Chromium boride hmoov Daim ntawv thov:
Chromium diboride yog ib qho ionic compound, nrog hexagonal siv lead ua qauv. Chromium diboride ntawm qhov kub thiab txias me ntsis 40K (sib npaug rau -233 ℃) yuav hloov mus rau hauv superconductor.
Thiab nws qhov tseeb ua haujlwm kub yog 20 ~ 30K. Txhawm rau kom ncav cuag qhov ntsuas kub no, peb tuaj yeem siv cov kua neon, kua hydrogen lossis kaw lub voj voog lub tub yees kom ua tiav qhov txias.
Piv rau kev lag luam tam sim no siv cov kua helium kom txias cov niobium alloy (4K), cov txheej txheem no yooj yim dua thiab pheej yig dua. Thaum nws yog doped nrog carbon los yog lwm yam impurities, magnesium diboride nyob rau hauv ib tug sib nqus teb, los yog muaj ib tug tam sim no dhau mus, lub peev xwm los tuav lub superconducting yog ntau npaum li niobium alloys, los yog txawm zoo dua.
