    Cia

    Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhov cua, qhuav thiab huv warehouse.

    Kev ruaj ntseg

    Nws yog qhov ruaj khov ntawm qhov kub thiab txias, thiab kub hnyiab hauv lub teeb xiav nplaim thaum sov, thiab ua rau daj lossis xim av bismuth oxide.

    Lub ntim ntawm cov hlau molten nce tom qab condensed.

    Tsis txhob sib cuag nrog oxides, halogens, acids, thiab interhalogens.

    Nws yog insoluble hauv hydrochloric acid thaum tsis muaj cua, thiab nws tuaj yeem yaj maj mam thaum huab cua nkag mus rau hauv.

    Lub ntim nce los ntawm cov kua rau cov khoom, thiab qhov nthuav dav yog 3.3%.

    Nws yog nkig thiab yooj yim crushed, thiab tsis zoo hluav taws xob thiab thermal conductivity.

    Nws tuaj yeem cuam tshuam nrog bromine thiab iodine thaum rhuab.

    Nyob rau hauv chav tsev kub, bismuth tsis hnov ​​​​mob nrog oxygen lossis dej, thiab tuaj yeem hlawv kom tsim bismuth trioxide thaum rhuab saum lub melting point.

    Bismuth selenide thiab telluride muaj cov khoom siv semiconducting.
