Dab tsi ntawm tus neeg xyuas pib yog carbon graphite?

Carbon graphite yog tus neeg xyuas pib, thiab nws cov khoom siv hluav taws xob feem ntau yog muab los ntawm nws cov qauv siv lead ua tshwj xeeb thiab cov tshuaj muaj pes tsawg leeg. Graphite yog ib qho allotrope ntawm carbon. Txhua cov pa roj carbon atom txuas nrog peb lwm cov pa roj carbon atom nyob ib puag ncig nws, tsim cov qauv honeycomb zoo li hexagonal thiab sib txuas los ntawm covalent bonds. Txij li thaum txhua cov pa roj carbon atom tso tawm ib qho hluav taws xob, cov hluav taws xob no tuaj yeem txav tau yooj yim hauv txheej graphite, ua rau graphite muaj cov khoom siv hluav taws xob zoo, tshwj xeeb tshaj yog hauv cov khoom siv hluav taws xob thiab cov roj teeb. Tsis tas li ntawd, graphite muaj lwm yam zoo ntawm lub cev thiab tshuaj lom neeg, xws li cov khoom siv tshuaj ruaj khov, kub tsis kam, corrosion resistance, thermal shock resistance, radiation resistance, siab zog, zoo toughness thiab self-lubrication. Cov khoom no ua graphite dav siv hauv metallurgy, machinery, electronics, tub rog kev lag luam, tiv thaiv lub teb chaws, aerospace thiab lwm yam kev lag luam.
