Ntau yam zoo li cov pa roj carbon monoxide tuaj yeem sib sau ua ke rau hauv ntau qhov kev teeb tsa, Boron Nitride tuaj yeem coj mus rau… [+] Cov qauv ntawm boron nitride hauv nws qhov kev teeb tsa wurtzite muaj zog dua pob zeb diamond Boron nitride kuj tseem siv tau los tsim cov nanotubes, aerogels, thiab ntau yam ntawm lwm cov ntawv thov txaus nyiam.
Puas muaj qhov nyuaj dua pob zeb diamond?
Moissanite, ib txwm tshwm sim silicon-carbide, yuav luag nyuaj li pob zeb diamond. Nws yog ib qho ntxhia tsis tshua muaj, nrhiav pom los ntawm Fab Kis tus kws chemist Henri Moissan hauv xyoo 1893 thaum kuaj cov qauv pob zeb los ntawm lub meteor crater nyob hauv Canyon Diablo, Arizona. Hexagonal boron-nitride yog 18% nyuaj dua pob zeb diamond.
Puas yog Cubic Boron Nitride nyuaj dua pob zeb diamond?
Zoo li ntau cov ntaub ntawv, Boron Nitride muaj nyob rau hauv ntau tshaj ib daim ntawv siv lead ua. Cubic Boron Nitride (CBN): Siab hardness txawm tias kub. … Nyob rau hauv ambient tej yam kev mob tsuas yog h-BN ruaj khov thiab CBN yog metastable.
Puas yog graphene muaj zog dua pob zeb diamond?
Graphene, ntawm qhov tod tes, yog cov ntaub ntawv muaj zog tshaj plaws uas tau sau tseg, ntau dua peb puas npaug zog dua li A36 cov qauv hlau, ntawm 130 gigapascals, thiab ntau tshaj plaub caug npaug zog dua pob zeb diamond.
