Aluminium Diboride Alb2 Hmoov

 1, siv ua cov khoom siv kub semiconduction rau cov khoom kub kub, cov khoom siv raj, cov raj khoom siv raj, cov khoom siv raj ntawm cov khoom siv raj, cov khoom siv raj ntawm cov khoom siv raj, hluav taws xob nuclear neutroning cov khoom.

2, qhov tshwj xeeb no muaj qhov hnav tsis zoo, kub tsis kam, ua kom sov, txhaws tau cov khoom tawg thiab tiv thaiv corrosion corrosion. Nws kuj tseem siv tau ua cov khoom siv hluav taws xob super-nyuaj inorganic.

3, tuaj yeem hloov cov ntawv silicon steel, ntau dua 50% txuag hluav taws xob.

4, muaj qee qhov kev thov nyob rau hauv kev lag luam nuclear, foob pob hluav taws, cov kabmob kub, lub thermoelectric kev tiv thaiv lub raj, teeb pib thiab lwm yam kev tsim khoom.

Aluminium borate (Alb2) yog ib hom binary compound tsim los ntawm aluminium thiab boron.

Nws yog xim grey kom ruaj khov nyob rau hauv qhov kub thiab kub. Nws yog ruaj khov nyob rau hauv txias dilute

Acid, thiab decomposed nyob rau hauv kub hydrochloric acid thiab nitric acid. Nws yog ib qho ntawm ob

tebchaw ntawm txhuas thiab boron. Lwm tus yog alb12, uas feem ntau hu aluminium

borate. Alb12 yog dub lwrot monoclinic siv lead ua nrog lub ntiajteb txawj nqus tshwj xeeb ntawm 2.55 (18 ℃).

Nws yog insoluble hauv dej, kua qaub thiab alkali. Nws decomposes nyob rau hauv kub nitric acid thiab yog tau

Los ntawm melting boron trioxide, leej faj thiab aluminium ua ke.

Hauv cov qauv, b Atoms daim ntawv graphite flakes nrog aloms nruab nrab ntawm lawv, uas yog heev

Zoo ib yam li cov qauv ntawm cov magnesium diborium. Tib lub lead ntawm alb2 qhia hlau

Conductivity raws lub axis mus sib xws rau lub hexagonal dav hlau ntawm substrate. Boron

Aluminium composites yog txhawb nqa los ntawm boron fiber ntau lossis boron fiber nrog kev tiv thaiv kev tiv thaiv.

Cov ntsiab lus ntsiab lus ntawm boron fiber muaj txog 45% ~ 55%. Tsawg tshaj cov ntiajteb txawj nqus, siab

cov khoom siv neeg kho tshuab. Lub zog ntev tensiles lub zog thiab elastic modulus ntawm unidirectional

Txhim kho Boron Aluminium sib haum yog txog 1.2 ~ 1.7GPA thiab 200 ~ 240gpa, ntsig txog.

Lub longitudinal tshwj xeeb elastic modulus thiab lub zog tshwj xeeb yog li 3 ~ 5 zaug thiab

3 ~ 4 zaug ntawm titanium alloy duralumin thiab alloy steel, ntsig txog. Nws tau siv nyob rau hauv

Turbajet lub tshuab kiv cua npog, AEROSPACACE tsheb thiab SATELLILite qauv. Cov Kub Kub

diffusion lawb txheej txheem yog siv los tsim cov phiaj hlau, profiles thiab qhov chaw nrog cov nyom

Cov duab, thiab txuas ntxiv castting txoj kev kuj tseem siv tau los tsim cov khoom siv ntau yam.
