Incazelo

I-Niobium Carbide NbC,impushana ensundu ngokukhanyayo, enohlobo lwe-sodium chloride uhlobo lwe-cubic crystal system, indawo encibilikayo engu-3490°C, indawo yokubilisa engu-4300°C, ukuminyana 7.56g/cm³, ayincibiliki emanzini naku-asidi ye-inorganic, kodwa incibilika ku-asidi exubile ye-hydrofluoric acid ne-nitric acid futhi ingabola.I-Niobium Carbide ayikwazi kuphela ukusetshenziswa njengesengezo ukuvimbela ukukhula kwezinhlamvu ze-alloy ukuhlawulisa okusanhlamvu kwe-carbide crystalline kasimende ekukhiqizeni i-carbide enosimende, kodwa futhi yakha isigaba sesithathu esihlakazekile namanye ama-carbides ngaphandle kwe-WC ne-Co, engathuthuka kakhulu. ubulukhuni bokushisa, ukumelana nokushisa okushisayo, ukumelana nokucindezela okushisayo kanye nokumelana ne-oxidation ye-carbide enosimende.Ngezinzuzo zokuthuthukisa ubulukhuni nokuqina kokuphuka kwe-alloy, ingasetshenziswa ukulungisa izinto zamathuluzi e-carbide enosimende ngokusebenza okuhle kakhulu kokusika.Ngaphandle kwalokho, iyindawo ephakeme yokuncibilika, ubulukhuni obuphezulu kanye nokuzinza kwamakhemikhali, i-NbC iphinde isetshenziswe njengempahla ephikisayo yokushisa ephezulu kanye nempahla yokufutha embonini ye-aerospace.

Ukulethwa

I-Niobium Carbide NbC kanye ne-Tantalum Carbide TaC e-Western Minmetals (SC) Corporation zingalethwa ngosayizi wempushana engu-0.5-500 micron noma 5-400 mesh noma njengokucaciswa okungokwezifiso, iphakheji engu-25kg, 50kg esikhwameni sepulasitiki nesigubhu sensimbi ngaphandle.

I-Tantalum Carbide TaC, i-powder yombala onsundu, isakhiwo se-cubic crystal sohlobo lwe-sodium chloride, isisindo samangqamuzana 192.96, ukuminyana 14.3g/cm³, iphoyinti lokuncibilika elingu-3880°C, iphoyinti elibilayo elingu-5500°C, alincibiliki emanzini nama-asidi angaphili, futhi lingancibilika kungxube ye-hydrofluoric acid ne-nitric acid bese libola.I-Tantalum Carbide idlala indima ebalulekile ekuvimbeleni ukukhula okusanhlamvu futhi ithuthukise ubulukhuni obubomvu kanye nokugqoka ukumelana kwengxubevange, ithuthukise ukumelana ne-oxidation kanye nokumelana nokugqwala kwe-alloy kanye nokwenza ngcono ukwakheka kwengxubevange.Ngokuzinza kwamakhemikhali aphezulu kanye nohlamvu oluphezulu lokushisa, i-TaC iyisengezo esibalulekile kuzinhlamvu ezicwebezelayo ze-WC zethuluzi lokusika elinobulukhuni obukhulu obufana nedayimane.Ingase futhi inikeze ukumelana okukhulu nezinga lokushisa elifinyelela ku-3880 ° C, futhi ithola ukusetshenziswa okubanzi emikhakheni efana nama-alloys aqinile, okuhlosiwe, izinto zokushisela, ama-cermets, i-electronics, imishini kanye nemboni yezindiza.
