Hafnium Carbide HfC |Zirconium Carbide ZrC

Inkcazo

IHafnium Carbide HfC, a grey-black metallic luster powder eqinileyo, CAS No.12069-85-1, kunye nobunzima bemolekyuli 190.5, indawo yokunyibilika 3890 ° C kunye noxinzelelo 12.7g / cm³, enganyibilikiyo emanzini, kodwa i-soluble kwi-hydrofluoric acid, i-soluble concentrated sulfuric acid, i-nitric acid okanye isisombululo se-alkaline eshushu, kwaye izinzile kwiqondo lokushisa.I-Hafnium Carbide HfC ibonisa ukuzinza kweekhemikhali kunye nepropathi ephezulu yokushisa okuphezulu, indawo ephezulu yokunyibilika, i-coefficient ephezulu ye-elastic, i-conductivity efanelekileyo yombane, ukwandiswa okuncinci kwe-thermal kunye nepropathi efanelekileyo yempembelelo, ubunzima obuphezulu kunye nokuqina, kunye nokumelana ne-oxidation.I-Hafnium Carbide HfC kunye ne-Zirconium Carbide ZrC kwi-Western Minmetals (SC) Corporation inokuhanjiswa ngobukhulu bepowder 0.5-500 micron okanye i-5-400 ye-mesh okanye njengoko kuchaziwe ngokwezifiso, iphakheji ye-25kg, i-50kg kwingxowa yeplastiki enegubu lentsimbi ngaphandle.

Usetyenziso

I-Hafnium Carbide HfC ingasetyenziselwa ukongeza kwimveliso ye-carbide enesamente ukuthintela ngokufanelekileyo ukukhula okuziinkozo kunye nokusetyenziswa ngokubanzi kwintsimi yezixhobo zokusika.Njengesixhobo esibalulekileyo sendawo yokunyibilika okuphezulu, ukomelela okuphezulu kunye nokuchasana nokubola, iHafnium Carbide HfC isetyenziswa ikakhulu kwiindawo zombhobho we-aerospace, i-alloy eqinile, intonga yokulawula i-nyukliya kumandla eathom efayiliweyo, i-arc okanye i-electrode yokumelana nobushushu obuphezulu. i-electrolysis, ishishini lombane, ifilim ebhityileyo, isinyithi, i-ceramic kunye nolunye ushishino njl.

Zirconium Carbide ZrC, i-gray metallic powder kunye ne-cubic lattice system structure ye-NaCl Type, i-molecular 103.22, i-melting point 3540 ° C, indawo yokubilisa i-5100 ° C, ubuninzi be-6.73g / cm³, isabela ngamanzi kodwa inyibilika kwiasidi, iyipropathi ebalaseleyo yobushushu obuphezulu.

Nge-anti-oxidation elungileyo, ukuhanjiswa kwe-thermal kunye nokuqina, isetyenziswa kakhulu njengamandla aphezulu aphezulu, i-anti-corrosive, ubushushu obuphezulu besakhiwo kunye ne-welding ye-thermal spray coating material.I-powder ye-ZrC efanelekileyo yinto ebalulekileyo ye-cermet yesixhobo sokusika kwi-alloy enzima, amandla e-athomu, izixhobo zombane njl njl. I-Zirconium Carbide nayo luhlobo lwezinto ezinyibilikayo eziphezulu ezinobunzima obuphezulu kunye ne-refractory ephezulu yokushisa, enokusetyenziswa njengento eluhlaza. imathiriyeli ye-propellant eyomeleleyo kwi-rocket motor kumzi-mveliso we-aerospace, imathiriyeli ekrwada yokwenziwa kwentsimbi ye-zirconium kunye ne-zirconium tetrachloride, kunye nezinye izinto ezithembisayo zeceramic.
