Ingcaciso yeMveliso

I-Hafnium diboride luhlobo lwekristale engwevu kwaye ine-metallic luster, ene-conductivity ephezulu yombane kunye nepropathi ezinzileyo yeekhemikhali. Ngaphandle koko, ayisabeli nazo zonke ii-reagents zekhemikhali (ngaphandle kwe-Hf) kubushushu bangaphakathi. Yona, luhlobo olutsha lwezixhobo ze-ceramic ezinobushushu obuphezulu bokusebenza okubanzi okunje ngenqanaba lokunyibilika okuphezulu, i-thermal conductivity ephezulu, i-inoxidizability, njl.

Isicelo

I-Hafnium diboride yikristale yentsimbi engwevu-emnyama enekristale enesakhiwo sekristale yenkqubo ye-hexagonal. Njengomgangatho obalaseleyo we-ultra-high we-ceramic material, i-hafnium diboride (HfB2) inendawo ephezulu yokunyibilika (3380 ℃), isoloko isetyenziswa kwizinto ezichasene ne-ablation kwindawo ye-oxidation yobushushu obuphezulu kwaye ineempawu zobunzima obuphezulu, i-modulus ephezulu, i-conductivity ephezulu ye-thermal kunye ne-conductivity ephezulu. Isetyenziswa ngokubanzi kwiingubo ezinqabileyo zokunxiba, izinto eziphikisayo, izixhobo zokusika kunye neenkqubo zokukhusela ukushisa kwe-aerospace kunye nezinye iinkalo.
