yog graphite sib nqus los yog tsis sib nqus

graphite yog non-magnetic.

Graphite yog ib hom carbon uas paub txog nws cov hluav taws xob zoo heev. Nws yog tsim los ntawm cov khaubncaws sab nraud povtseg ntawm carbon atoms teem nyob rau hauv ib tug hexagonal lattice qauv. Cov khaubncaws sab nraud povtseg yog tuav ua ke los ntawm cov tsis muaj zog van der Waals, uas ua rau graphite cov khoom muag muag thiab flaky.

Tsis zoo li cov ntaub ntawv xws li hlau thiab npib tsib xee, uas muaj zog sib nqus, graphite tsis nyiam cov hlau nplaum. Qhov no yog vim graphite tsis muaj kev txiav txim ntawm lub sijhawm sib nqus hauv nws cov qauv siv lead ua. Nyob rau hauv lwm yam lus, cov electrons nyob rau hauv graphite tsis tag nrho cov tig nyob rau hauv tib txoj kev, yog li cov khoom tsis muaj ib tug net sib nqus lub sij hawm.

Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias tsis yog txhua hom carbon tsis yog hlau nplaum. Piv txwv li, pob zeb diamond kuj yog tsim los ntawm cov pa roj carbon atoms, tab sis nws cov qauv siv lead ua tau raug txiav txim siab heev, ua rau nws diamagnetic (tsis muaj zog los ntawm cov hlau nplaum) ntawm qhov kub thiab txias.
