Bismuth jẹ funfun fadaka si irin Pink, eyiti a lo ni akọkọ lati mura awọn ohun elo semikondokito, awọn agbo ogun bismuth mimọ-giga, awọn ohun elo firiji thermoelectric, awọn olutaja ati awọn gbigbe omi itutu agbaiye ni awọn reactors iparun, ect. Bismuth waye ni iseda bi irin ọfẹ ati nkan ti o wa ni erupe ile.
Ẹya ara ẹrọ
1.High-purity bismuth ti wa ni o kun lo ninu iparun ile ise, Aerospace ile ise, Electronics ile ise ati awọn miiran apa.
2.Since bismuth ni awọn ohun-ini semiconducting, resistance rẹ dinku pẹlu iwọn otutu ti o pọ si ni awọn iwọn kekere. Ni thermocooling ati thermoelectric iran agbara, Bi2Te3 ati Bi2Se3 alloys ati Bi-Sb-Te ternary alloys fa ifojusi julọ. In-Bi alloy ati Pb-Bi alloy jẹ awọn ohun elo ti o ga julọ.
3.Bismuth ni aaye yo kekere, iwuwo giga, titẹ agbara kekere, ati apakan agbekọja gbigbe neutroni kekere, eyiti o le ṣee lo ni awọn olutọpa atomiki giga-giga.
Ohun elo
1. O ti wa ni o kun lo lati mura yellow semikondokito ohun elo, thermoelectric refrigeration ohun elo, solders ati omi itutu ẹjẹ ni iparun reactors.
2.Lo fun ngbaradi semikondokito awọn ohun elo ti o ga-mimọ ati awọn agbo ogun bismuth ti o ga julọ. Ti a lo bi itutu ni awọn reactors atomiki.
3. O ti wa ni o kun lo ninu oogun, kekere yo ojuami alloy, fiusi, gilasi ati awọn ohun elo amọ, ati ki o jẹ tun kan ayase fun roba gbóògì.
