Amfanin phosporic acid:
Ana iya amfani da matakin fasaha na Phosphoric Acid don samar da nau'ikan Phosphates, ruwan magani na electrolyte ko ruwan magani na sinadarai, turmi mai jujjuyawa tare da acid phosphoric da inorganic coheretant. A shafi masana'antu phosphoric acid da ake amfani da a matsayin tsatsa-hujja shafi ga karafa; A matsayin mai sarrafa acidity da wakili mai gina jiki don ƙimar abinci yisti phosphoric acid za a iya amfani da shi ga dandano, abincin gwangwani da abin sha mai haske kamar yadda ake amfani da shi a cikin giya a matsayin tushen abinci mai gina jiki don yisti don hana haifuwa na ƙwayoyin cuta marasa amfani.

Ana amfani da sinadarin Phosphoric a cikin cire ƙura daga saman ƙarfen da ake amfani da shi azaman mai canza tsatsa ta hanyar kawo shi cikin hulɗa kai tsaye tare da ruɓaɓɓen ƙarfe, ko kayan aikin ƙarfe da sauran abubuwan da suka lalace. Yana taimakawa wajen tsaftace ma'adinan ma'adinai, siminti nous smears da tabon ruwa. Ana amfani dashi don acidify abinci da abubuwan sha kamar colas. Phosphoric acid wani abu ne mai mahimmanci a cikin magunguna masu yawa don magance tashin zuciya. Phosphoric acid yana haɗe da foda na zinc kuma yana samar da zinc phosphate, kuma yana da amfani a siminti na ɗan lokaci. A cikin orthodontics, ana amfani da zinc a matsayin maganin etching don taimakawa tsaftacewa da ɓata saman hakora.
