Bismuth trioxide (Bi2O3) shine sinadarin oxide na kasuwanci da ake amfani da shi a cikin bismuth. Ana amfani da shi sosai a masana'antar yumbu da gilashi, roba, robobi, tawada, da fenti, likitanci da magunguna, kayan aikin nazari, Varistor, da na'urorin lantarki.
Ana amfani da Bismuth trioxide a matsayin wani abu da ya fara shirya wasu sinadarai na bismuth, don shirya gishirin bismuth da kuma ƙera takarda mai hana wuta a matsayin sinadaran nazarin sinadarai. Ana iya amfani da wannan bismuth oxide sosai a cikin haɗakar da ba ta da sinadarai, tukwane na lantarki, reagents na sinadarai, da sauransu, galibi ana amfani da shi don ƙera capacitors na yumbu dielectric kuma ana iya amfani da shi don ƙera abubuwan yumbu na lantarki kamar tukwane na piezoelectric da piezoresistors.
Bismuth Trioxide yana da amfani na musamman a gilashin gani, takarda mai hana harshen wuta, kuma, a mafi yawan lokuta, a cikin tsarin gilashi inda yake maye gurbin gubar oxides. A cikin shekaru goma da suka gabata, bismuth trioxide shi ma ya zama babban sinadari a cikin tsarin kwararar da masu nazarin ma'adanai ke amfani da shi a gwajin wuta.
