Graphite thiab pob zeb diamond yog ob hom ntxhia ntawm carbon. … Qhov no muab graphite nws cov hardness tsawg heev, nws zoo meej cleavage, thiab nws txoj kev ntxhib los mos.
Puas yog graphite puas muaj qhov tawg lossis tawg?
Nyob rau hauv graphite, carbon atoms yog teem rau hauv txheej. Graphite muaj cleavage vim tias cov nyiaj tsis muaj zog ntawm cov txheej txheem tawg yooj yim. Ntxiv lub log piav qhia rau pob txha hauv koj phau ntawv.
Puas yog graphite muaj ib qho kev taw qhia ntawm kev tawg?
Pob zeb diamond thiab graphite muab piv txwv ntawm kev sib cais. Ob leeg yog tsim los ntawm ib lub ntsiab lus, carbon. Tab sis nyob rau hauv pob zeb diamond, txhua carbon atom yog bonded rau plaub lwm tus nyob rau hauv ib tug tetrahedral qauv nrog luv luv covalent bonds. … Qhov no muab graphite ib qho kev taw qhia ntawm cleavage, parallel mus rau basal pinacoid.
Tus yam ntxwv ntawm graphite yog dab tsi?
Dab tsi yog cov yam ntxwv ntawm graphite thiab isotropic graphite cov ntaub ntawv? Cov yam ntxwv ntawm graphite muaj xws li siab ua haujlwm rau qhov kub thiab txias thiab tshuaj, zoo heev thermal thiab hluav taws xob conductivity, thiab tiv thaiv kev sib txhuam thiab hnav.
Dab tsi yog qee yam khoom ntawm graphite?
Nws yog qhov tshwj xeeb uas nws muaj cov khoom ntawm ob lub hlau thiab tsis yog hlau: nws hloov tau tab sis tsis elastic, muaj a siab thermal thiab hluav taws xob conductivity, thiab yog heev refractory thiab chemically inert. Graphite muaj qhov tsis tshua muaj adsorption ntawm X-rays thiab neutrons ua nws cov khoom siv tshwj xeeb hauv nuclearkev siv.
