Khoom npe:HfC hmoovNqeHafnium Carbide hmoov
Kev piav qhia ntawm HfC Hmoov
Hafnium carbide (HfC Powder) yog qhov sib xyaw ntawm cov pa roj carbon thiab hafnium. Nws cov ntsiab lus melting yog txog 3900 ° C, uas yog ib qho ntawm feem ntau refractory binary compounds paub. Txawm li cas los xij, nws cov oxidation tsis kam yog tsawg heev, thiab oxidation pib ntawm qhov kub thiab txias li 430 ° C.
HfC hmoov yog xim dub, grey, nkig; siab cross-section absorbs thermal neutrons; resistivity 8.8μohm · cm; feem ntau refractory binary khoom paub; hardness 2300kgf / mm2; siv nyob rau hauv nuclear reactor tswj rods; Nws yog npaj los ntawm cua sov HfO2 nrog roj soot hauv qab H2 ntawm 1900 ° C-2300 ° C. Nws yog siv nyob rau hauv daim ntawv ntawm crucible rau yaj oxide thiab lwm yam oxides.
