ʻO Bismuth trioxide (Bi2O3) ka oxide kūʻai maʻamau o ka bismuth. Hoʻohana nui ʻia ia i ka ʻoihana o Ceramics a me nā aniani, Rubbers, Plastics, Inks, and Paints, Medical and Pharmaceuticals, Analytical reagents, Varistor, Electronics.
Hoʻohana ʻia ʻo Bismuth trioxide no ka hoʻomākaukau ʻana i nā paʻakai bismuth a me ka hana ʻana i ka pepa ahi e like me nā reagents analytic kemika. Hiki ke hoʻohana nui ʻia kēia bismuth oxide i ka inorganic synthesis, electronic ceramics, chemical reagents, etc., i hoʻohana nui ʻia no ka hana ʻana i nā capacitors ceramic dielectric a hiki ke hoʻohana ʻia no ka hana ʻana i nā mea seramika uila e like me ka piezoelectric ceramics a me nā piezoresistors.
Ua hoʻohana kūikawā ʻo Bismuth Trioxide i ke aniani aniani, ka pepa pale ahi, a me ka hoʻonui nui ʻana, i loko o nā hana aniani kahi e pani ai i nā oxides kepau. I nā makahiki he ʻumi i hala iho nei, ua lilo ʻo bismuth trioxide i mea koʻikoʻi i nā hoʻoheheʻe flux i hoʻohana ʻia e nā mea loiloi mineral i ka hoʻāʻo ʻana i ke ahi.
