Hlau boride yog ib qho ionic compound, nrog hexagonal siv lead ua qauv. Hlau boride 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.

Boron Iron hmoov yog siv hauv cov hlau thiab cam khwb cia hlau. Nws tuaj yeem siv rau hauv cov qauv hlau alloy steel, caij nplooj ntoos hlav steel, siab zog qis alloy steel, kub resistant steel, stainless hlau thiab lwm yam. Boron Iron tuaj yeem txhim kho toughness, hnav tsis kam hauv cam khwb cia hlau. Nws kuj yog siv dav hauv kev tsim tsheb, tsheb laij teb thiab tshuab cuab yeej thiab lwm yam.
