Ibhismuth

I-Bismuth ibonakaliswe kwitheyibhile yeperiodic kunye nesimboli u-Bi, inombolo yeathomu engama-83, kunye nobunzima beathom obungama-208.98. I-Bismuth i-brittle, crystalline, intsimbi emhlophe kunye ne-pink tinge encinci. Ineendlela ezahlukeneyo zokusetyenziswa, kubandakanywa izinto zokuthambisa, iialloys, izicima-mlilo kunye neembumbulu. Mhlawumbi yaziwa kakhulu njengeyona nto iphambili kunyango lwesisu esifana nePepto-Bismol.

I-Bismuth, i-element 83 kwi-periodic table yezinto, yintsimbi yasemva kwenguqu, ngokutsho kweLos Alamos National Laboratory. (Iinguqulelo ezahlukeneyo zetafile yeperiodic ziyimela njengentsimbi yenguqu.) Iintsimbi zenguqu - iqela elikhulu lezinto, ezibandakanya ubhedu, i-lead, isinyithi, i-zinc kunye negolide - zinzima kakhulu, zineendawo eziphezulu zokunyibilika kunye namanqaku abilayo. Iintsimbi zasemva kwenguqu zabelana ngeempawu ezithile zetsimbi yotshintsho kodwa zithambile kwaye ziqhuba kakubi kakhulu. Enyanisweni, i-bismuth yombane kunye ne-thermal conductivity iphantsi ngokungaqhelekanga kwintsimbi. Ikwanendawo yokunyibilika esezantsi kakhulu, nto leyo eyenza ukuba yenze ingxubevange enokusetyenziselwa ukubumba, izixhobo zokujonga umlilo kunye nezinto zokucima umlilo.

Isinyithi seBismuth sisetyenziswa ekwenzeni ii-solder ezinyibilikayo ezisezantsi kunye neealloys ezixubeneyo kunye netyhefu ephantsi yokudutyulwa kweentaka kunye nezitsiki zokuloba. Ezinye iikhompawundi zebismuth ziyenziwa kwaye zisetyenziswe njengamayeza. Umzi-mveliso usebenzisa iikhompawundi ze-bismuth njengezinto ezinceda ekwenzeni i-acrylonitrile, imathiriyeli yokuqala yeentsinga zokwenziwa kunye neerabha. I-Bismuth ngamanye amaxesha isetyenziselwa ukuveliswa kweembumbulu kunye nemipu.
