Hoobkas Nqe HfB2 Hafnium Diboride Powder
Product Description
Hafnium diboride (HfB2) yog grey-dub siv lead ua nrog nws cov luster, thiab nws cov qauv siv lead ua yog nyob rau hauv hexagonal system.Nws cov khoom siv tshuaj yog ruaj khov, thiab nws tsis tshua muaj kev cuam tshuam nrog txhua yam tshuaj reagents (tshwj tsis yog HF) ntawm chav tsev kub.Raws li ib qho zoo heev ultra-siab kub ceramic cov ntaub ntawv, hafnium diboride muaj ib tug heev melting point (3380 ° C), thiab feem ntau yog siv los ua ib tug anti-ablation khoom nyob rau hauv high-kub oxidizing ib puag ncig.Nws kuj muaj cov yam ntxwv ntawm siab hardness, siab modulus, siab thermal conductivity thiab siab hluav taws xob conductivity, yog li nws yog dav siv nyob rau hauv hnav-resistant coatings, cov ntaub ntawv refractory, txiav cov cuab yeej thiab aerospace thermal tiv thaiv systems thiab lwm yam teb.
