Iyini i-titanium diboride target?

Ithagethi ye-Titanium diboride yenziwe nge-titanium diboride. I-Titanium diboride iwuhlobo olumnyama olumpunga noma olumpunga olune-hexagonal (AlB2) crystal structure, indawo yokuncibilika efinyelela ku-2980 ° C, ukuminyana okungu-4.52g/cm³, kanye nokuqina okuncane okungu-34Gpa, ngakho inokuqina okuphezulu kakhulu.ess. Ine-oxiizinga lokushisa lokumelana ne-dation elifika ku-1000℃ emoyeni, futhi lihlala lizinzile kuma-HCl nama-HF acid, okubonisa ukumelana nokugqwala kwe-asidi okuhle kakhulu.Izakhiwo zezinto ezibonakalayo zimi kanje: i-coefficient yokwandisa ukushisa: 8.1×10-6m/m·k; I-Thermal conductivity: 25J/m·s·k; Ukumelana: 14.4μΩ·cm;

Le nto futhi ine-conductivity enhle yokushisa nogesi, ngakho-ke isetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni, njenge-vacuum coating, amathuluzi okusika i-ceramic kanye nezibunji, ukushisa okuphezulu kwe-crucible, izingxenye zenjini nokunye. Ngesikhathi esifanayo, i-titanium diboride target nayo iyinhloso ebalulekile yokulungiswa kwama-alloys e-titanium, i-ceramics yokuqina okuphezulu nokuqinisa ukhonkolo.

 Indlela yokukhiqiza i-titanium diboride target?

I-1.Indlela yokuhlanganiswa okuqondile: Le ndlela iwukuhlanganisa ngokuqondile i-titanium ne-boron powder ku-reactor ephezulu yokushisa ukuze kukhiqizwe i-titanium diboride. Nokho, izinga lokushisa lokusabela lale ndlela lidinga ukuba ngaphezu kuka-2000℃, intengo yezinto ezibonakalayo iphezulu, inqubo akulula ukuyilawula, ukusabela akuphelele, i-TiB2 ekhiqiziwe iphansi ngokuhlanzeka, futhi kulula ukukhiqiza i-TiB, i-Ti2B nezinye izinhlanganisela.

2.Indlela ye-Borothermal: Le ndlela isebenzisa i-TiO2 (ubumsulwa obungaphezu kuka-99%, ukwakheka kwe-ase, usayizi wezinhlayiyana 0.2-0.3μm) kanye ne-amorphous B (ubumsulwa 92%, usayizi wezinhlayiyana 0.2-0.3μm) njengezinto zokusetshenziswa, ngokusebenzisa isilinganiso esithile kanye inqubo yokugaya ibhola (imvamisa yenziwa ngaphansi kwe-vacuum), ekushiseni okungaphezu kuka-1100 ° C ukulungisa i-titanium diboride.

3.Ncibilikisa i-electrolysis: Kule ndlela, i-titanium oxides isabela nge-alkali (noma umhlaba we-alkali) wensimbi kanye nama-fluorates ngaphansi kwezimo zokuncibilika kwe-electrolysis ukuze akhe i-titanium dib.hamba.
Ngayinye yalezi zinqubo zokukhiqiza inezici zayo, ukukhetha okuqondile ukuthi iyiphi inqubo encike esidingweni sokukhiqiza, izimo zemishini kanye nezindleko zomnotho nezinye izici.

Yiziphi izinkambu zokusetshenziswa kwethagethi ye-titanium diboride?

