 1, Imagwiritsidwa ntchito ngati semiconductor zinthu zowongolera kutentha kwambiri, zinthu zopindika, chubu, zida za cathode ndi zinthu zotengera za nyukiliya zanyukiliya.

2, alloy yapaderayi imakhala ndi kukana kwabwino, kukana kutentha, kukana kwa okosijeni, kukana ndi kutentha kumakhala ndi ubale wolumikizana. Itha kugwiritsidwa ntchito ngati zitsulo za ceramic, zokutira zosagwira ntchito, kukana kutentha, kuyika crucible, kudzaza ndi anti-corrosion. kupopera mankhwala mankhwala.Itha kugwiritsidwanso ntchito ngati zida zolimba kwambiri.

3, akhoza m'malo mwa chitsulo pepala pakachitsulo, kuposa 50% kupulumutsa mphamvu.

4, khalani ndi ntchito inayake pamakampani a nyukiliya, ma rocket nozzles, mayendedwe otentha kwambiri, chubu lachitetezo cha thermoelectric, zida zamagalimoto ndi zinthu zina.

Aluminiyamu borate (AlB2) ndi mtundu wa binary pawiri wopangidwa ndi aluminiyamu ndi boron.

Ndi imvi wofiira olimba pansi yachibadwa kutentha ndi kupanikizika.Ndi khola ozizira kuchepetsa

asidi, ndi kuwola mu otentha hydrochloric acid ndi asidi nitric.Ndi imodzi mwa ziwirizo

mankhwala a aluminium ndi boron.Lina ndi alb12, lomwe nthawi zambiri limatchedwa aluminium

borate.Alb12 ndi kristalo wakuda wonyezimira wa monoclinic wokhala ndi mphamvu yokoka ya 2.55 (18 ℃).

Sisungunuka m'madzi, asidi ndi alkali.Imawola mu asidi wotentha wa nitric ndipo imapezeka

posungunula boron trioxide, sulfure ndi aluminiyamu pamodzi.

Pamapangidwe, ma atomu a B amapanga ma graphite flakes ndi ma atomu a Al pakati pawo, omwe ali kwambiri

zofanana ndi kapangidwe ka magnesium diboride.Crystal imodzi ya AlB2 imawonetsa chitsulo

madutsidwe motsatira olamulira kufanana ndi hexagonal ndege ya gawo lapansi.Boroni

zitsulo za aluminiyamu zimalimbikitsidwa ndi ulusi wa boron kapena ulusi wa boron wokhala ndi zokutira zoteteza.

Kuchuluka kwa boron fiber ndi pafupifupi 45% ~ 55%.Mphamvu yokoka yotsika, yokwera

makina katundu.The longitudinal tensile mphamvu ndi zotanuka modulus wa unidirectional

Kuphatikizika kwa aluminiyamu ya boron kuli pafupifupi 1.2 ~ 1.7gpa ndi 200 ~ 240gpa, motsatana.

The longitudinal enieni zotanuka modulus ndi mphamvu yeniyeni ndi za 3 ~ 5 nthawi ndi

3 ~ 4 nthawi za titaniyamu aloyi duralumin ndi aloyi chitsulo, motero.Yagwiritsidwa ntchito mu

masamba a injini ya turbojet, magalimoto apamlengalenga ndi mawonekedwe a satellite.Kukanikiza kotentha

Diffusion bonding njira imagwiritsidwa ntchito popanga mbale, mbiri ndi magawo okhala ndi zovuta

mawonekedwe, ndi njira yosalekeza yoponyera ingagwiritsidwenso ntchito kupanga mbiri zosiyanasiyana.
