I-Nano Hafnium carbide HfC powder
1. Izici zezinto ze-hafnium carbide:
(1) I-Hafnium carbide (HfC) iyimpushana empunga-mnyama enesakhiwo se-cubic esigxile ebusweni kanye nendawo yokuncibilika ephakeme kakhulu (3890°C). Yimpahla enephuzu elincibilikayo eliphezulu esakhiweni esisodwa esaziwayo futhi iyindawo ephezulu yokuncibilika yensimbi encibilika ulwelwesi oluncibilikayo. Izinto ezinhle.
(2) Phakathi kwezinto ezaziwayo, i-hafnium alloy (Ta4HfC5) enephuzu eliphakeme lokuncibilika i-hafnium alloy (Ta4HfC5). I-hafnium alloy material yengxenye engu-1 ye-hafnium carbide kanye nezingxenye ezi-4 ze-tantalum carbide inendawo encibilikayo engu-4215 ℃, ngakho ingasetshenziswa njengesakhiwo sezinjini zejethi nedaodan.
(3) I-Hafnium carbide ine-coefficient ephezulu yokunwebeka yesikhukhukazi, i-conductivity enhle kagesi kanye ne-thermal, i-coefficient encane yokwandisa ukushisa kanye nokumelana nomthelela omuhle. Ilungele inkambu yezinto zokwakha ze-rocket nozzle futhi iyinto ebalulekile ye-cermet.

| Ibanga | Usayizi Oyingxenye(nm) | Ubumsulwa(%) | I-SSA(m2 /g) | Ukuminyana(g/cm 3) | Isakhiwo Sekristalu | Umbala |
| I-Nanometer | 100nm 0.5-500um,1-400mesh | >99.9 | 15.9 | 3.41 | ihexagon | Mnyama |
3. Ukusetshenziswa kwe-hafnium carbide:
(1) I-Hafnium carbide iwukumelana nezinga lokushisa eliphezulu, i-yanghua ukumelana ne-ceramic impahla, enezinzuzo ze-conductivity enhle kagesi kanye ne-thermal kanye nokwanda okuphansi kokushisa. I-Hafnium carbide ifaneleka ukukhiqiza izingxenye ezibalulekile ezifana nama-rocket nozzles nama-wing fronts, futhi isetshenziswa kakhulu kuma-hangtian, izitsha zobumba zezimboni nezinye izinkambu.
(2) I-Hafnium carbide inobunzima obuphezulu, ingasetshenziswa njengezithasiselo ze-carbide ezinosimende, ingenza isisombululo esiqinile ngezinhlanganisela eziningi (njenge-ZrC, i-TaC, njll.), futhi isetshenziswe kabanzi emkhakheni wokusika amathuluzi nokubunjwa.
(3) I-Hafnium carbide ine-coefficient ephezulu yokunwebeka, i-conductivity enhle kagesi kanye ne-thermal, i-coefficient encane yokwandisa ukushisa kanye nokumelana nomthelela omuhle. Ilungele izinto zokwakha ze-rocket nozzle futhi ingasetshenziswa ku-cone yekhala yamarokhethi. Inezinhlelo zokusebenza ezibalulekile emkhakheni we-aerospace. Kukhona nezinhlelo zokusebenza ezibalulekile kuma-nozzles, ama-linings ukumelana nezinga lokushisa eliphezulu, ama-electrode e-arc noma i-electrolysis.
(4) I-Hafnium carbide inokuqina okuhle kwesigaba esiqinile, ukumelana namakhemikhali, futhi inamandla okufanelekela ukusetshenziswa ezindaweni ezinezinga lokushisa eliphezulu. Ngaphezu kwalokho, ukuhwamuka kwefilimu ye-HfC endaweni ye-carbon nanotube cathode kungathuthukisa kakhulu ukusebenza kwayo kokukhipha insimu.
(5) Ukwengezwa kwe-hafnium carbide kuzinhlanganisela ze-C/C kungathuthukisa ukumelana kwayo nokukhishwa kwe-ablation. I-Hafnium carbide inezinto eziningi ezinhle kakhulu zomzimba namakhemikhali, okwenza isetshenziswe kabanzi ezintweni zamanje ze-chao ezisezingeni eliphezulu.
