Hafnium ntụ ntụ
Nkọwa ngwaahịa
Hafnium ntụ ntụ bụ ọla ọcha na-acha ọcha, n'ihe gbasara ihe anụ ahụ, hafnium ntụ ntụ nwere ebe na-agbaze dị elu na ebe na-esi nri dị elu, ebe agbaze ya bụ 2545 ° C, ebe a na-esi nri bụ 3876 ° C. Ọ nwekwara nnukwu ikuku ọkụ. na elu resistivity, ya mere a na-ejikarị eme ihe n'ichepụta superalloys na electronic components.N'ihe gbasara akụrụngwa kemịkalụ, ntụ ntụ hafnium dị mfe iji ihe ndị na-abụghị ọla dị ka oxygen na nitrogen mepụta oxides na nitrides kwekọrọ.Ọ na-etolitekwa alloys nwere ọtụtụ ọla, dị ka alloys dabere na hafnium.N'ihe banyere ojiji na mkpa, hafnium ntụ ntụ bụ ihe dị oke mkpa, nke a na-ejikarị eme ihe na mbara igwe, agha, ngwá electronic na ubi ndị ọzọ.Dịka ọmụmaatụ, a na-ejikọta ya na tungsten, rhenium na ọla ndị ọzọ n'ime ike dị elu, na-ekpo ọkụ na-eguzogide hafnium alloys maka imepụta engines ụgbọ elu na igwe rọketi.Na mgbakwunye, hafnium ntụ ntụ nwekwara ike iji rụpụta ihe elektrọnik, dị ka capacitors, resistors, wdg.

Hafnium Hf ntụ ntụ bụ nke ejiri maka:
1. A na-ejikarị X-ray cathode na tungsten waya n'ichepụta;
2. Hafnium dị ọcha nwere uru nke plasticity, nhazi dị mfe na nguzogide corrosion okpomọkụ dị elu, ma bụrụ ihe dị mkpa na ụlọ ọrụ ike atomiki;
3. Hafnium nwere nnukwu ihe na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ, na-eme ka ọ bụrụ ihe na-ekpo ọkụ na-ekpo ọkụ, nke a pụrụ iji mee ihe dị ka mkpanaka njikwa na ngwaọrụ nchebe na reactors atomic;
4. Hafnium ntụ ntụ nwere ike iji mee ihe dị ka ihe na-eme ka rọketi
5. Enwere ike iji Hafnium mee ihe dị ka onye na-enweta ọtụtụ usoro inflatable.Hafnium getter nwere ike wepu oxygen, nitrogen na gas ndị ọzọ na-enweghị isi dị na sistemụ;
6. A na-ejikarị Hafnium eme ihe dị ka ihe mgbakwunye na mmanụ hydraulic iji gbochie mgbanwe nke mmanụ hydraulic n'oge ọrụ dị egwu.Dị ka Hafnium nwere ike mgbochi volatility, a na-ejikarị ya na mmanụ hydraulic ụlọ ọrụ na mmanụ hydraulic ọgwụ;
7. A na-ejikwa mmewere Hafnium na nhazi Intel45nm kachasị ọhụrụ;
8. Hafnium alloys nwere ike iji dị ka mkpuchi mkpuchi n'ihu maka rocket nozzles na gliding re-abanye ụgbọ ala, na Hf-Ta alloys nwere ike iji rụpụta ígwè ígwè na ihe ndị na-eguzogide.A na-eji Hafnium mee ihe dị ka ihe mgbakwunye na alloys na-eguzogide okpomọkụ, dị ka alloys nke tungsten, molybdenum, na tantalum.Enwere ike iji HfC dị ka ihe mgbakwunye carbide cimented n'ihi nnukwu ike ike ya na ebe agbaze ya.