Izindawo eziyinhloko zokusetshenziswa kwethagethi ye-titanium diboride zibanzi kakhulu, ikakhulukazi ezihlanganisa izici ezilandelayo:

Amathuluzi okusika i-Ceramic nokubunjwa: ingakwazi ukwenza amathuluzi okuqedela, umdwebo wezintambo uyafa, i-extrusion iyafa, iziqhumane zesihlabathi, izakhi zokuvala, njll.
Izinto ze-ceramic ezihlanganisiwe: i-titanium diboride ingasetshenziswa njengengxenye ebalulekile yezinto ezihlanganisiwe zezingxenye eziningi, kanye ne-TiC, i-TiN, i-SiC nezinye izinto ezakhiwe ngezinto ezihlanganisiwe, ukukhiqizwa kwezingxenye ezihlukahlukene zokushisa okuphezulu kanye nezingxenye zokusebenza, ezifana nokushisa okuphezulu. I-crucible, izingxenye zenjini, njll. Futhi ingenye yezinto ezihamba phambili zokwenza izinto zokuvikela izikhali.
I-Cathode coating material ye-aluminium electrolyzer: Ngenxa yokumanzisa okuhle kwe-TiB2 noketshezi lwe-aluminium yensimbi, ukusebenzisa i-titanium diboride njenge-cathode coating material ye-aluminium electrolyzer kunganciphisa ukusetshenziswa kwamandla kwe-aluminium electrolyzer futhi kwandise impilo ye-electrolyzer.
I-PTC yokushisa izinto zobumba ze-ceramic nezinto eziguquguqukayo ze-PTC: i-titanium diboride ingenziwa ngalezi zinto, ngokuphepha, ukonga amandla, okuthembekile, ukucubungula okulula kanye nezici zokwakha, iwuhlobo lwemikhiqizo ebuyekeziwe ye-high-tech yazo zonke izinhlobo zezinto zokushisa zikagesi.
I-ejenti yokuqinisa impahla yensimbi: I-Titanium diboride iyi-ejenti enhle eqinisayo ye-A1, Fe, Cu nezinye izinto zensimbi.
I-Aerospace: I-Titanium diboride ingasetshenziswa ukwenza ama-rocket nozzles, amagobolondo emikhumbi-mkhathi nezinye izakhi ukuze zimelane nezinga lokushisa eliphezulu nezimo zengcindezi.
Inkambu yokuphatha okushisayo: I-Titanium diboride ine-conductivity enhle kakhulu yokushisa futhi ingasetshenziswa njengento yokukhipha ukushisa kumadivayisi we-elekthronikhi, eqhuba kahle ukushisa kurediyetha ukuze kuqinisekiswe ukusebenza okuvamile kwemishini kagesi.
Ukubuyiselwa kwamandla nokonga amandla: I-Titanium diboride ingase isetshenziselwe ukwenza izinto ze-thermoelectric eziguqula amandla okushisa abe ugesi.
Ngaphezu kwalokho, izinhloso ze-titanium diboride nazo zisetshenziswa kabanzi kwezezimoto, ze-elekthronikhi, amandla amasha, amasekethe ahlanganisiwe, ukugcinwa kolwazi nezinye izimboni.

Ingakanani ithagethi ye-titanium diboride?

Intengo yezinhloso ze-titanium diboride iyahlukahluka kuye ngohlobo, ubumsulwa, usayizi, usayizi wezinhlayiyana, ukucaciswa kwephakheji nezinye izici.Ngokwengcaphuno yabanye abahlinzeki, intengo ingasukela emashumini iye ezinkulungwaneni zamayuan. Isibonelo, intengo yezinye iziqondiso ze-titanium diboride ngu-85 yuan, 10 yuan (ucwaningo lwesayensi lokuhlola), 285 yuan (granular) 2000 yuan okuqondiwe noma ngaphezulu (ukuhlanzeka okuphezulu, i-magnetron sputtering). Kufanele kuqashelwe ukuthi lezi ntengo zingamanani okubhekisela kuphela, inani langempela lingashintsha ngenxa yokutholakala kwemakethe kanye nesidingo, ukushintshashintsha kwentengo yempahla eluhlaza kanye nezinye izici.

Ungakhetha kanjani ikhwalithi ephezulu yethagethi ye-titanium diboride?
