Codsiga budada chromium boride:
Chromium diboride waa iskudhis ionic ah, oo leh qaab dhismeed kristal ah. Chromium diboride oo heerkulkiisu yara dhan yahay 40K (oo u dhiganta -233 ℃) ayaa loo beddeli doonaa kondhondher sare.
Heerkulkeeda dhabta ah ee shaqayntu waa 20 ~ 30K. Si aan u gaarno heerkulkan, waxaan isticmaali karnaa neon dareere ah, hydrogen dareere ah ama qaboojiyaha wareegga xiran si aan u dhameyno qaboojinta.
Marka la barbardhigo warshadaha hadda jira ee isticmaalaya helium dareere ah si ay u qaboojiyaan niobium alloy (4K), hababkani waa kuwo fudud oo dhaqaale badan. Marka lagu daro kaarboon ama wasakh kale, magnesium diboride ee goobta magnetic, ama ay jirto gudubka hadda, awoodda lagu ilaalinayo waxqabadka sare waa sida ugu badan ee niobium alloys, ama xitaa ka sii fiican.
