Zotayidwa Boride ufa, AlB2

Aluminium boride (AlB2) ndi mtundu wamagulu ophatikizika opangidwa ndi aluminium ndi boron.

Ndi chofiyira chofiirira chofiirira pansi pa kutentha kwanthawi zonse komanso kukakamizidwa. Ndi khola asidi ozizira kuchepetsedwa, ndipo kuwonongeka mu asidi otentha hydrochloric ndi asidi nitric. Ndi imodzi mwamagawo awiri a aluminium ndi boron.

Aluminium borate (AlB2) ndi mtundu wamagulu ophatikizika opangidwa ndi aluminium ndi boron. Ndi imvi yofiirira yolimba pansi pazizolowezi kutentha komanso kuthamanga. Ndi khola asidi ozizira kuchepetsedwa, ndipo kuwonongeka mu otentha hydrochloric acid ndi nitric acid. Ndi imodzi mwamagawo awiri a aluminium ndi boron. Yina ndi alb12, yomwe nthawi zambiri imatchedwa aluminium borate. Alb12 ndi kristalo wonyezimira wakuda wonyezimira wokhala ndi mphamvu yayikulu ya 2.55 (18 ℃).

Imasungunuka m'madzi, acid ndi alkali. Imavunda mu nitric acid yotentha ndipo imapezeka ndi kusungunuka kwa boron trioxide, sulfure ndi aluminium limodzi.

Mapangidwe ake, ma atomu a B amapanga ma graphite okhala ndi ma atomu a Al pakati pawo, omwe amafanana kwambiri ndi kapangidwe ka magnesium diboride. Kristalo imodzi ya AlB2 imawonetsa mayendedwe azitsulo m'mbali molumikizana ndi ndege ya hexagonal ya gawo lapansi. Mitundu ya Boron aluminium imalimbikitsidwa ndi boron fiber kapena boron fiber yokhala ndi zokutira zoteteza.

Zomwe zili mu boron fiber zili pafupifupi 45% ~ 55%. Mphamvu yokoka yochepa, mawonekedwe apamwamba. Kutalika kwazitali zamphamvu komanso zotanuka za unidirectional zolimbitsa boron aluminium gulu ndi pafupifupi 1.2 ~ 1.7gpa ndi 200 ~ 240gpa, motsatana.

Kutalika kwazitali modulus modulus ndi mphamvu yapadera ndi pafupifupi 3 ~ kasanu ndi 3 ~ 4 ya titaniyamu aloyi duralumin ndi aloyi chitsulo, motsatana. Amagwiritsidwanso ntchito m'makina opanga ma turbojet, magalimoto othamangitsa komanso ma satellite. Njira yotentha yolimbirana yolumikizira imagwiritsidwa ntchito popanga mbale, mbiri ndi magawo okhala ndi mawonekedwe ovuta, ndipo njira yoponyera mosalekeza itha kugwiritsidwanso ntchito kupanga mbiri zosiyanasiyana.
