Incazelo Yomkhiqizo

I-Hafnium diboride iwuhlobo lwekristalu empunga futhi ine-metallic luster, ene-conductivity kagesi ephezulu kanye nempahla yamakhemikhali ezinzile. Ngaphandle kwalokho, akusabeli neze nawo wonke ama-reagents amakhemikhali (ngaphandle kwe-Hf) kumazinga okushisa angaphakathi. Lona, uhlobo olusha lwensimbi ye-ceramic esebenza kahle kakhulu njengezinga eliphezulu lokuncibilika, izinga lokushisa eliphezulu, i-inoxidizability, njll., isetshenziswa ikakhulukazi emikhakheni efana ne-super high-temperature ceramics, ikhala lendiza enesivinini esikhulu. Ikhoni kanye ne-aerospace, njll.

Isicelo

I-Hafnium diboride iyikristalu ecwebezelayo empunga-mnyama ukwakheka kwayo kwekristalu okuyingxenye yesistimu ene-hexagonal. Njengempahla ye-ceramic yokushisa ephezulu kakhulu eshisa kakhulu, i-hafnium diboride (HfB2) inephuzu lokuncibilika eliphezulu (3380 ℃), ivamise ukusetshenziswa ezintweni ezilwa nokukhipha umoya endaweni ene-oxidation ephezulu futhi inezici zokuqina okuphezulu, ukuphakama okuphezulu. modulus, high conductivity ezishisayo kanye conductivity eliphezulu. Isetshenziswa kabanzi kuma-coatings angagugi, izinto eziphikisayo, amathuluzi okusika kanye nezinhlelo zokuvikela ukushisa kwe-aerospace nezinye izinkambu.
