Lub ntsiab nta:

Hafnium diboride (HfB2) yog cov xim txho dub dub nrog cov xim hlau. Nws cov qauv siv lead ua belongs rau hexagonal system. Raws li cov khoom siv ua kom zoo tshaj plaws ultra-high ceramic ceramic,

HfB2 muaj qhov chaw siab melting (3380 ℃), siab huv siab, me me qhov loj me, kev faib khoom tsis sib xws, thaj chaw tshwj xeeb tshwj xeeb, kev ua haujlwm siab ntau, qhov nruab nrab ntom ntom ntom nti, hluav taws xob zoo thiab ruaj khov tshuaj lom neeg. Nws kog tsis tshua muaj txhua qhov tshuaj lom neeg tsuas yog HF ntawm chav sov. Cov ntaub ntawv tshiab cov ntaub ntawv nrog cov nplauv siab, siab thermal conductivity thiab oxidation kuj

Lub ntsiab siv:

Nws yog tsuas yog siv hauv ultra-high temperature ceramics, lub qhov ntswg lub khob ntawm cov dav hlau siab, aviation, huab cua thiab lwm cov teb. Nws yog qhov zoo tshaj plaws neeg sib tw cov ntaub ntawv ntawm ultra-high kub ceramics. Nws yog feem ntau siv los ua anti ablation cov khoom nyob rau hauv high-temperature oxidation ib puag ncig, thiab muaj cov yam ntxwv ntawm siab hardness, siab modulus, siab thermal conductivity thiab siab conductivity.
