Boride birtu waa iskudhis ionic ah, oo leh qaab dhismeed kristal ah. Boride-ka birta ee heerkulku waxyar 40K (oo u dhiganta -233 ℃) waxa 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 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 beerta magnetic, ama ay jirto gudubka hadda, awoodda lagu ilaalinayo waxqabadka sare waa sida ugu badan ee niobium alloys, ama xitaa ka sii fiican.

Budada Ironta waxaa inta badan loo isticmaalaa birta iyo birta. Waxaa loo isticmaali karaa birta daawaha qaab dhismeedka, birta guga, birta daawaha hoose ee xoogga sare leh, birta kulaylka u adkeysata, birta aan lahayn iwm. Waxa kale oo si weyn loogu isticmaalaa samaynta baabuurta, cagafyada iyo qalabka mashiinka iwm.
