Hafnium carbide
Fa'amatalaga
Hafnium carbide (HfC), lanu efuefu ma u'amea luster, ua lauiloa e maualuga lona tulaga fa'afefeteina o se tasi fa'afefiloi, ma o se mea lelei mo u'amea u'amea u'amea fa'alava. Faʻatasi ai ma le maualuga o le liusuavai, maualuga le maaa, maualuga le malosi o le vevela, lelei le pala ma le maualalo o le vevela, i le vevela o le 1900 ~ 2300 ℃, hafnium carbide ma isi paʻu carbide (e pei o le ZrC, TaC, ma isi) faia se vaifofo mautu, e mafai ona faʻaaogaina e fai ma faʻaopoopoga mo uʻamea malo, faʻaaogaina lautele i le fanua o mea faigaluega tipi ma faʻailoga; E talafeagai foi mo mea o roketi nozzles, e mafai ona faʻaaogaina i le isu o roketi, e masani ona faʻaaogaina i le aerospace; ae e mafai foi ona faʻaaogaina i totonu o le pupuni, maualuga le vevela faʻafefeteina lining, arc poʻo electrolytic electrode; E mafai fo'i ona fa'aoga mo tooto'o fa'atonu fa'aola faaniukilia.
