahaa farmashiistaha Faransiiska Lawar. Sannadkii 1772-kii, waxa uu sameeyay tijaabadan oo kale: Ku rid fosfooraska daboolka gambaleelka meerkuri-shaabaysan si uu u gubo. Natiijooyinka tijaabada ah ayaa lagu soo gabagabeeyay in qadar gaar ah oo fosfooraska ah lagu gubi karo hawo awood leh; Qaybaha budada cad ee fosfooraska bilaashka ah ayaa la abuuraa marka fosfooraska gubto, sida baraf fiican; 80%; fosfooraska waa qiyaastii 2.5 jeer kahor gubashada; budada cad waxay ku milmay biyaha si ay u sameeyaan fosfooraska. Lavis waxa kale oo uu caddeeyey in fosfooraska lagu samayn karo nitric acid iyo fosfooraska.
In ka badan 100 sano ka dib, farmashiyaha Jarmalka Libii waxa uu sameeyay tijaabooyin kiimikaad badan oo beeraha ah si uu daaha uga qaado qiimaha fosfooraska iyo fosfattu ay u leeyihiin nolosha dhirta. Sannadkii 1840-kii, Li Bixi's "Doorka kiimikada organic ee beeraha iyo physiology" si cilmi ah u muujiyay dhibaatada bacriminta ciidda iyo tilmaamay doorka fosfooraska ee dhirta. Isla markaana waxa uu si qoto dheer u baadhayey isticmaalka phosphate iyo phosphate sida bacriminta, wax-soo-saarka fosfattu waxa uu galay xilli aad u balaadhan.
