Yog vim li cas rau cov yam ntxwv zoo ntawm flake graphite

Flake graphite yog siv dav hauv kev lag luam, uas yog los ntawm nws tus kheej cov yam ntxwv zoo. Niaj hnub no, Furuite Graphite Xiaobian yuav qhia koj cov laj thawj rau cov yam ntxwv zoo ntawm flake graphite los ntawm cov yam ntxwv ntawm tsev neeg cov ntsiab lus thiab cov khoom sib xyaw:

Ua ntej, cov yam ntxwv zoo ntawm cov ntsiab lus carbon uas ua rauflake graphite.

1. Cov khoom siv tshuaj lom neeg ntawm cov pa roj carbon monoxide yog qhov ruaj khov ntawm chav tsev kub, thiab nws yog insoluble hauv dej, dilute acid, dilute alkali thiab organic solvents;

2, reacting nrog oxygen ntawm qhov kub thiab txias sib txawv los tsim cov pa roj carbon dioxide lossis carbon monoxide; Hauv halogen, tsuas yog fluorine tuaj yeem cuam tshuam ncaj qha nrog cov pa roj carbon monoxide;

3. Nyob rau hauv cov cua kub, elemental carbon yog yooj yim oxidized los ntawm acid;

4. Thaum kub kub, cov pa roj carbon kuj tuaj yeem ua rau muaj ntau cov hlau los tsim cov hlau carbides;

5. Cov pa roj carbonyog txo qis thiab tuaj yeem siv rau smelt hlau ntawm qhov kub thiab txias.

Thib ob, cov yam ntxwv ntawm cov khoom siv sib xyaw ua ke ntawm flake graphite.

1. Nyob rau hauv graphite siv lead ua, carbon atoms nyob rau hauv tib txheej hybridize nrog sp2 los ua covalent bonds, thiab txhua carbon atom txuas nrog peb lwm atoms los ntawm peb covalent bonds. Rau cov pa roj carbon atoms tsim ib lub nplhaib hexagonal ntawm tib lub dav hlau, ncab mus rau hauv cov txheej txheem txheej, qhov twg daim ntawv cog lus ntev ntawm CC daim ntawv cog lus yog tag nrho 142 teev, uas belongs rau daim ntawv cog lus ntev ntawm atomic siv lead ua, yog li rau tib txheej, nws yog ib qho atomic. siv lead ua.

2. Cov khaubncaws sab nraud povtseg ntawm graphite crystals yog sib cais los ntawm 340pm, uas yog ib tug loj nyob deb, thiab yog ua ke los ntawm van der Waals quab yuam, uas yog, cov khaubncaws sab nraud povtseg yog molecular crystals. Txawm li cas los xij, vim muaj kev sib raug zoo ntawm cov pa roj carbon atoms hauv tib lub dav hlau txheej, nws yog qhov nyuaj heev los rhuav tshem, yog li lub melting point ntawmgraphitekuj yog siab thiab nws cov tshuaj muaj zog ruaj khov.
