3, nwere ike dochie silicon ígwè mpempe akwụkwọ, karịa 50% ike ịzọpụta.

4, nwere ngwa ụfọdụ na ụlọ ọrụ nuklia, rọketi nozzles, oke okpomọkụ, tube nchebe thermoelectric, akụkụ akpaaka na nrụpụta ndị ọzọ.

Aluminom borate (AlB2) bụ ụdị ọnụọgụ abụọ nke aluminom na boron kpụrụ.

Ọ bụ ihe siri ike na-acha ntụ ntụ n'okpuru ọnọdụ okpomọkụ na nrụgide nkịtị. Ọ kwụsiri ike na itughari oyi

acid, ma mebie ya na hydrochloric acid na nitric acid. Ọ bụ otu n'ime ha abụọ

ngwakọta nke aluminom na boron. Nke ọzọ bụ alb12, nke a na-akpọkarị aluminom

borate. Alb12 bụ kristal monoclinic ojii nwere nnukwu ike ndọda nke 2.55 (18 ℃).

Ọ na-esighi ike na mmiri, acid na alkali. Ọ na-emebi na nitric acid na-ekpo ọkụ wee nweta ya

site na agbaze boron trioxide, sọlfọ na aluminom ọnụ.

Na nhazi, atom B na-etolite flakes graphite na Al atom n'etiti ha, nke dị oke

yiri nhazi nke magnesium diboride. Otu kristal nke AlB2 na-egosi ọla

conductivity tinyere axis yiri ụgbọelu hexagonal nke mkpụrụ. Boron

A na-eme ka ihe mejupụtara aluminom sie ike site na eriri boron ma ọ bụ eriri boron nwere mkpuchi nchebe.

Olu ọdịnaya nke boron fiber bụ ihe dịka 45% ~ 55%. Nnukwu ike ndọda dị ala, dị elu

n'ibu Njirimara. Ike tensile ogologo na ngbanwe modul nke unidirectional

Ihe mejupụtara boron aluminom mesiri ike bụ ihe dịka 1.2 ~ 1.7gpa na 200 ~ 240gpa, n'otu n'otu.

The longitudinal kpọmkwem mgbanwe modulus na kpọmkwem ike bụ banyere 3 ~ 5 ugboro na

3 ~ 4 ugboro titanium alloy duralumin na alloy ígwè, n'otu n'otu. Ejila ya mee ihe

turbojet engine fan blades, ugbo ala ikuku na ihe owuwu satịlaịtị. Na ịpị ọkụ

A na-eji usoro njikọta mgbasa ozi arụpụta efere, profaịlụ na akụkụ nwere mgbagwoju anya
