A: Nqe lus piav qhia. Ntshiab graphite yog ib daim ntawv ntxhia ntawm cov khoom carbon (element #6, cim C). Nws tsim raws li cov hlab ntsha thiab kev nthuav tawm hauv cov pob zeb metamorphic raws li qhov tshwm sim ntawm metamorphism ntawm cov khoom siv organic suav nrog hauv limestone deposits.

Q: Dab tsi dissolves graphite?

A: Graphite yog insoluble hauv dej thiab organic solvents - rau tib yam vim li cas pob zeb diamond yog insoluble. Attractions ntawm hnyav molecules thiab carbon atoms yuav tsis muaj zog txaus los kov yeej cov muaj zog covalent bonds nyob rau hauv graphite. Graphite txawm li cas los xij, yog soluble hauv molten nickel thiab sov chlorosulfuric acid.

Q: Cov teeb meem dab tsi daws tau graphite?

A: Ntawm ntau daim ntawv thov, ntuj thiab hluavtaws graphite yog siv rau electrodes, refractories, roj teeb thiab lubricants thiab los ntawm foundries. Coated spherical graphite yog siv los tsim cov anode hauv lithium-ion roj teeb. High-grade graphite kuj tseem siv rau hauv roj hlwb, semiconductors, LEDs thiab nuclear reactors.

Q: Dab tsi temp ua graphite ci?

A: Thov nco ntsoov tias cov khoom tsis kho tau pib yaj hauv daim duab ntawm 1,400 F rau 3 teev. Ua haujlwm ntawm cov kub no, cov graphite yeej muaj cov txiv kab ntxwv ci.

Q: Qhov twg graphite pom?

A: Graphite feem ntau pom zoo li flakes lossis crystalline txheej hauv cov pob zeb metamorphic xws li marble, schist's thiab gneisses. Graphite kuj tseem tuaj yeem pom hauv cov organic-nplua nuj shale's thiab thee txaj. Nyob rau hauv cov ntaub ntawv no, lub graphite nws tus kheej tej zaum yuav tshwm sim los ntawm metamorphosis ntawm cov nroj tsuag tuag thiab tsiaj teeb meem.

Q: Vim li cas graphite dub?

A: Hauv cov thee thiab graphite, lub teeb tau daig ntawm cov atoms, uas yog vim li cas lawv saib tsaus thiab opaque.

Q: Puas yog graphite siv lead ua?

A: Graphite yog crystalline daim ntawv ntawm cov khoom carbon. Nws muaj cov txheej txheej ntawm graphene. Graphite tshwm sim ib txwm muaj thiab yog daim ntawv ruaj khov tshaj plaws ntawm cov pa roj carbon monoxide raws li tus qauv.
