Tantalum carbide (TaC)ke sesebelisoa sa ceramic se nang le mocheso o phahameng o phahameng o hanyetsanang le mocheso o phahameng, ho teteana haholo, ho kopana ho phahameng; bohloeki bo phahameng, litaba tse sa hloekang <5PPM; le ho se sebetse ha lik'hemik'hale ho ammonia le hydrogen mocheso o phahameng, le botsitso bo botle ba mocheso.
Seo ho thoeng ke li-ceramics tsa mocheso o phahameng haholo (UHTCs) hangata li bua ka sehlopha sa lisebelisoa tsa ceramic tse nang le sebaka se qhibilihang se fetang 3000 ℃ mme se sebelisoa maemong a mocheso o phahameng le tikoloho e senyang (joalo ka tikoloho ea athomo ea oksijene) ka holimo ho 2000 ℃, joalo ka. ZrC, HfC, TaC, HfB2, ZrB2, HfN, joalo-joalo.
Tantalum carbidee na le ntlha ea ho qhibiliha ho fihla ho 3880 ℃, e na le boima bo phahameng (Mohs hardness 9-10), conductivity e kholo ea mocheso (22W · m-1 · K-1), matla a maholo a ho koba (340-400MPa), le coefficient e nyenyane ea ho atolosa mocheso. (6.6×10-6K-1), mme e bonts'a botsitso bo botle ba thermochemical le thepa e ntle ea 'mele. E na le lik'hemik'hale tse ntle tsa lik'hemik'hale le ho lumellana le mechine le likarolo tsa graphite le C / C. Ka hona,Liaparo tsa TaCli sebelisoa haholo tšireletsong ea mocheso oa sefofane, kholo ea kristale e le 'ngoe, lisebelisoa tsa elektronike tsa matla, le lisebelisoa tsa bongaka.
Tantalum carbide (TaC)ke setho sa lelapa la ceramic la mocheso o phahameng haholo!
Ha lifofane tsa sejoale-joale tse kang likoloi tsa sefofane, lirokete le metsu li ntse li hola ho ea ka lebelo le phahameng, ho sututsa holimo le bophahamo bo phahameng, litlhoko tsa ho hanyetsa mocheso o phahameng le ho hanyetsa oxidation ea thepa ea bona ea bokaholimo tlas'a maemo a feteletseng li ntse li phahama. Ha sefofane se kena sepakapakeng, se tobana le maemo a feteletseng joalo ka mocheso o phahameng oa mocheso, khatello e phahameng ea ho ema, le lebelo la ho phalla ha moea ka potlako, hammoho le ho ntšoa ha lik'hemik'hale ho bakoang ke ho itšoara ka oksijene, mouoane oa metsi le carbon dioxide. Ha sefofane se fofa se tsoa le ho ea sepakapakeng, moea o potolohileng nko ea sona le mapheo a sona a tla hatelloa habohloko ’me a hlahise ho hohlana ho hoholo ha sefofane, ho etsa hore bokaholimo ba sona bo futhumale ke moea. Ntle le ho futhumala ha aerodynamic nakong ea sefofane, bokaholimo ba sefofane bo tla boela bo angoa ke mahlaseli a letsatsi, mahlaseli a tikoloho, joalo-joalo nakong ea sefofane, e leng se etsang hore mocheso oa holim'a sefofane o tsoele pele ho phahama. Phetoho ena e tla ama haholo boemo ba tšebeletso ea sefofane.
Tantalum carbide powder ke setho sa lelapa la ceramic le hananang le mocheso o phahameng haholo. Sebaka sa eona se phahameng sa ho qhibiliha le botsitso bo botle ba thermodynamic bo etsa hore TaC e sebelisoe haholo pheletsong e chesang ea sefofane, mohlala, e ka sireletsa bokaholimo ba mokelikeli oa enjine ea rokete.
