Sharaxaada Alaabta

Hafnium diboride waa nooc ka mid ah crystal cawl oo leh dhalaal macdan ah, oo leh korantada sare iyo hanti kiimikaad deggan. Ka sokow, si dhib leh loogama falceliyo dhammaan reageyaasha kiimikada (marka laga reebo Hf) heerkulka gudaha. Waa, nooc ka mid ah walxo dhoobo ah oo nooc cusub ah oo leh heerkul sare oo waxqabad dhammaystiran sida barta dhalaalaysa sare, kulaylka sareynta, inoxidizability, iwm, ayaa inta badan laga codsadaa beeraha sida dhoobada heer-kulka sare ee sare, sanka diyaaradaha xawaaraha sare leh. koorta iyo hawada hawada, iwm.

Codsiga

Hafnium diboride waa muraayad dhalaalaysa cawl-madow oo dhalaalaysa oo qaab-dhismeedkiisa crystal ka tirsan yahay nidaamka laba geesoodka. Sida maaddada dhoobada heerkulka ultra-sare leh, hafnium diboride (HfB2) waxay leedahay dhibic dhalaalaysa (3380 ℃), waxaa badanaa loo isticmaalaa walxaha anti-ablation ee deegaanka oksaydhka heerkul sare oo leh sifooyinka adagaanta sare, sare. modules, conductivity kaamerada sare iyo conductivity sare. Waxaa si weyn loogu isticmaalaa daahan u adkaysta, alaabta refractory, Qalabka goynta iyo nidaamka ilaalinta kulaylka hawada hawada iyo beeraha kale.
