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. Izo, mtundu wa zinthu za ceramic zamtundu watsopano wokhala ndi kutentha kwapamwamba kwambiri monga malo osungunuka kwambiri, matenthedwe apamwamba kwambiri, inoxidizability, ndi zina zotero, amagwiritsidwa ntchito makamaka m'magawo monga zoumba zapamwamba kwambiri, mphuno za ndege zothamanga kwambiri. cone ndi ndege, etc.

Kugwiritsa ntchito

Hafnium diboride ndi kristalo wonyezimira wakuda wachitsulo yemwe mawonekedwe ake amapangidwa ndi hexagonal system. Monga zida zabwino kwambiri zotentha kwambiri za ceramic, hafnium diboride (HfB2) ili ndi malo osungunuka kwambiri (3380 ℃), imagwiritsidwa ntchito nthawi zambiri pazinthu zotsutsana ndi ablation m'malo otentha kwambiri oxidation ndipo imakhala ndi mawonekedwe olimba kwambiri, okwera kwambiri. modulus, high matenthedwe madutsidwe ndi mkulu madutsidwe. Amagwiritsidwa ntchito kwambiri mu zokutira zosamva kuvala, zida zokanira, Zida zodulira ndi makina oteteza matenthedwe amlengalenga ndi magawo ena.
