CAS 12069-85-1 Hafnium Carbide Hmoov Hfc hmoov nqe
Khoom npe: Hfc hmoov nqeHafnium Carbide Hmoov
Kev piav qhia ntawm HFC hmoov
Hafnium carbide (HFC hmoov) yog qhov sib txuas ntawm cov carbon thiab hafnium. Nws lub ntsiab lus melting yog kwv yees li ntawm 3900 ° C, uas yog ib qho ntawm feem ntau refractory binary paub. Txawm li cas los xij, nws oxidation tsis kam yog tsawg heev, thiab oxidation pib ntawm qhov kub thiab txias li 430 ° C.
HFC hmoov yog xim dub, grey, brittic loj; thaj tsam siab hla kev nqus thermal neutrons; resistivity 8.8μohm ·; cov feem ntau refractory binary cov khoom paub; Hardness 2300kgf / mm2; siv nyob rau hauv nuclear reactor tswj cov pas nrig; Nws tau npaj los ntawm cua sov HFO2 nrog roj ntxiv hauv qab H2 ntawm 1900 ° C-2300 ° C-2300 ° C-2300 ° C. Nws yog siv nyob rau hauv daim ntawv ntawm crucible mus rau yaj oxide thiab lwm tus oxides.
