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 lwemathiriyeli ye-ceramic enobushushu obuphezulu bokusebenza okubanzi okunjengendawo yokunyibilika ephezulu, ukuhanjiswa kwe-thermal ephezulu, i-inoxidizability, njl. i-cone kunye ne-aerospace, njl.

Isicelo

I-Hafnium diboride yikristale engwevu-emnyama yentsimbi ecwebezelayo enesakhiwo sekristale yenkqubo ye-hexagonal. Njengomgangatho ogqwesileyo we-ultra-high we-ceramic material, i-hafnium diboride (HfB2) inendawo ephezulu yokunyibilika (3380 ℃), ihlala isetyenziswa kwizinto ezichasene nokukhupha izinto kwindawo yobushushu obuphezulu be-oxidation kwaye ineempawu zokuqina okuphezulu, ukuphakama okuphezulu. modulus, high conductivity thermal kunye conductivity eliphezulu. Isetyenziswa ngokubanzi kwiingubo zokugquma, izinto eziphikisayo, izixhobo zokusika kunye neenkqubo zokukhusela ukushisa kwe-aerospace kunye nezinye iinkalo.
