Hafnium boride (HfB₂) ndi zida za ceramic zomwe zimadziwika ndi zinthu zake zapadera, kuphatikiza kuuma kwakukulu, malo osungunuka kwambiri, komanso kutenthetsa bwino kwamagetsi ndi magetsi. Ndi m'banja la zoumba zotentha kwambiri (UHTCs), zomwe zimagwiritsidwa ntchito m'malo ovuta kwambiri monga mlengalenga ndi chitetezo.

Mafotokozedwe Akatundu

Hafnium diboride ndi mtundu wa kristalo wotuwa ndipo imakhala ndi zitsulo zonyezimira, zokhala ndi magetsi apamwamba komanso katundu wokhazikika wamankhwala. Kupatula apo, sichimakhudzidwa ndi ma reagents onse amankhwala (kupatula Hf) pakutentha kwamkati. Izi, mtundu wa zinthu za ceramic zamtundu watsopano wokhala ndi kutentha kwakukulu kokwanira monga kusungunuka kwapamwamba, kutenthetsa kwapamwamba, kutsekemera kwa inoxidizability, ndi zina zotero, zimagwiritsidwa ntchito makamaka m'madera monga zoumba zotentha kwambiri, mphuno yapamphuno ya ndege yothamanga kwambiri, ndi zina zotero.

Kugwiritsa ntchito

Hafnium diboride ndi kristalo wonyezimira wakuda wachitsulo yemwe mawonekedwe ake amapangidwa ndi hexagonal system. Monga zida zabwino kwambiri za ceramic zotentha kwambiri, hafnium diboride (HfB2) ili ndi malo osungunuka kwambiri (3380 ℃), imagwiritsidwa ntchito nthawi zambiri pazinthu zotsutsana ndi ablation m'malo otentha kwambiri a okosijeni ndipo imakhala ndi mawonekedwe a kuuma kwambiri, modulus yayikulu, matenthedwe apamwamba komanso ma conductivity apamwamba. Amagwiritsidwa ntchito kwambiri pazovala zosagwira ntchito, zida zokanira, Zida zodulira ndi makina oteteza matenthedwe amlengalenga ndi magawo ena.
