Bismuth CAS 7440-69-9
Hiki i ka Bismuth ke hoʻā iā ia iho i loko o ke kinoea chlorine a hui pū me ka bromine, iodine, sulfur, a me selenium e hana i nā pūhui trivalent ke hoʻomehana ʻia. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka waika hydrochloric dilute a me ka waikawa sulfuric dilute, hiki ke hoʻoheheʻe ʻia i loko o ka waikawa nitric a me ka ʻakika sulfuric concentrated e hana i nā paʻakai bismuth trivalent. ʻO nā minerala nui ka bismuthinite a me ka bismuthinite. ʻO 2.0 × 10-5% ka nui o ka honua.

ʻO ka hoʻohana nui ʻana o ka bismuth ma ke ʻano he ʻāpana o nā mea hoʻoheheʻe haʻahaʻa (melting) no nā lako pale ahi, nā mea hoʻopili metala, a me nā media conductive thermal. Hoʻohana ʻia no ka hoʻomākaukau ʻana i nā lāʻau lapaʻau no ka mālama ʻana i nā maʻi ʻōpū a me nā syphilis. Hoʻohana ʻia no nā lako uila (thermoelectric alloys and permanent magnets). Hoʻohana ʻia ma ke ʻano he catalyst, ʻoi loa i ka hoʻomākaukau ʻana i ka acrylonitrile. ʻO nā seramika wela a me nā puaʻa, etc.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
