Nano Hafnium carbide HfC ntụ ntụ
1. Njirimara nke ihe hafnium carbide:
(1) Hafnium carbide (HfC) bụ ntụ ntụ ojii na-acha ntụ ntụ nwere usoro cubic nwere ihu na ebe mgbaze dị elu (3890°C).Ọ bụ ihe nwere ebe mgbaze dị elu na otu ogige a ma ama na ọ bụ nnukwu ihe na-agbaze ígwè na-agbaze crucible lining.Ezigbo ihe.
(2) N'ime ihe ndị a ma ama, hafnium alloy (Ta4HfC5) nwere nnukwu agbaze bụ hafnium alloy (Ta4HfC5).Ihe hafnium alloy nke 1 akụkụ nke hafnium carbide na akụkụ anọ nke tantalum carbide nwere ebe mgbaze nke 4215 ℃, yabụ enwere ike iji ya dị ka ihe eji arụ ọrụ na injin jet na daodan.
(3) Hafnium carbide nwere ọnụọgụ ọkụ dị elu nke ọkụkọ, ezigbo ọkụ eletrik na ọkụ ọkụ, obere ọnụọgụ mgbasawanye ọkụ na mmetụta dị mma.Ọ dabara adaba maka mpaghara ihe mkpuchi rọketi ma bụrụkwa ihe cermet dị mkpa.

3. Ojiji hafnium carbide:
(1) Hafnium carbide bụ ihe na-eguzogide okpomọkụ dị elu, ihe seramiiki na-eguzogide yanghua, nke nwere uru nke ọkụ eletrik dị mma na ọkụ ọkụ na mgbasawanye ọkụ dị ala.Hafnium carbide dabara adaba maka imepụta akụkụ dị mkpa dị ka roket nozzles na nku nku, a na-ejikwa ya na hangian, ceramics ụlọ ọrụ na mpaghara ndị ọzọ.
(2) Hafnium carbide nwere ike siri ike, enwere ike iji ya dị ka ihe mgbakwunye carbide cemented, nwere ike ịmepụta ngwọta siri ike na ọtụtụ ogige (dị ka ZrC, TaC, wdg), ma jiri ya mee ihe n'ọtụtụ ebe n'ọhịa nke ịkpụ ngwá ọrụ na ịkpụzi.
(3) Hafnium carbide nwere ọnụọgụ na-agbanwe dị elu, ezigbo ọkụ eletrik na ọkụ ọkụ, obere ọnụọgụ mgbasawanye ọkụ na mmetụta dị mma.Ọ dị mma maka ihe mkpuchi rọketi ma enwere ike iji ya na cone imi nke rọketi.Ọ nwere ngwa dị mkpa na mpaghara ikuku.Enwekwara ngwa dị mkpa na nozzles, mkpuchi na-eguzogide okpomọkụ, electrodes maka arc ma ọ bụ electrolysis.
(4) Hafnium carbide nwere ezigbo nkwụsi ike nke usoro siri ike, nguzogide kemịkalụ, ma nwee ike ịdị mma maka ojiji na gburugburu oke okpomọkụ.Na mgbakwunye, ikpochapụ ihe nkiri HfC n'elu carbon nanotube cathode nwere ike imeziwanye arụmọrụ ikuku ya.
(5) Mgbakwunye hafnium carbide na C / C composites nwere ike imeziwanye nkwụsị nkwụsị ya.Hafnium carbide nwere ọtụtụ ọmarịcha anụ ahụ na kemịkalụ, na-eme ka a na-eji ya eme ihe n'ụdị chao dị elu ugbu a.
