Bismuth trioxide (Bi2O3) bụ oxide azụmaahịa a na-ejikarị eme ihe na bismuth. A na-ejikarị ya eme ihe n'ọtụtụ ụlọ ọrụ dịka seramiiki na iko, rọba, plastik, inks, na agba, ọgwụ na ọgwụ, ihe nyocha, varistor, na eletrọniki.
Dịka ihe mbụ e ji kwadebe ihe ndị ọzọ e ji bismuth mee, a na-eji bismuth trioxide eme ihe maka ịkwadebe nnu bismuth ma na-emepụta akwụkwọ na-anaghị agba ọkụ dị ka ihe ndị na-eme ka ihe nyocha kemịkalụ ghara ịdị. Enwere ike itinye bismuth oxide a n'ọtụtụ ebe na mmepụta inorganic, seramiiki eletrọnịkị, ihe ndị na-eme kemịkalụ kemịkalụ, wdg., a na-ejikarị ya eme ihe maka imepụta ihe ndị na-eme ka seramiiki dielectric dị na seramiiki eletrọnịkị, a pụkwara iji ya mee ihe maka imepụta ihe seramiiki eletrọnịkị dịka seramiiki piezoelectric na piezoresistors.
