Ingcaciso yeMveliso

 I-1, Isetyenziswe njengesixhobo se-semiconductor kwi-rectifier yokushisa okuphezulu, i-doped material, imathiriyeli ye-tube, izinto ze-cathode kunye nobushushu obuphezulu be-nyutroni ye-reactor neutron efunxayo.

I-2, le alloy ekhethekileyo inokumelana nokunxiba kakuhle, ukumelana nobushushu, ukuxhathisa kwe-oxidation, ukuxhathisa kunye nobushushu kunobudlelwane bomgca.Ingasetyenziselwa i-ceramic yensimbi, i-coat-resistant coating, ukumelana nobushushu obuphezulu, i-crucible lining, ukuzaliswa kunye ne-anti-corrosion. izixhobo zekhemikhali zokutshiza.Isenokusetyenziswa njengezinto ezingaphiliyo ezinzima kakhulu.

3, inokutshintsha i-silicon sheet yentsimbi, ngaphezulu kwe-50% yokonga amandla.

4, ube nesicelo esithile kushishino lwenyukliya, imilomo yerokethi, iibheringi zobushushu obuphezulu, ityhubhu yokukhusela i-thermoelectric, iinxalenye zemoto kunye nokunye ukuvelisa.

I-aluminium borate (i-AlB2) luhlobo lwe-binary compound eyenziwe yi-aluminiyam kunye ne-boron.

Iqinile ebomvu engwevu phantsi kobushushu obuqhelekileyo kunye noxinzelelo.Izinzile kwi-dilute ebandayo

iasidi, kwaye ibolile kwi-asidi ye-hydrochloric eshushu kunye ne-nitric acid.Yenye yezi zimbini

iikhompawundi ze-aluminiyam kunye ne-boron.Enye yi-alb12, edla ngokubizwa ngokuba yi-aluminiyam

iborate.I-Alb12 yikristale emnyama ekhazimlayo ye-monoclinic enobunzima obuthile obuyi-2.55 (18 ℃).

Ayinyibiliki emanzini, iasidi kunye nealkali.Ibola kwi-nitric acid eshushu kwaye ifunyenwe

ngokunyibilikisa i-boron trioxide, isulfure kunye ne-aluminiyam kunye.

Kwisakhiwo, ii-athomu ze-B zenza iiflekhi zegraphite ezine-athomu ze-Al phakathi kwazo, ezibaluleke kakhulu

efana nesakhiwo se-magnesium diboride.Ikristale enye ye-AlB2 ibonisa isinyithi

i-conductivity ecaleni kwe-axis ehambelana ne-hexagonal plane ye-substrate.Boron

Iimbumba ze-aluminium zomelezwa yi-boron fiber okanye i-boron fiber ene-coating yokukhusela.

Umxholo womthamo we-boron fiber malunga ne-45% ~ 55%.Umxhuzulane othile ophantsi, uphezulu

iimpawu zoomatshini.Amandla e-longitudinal tensile kunye ne-elastic modulus ye-unidirectional

i-boron aluminium composite eyomeleziweyo imalunga ne-1.2 ~ 1.7gpa kunye ne-200 ~ 240gpa, ngokulandelelanayo.

Longitudinal imodyuli elastiki ethile kunye namandla athile malunga 3 ~ 5 amaxesha kunye

I-3 ~ 4 amaxesha e-titanium alloy duralumin kunye nentsimbi ye-alloy, ngokulandelanayo.Isetyenziswe kwi

i-turbojet fan fan blades, izithuthi ze-aerospace kunye nezakhiwo zesathelayithi.Ukucinezela okushushu

indlela yokudibanisa i-diffusion isetyenziselwa ukwenza iipleyiti, iiprofayili kunye neenxalenye ezinobunzima

iimilo, kunye nendlela yokuphosa eqhubekayo ingasetyenziselwa ukwenza iiprofayili ezahlukeneyo.
