Sei graphi graphi is a akanakisa magetsi conductor 

Nheyo dzesainzi uye mashandiro ekutenderwa muGrathi Electrodes

Griray, crystalline yekubvuma kabhoni, inozivikanwa nekuda kwesimba remagetsi risingaenzaniswi kunyangwe kuve asiri simbi. Iyi nzvimbo yakasarudzika inomuka kubva kune yayo yakasarudzika atomu chimiro, yakafemerwa emagetsi maitiro, uye zvakanyanya Anisotropic crystalline gadziriro. Izvi zvinongedzo zvinoita graphite zvakaringana mukushandisa maindasitiri-kunyanya mune graphite electrodes inoshandiswa kune yemagetsi arc chira (eaf) nzeve uye metallurical kunatswa.

Atomic chimiro: Hexagonil yakarongedzwa lattice

Grafiti ine maatomu maatomu akarongwa mune maviri-emukati Hexagonil latties, iyo inowedzera kusingagumi muA-B ndege. Imwe neimwe kabhoni atomu inoumba matatu akasimba σ (Sigma) Cavelent zvisungo nevavakidzani varo, zvichikonzera kugadzikana grapheni marata nehurefu hwenzvimbo dzinosvika 1.42 å. Izvi zviyero zvakasungwa pamwe neC-axis, inobatwa pamwe neye isina kusimba van der waals masimba emauto, ine yakanganisa chinhambwe che 3.35

Imwe neimwe kabhoni tambakona ine magetsi mana: Vatatu vanotora chikamu mu σ Bonds, uye chechina vanogara p_Z orbital perpendicular kune ndege. Iyo yakazotevera inodarika yeiyi orbbitals inogadzira yakawedzerwa π (pi) electron gore, akashatiswa pamusoro peiyo yakazara layer.

Delocalized π-Electron Cloud: Iyo hwaro hweKukwikwidza Kubata

Iko kudenha kwe π ele ele ele ele ele ele ele. Kana munda wekunze emagetsi unoiswa, aya ma elekitori anotama nekuparadzira mashoma kuparadzira, zvichikonzera mukati-ma-ndege kubatana uye kusadzivirira kwemagetsi.

Symmetry uye kufanana kweiyo hexagonal latice inoderedza kuparadzira nekuwedzera kusimuka kwemagetsi, yakafanana neinowanikwa mune mamwe mitezo.

Interlayer Magetsi Concitivity: Limited asi Akakosha

Kunyangwe magetsi ekufambisa ari kumusoro mukati mezvirongwa, graphite anoratidzawo kushaya simba asi akakosha kunze-kwe-ye-ndege yekuita. Izvi zvinokonzerwa neQuentum tunneling uye inowedzera kufararira, iyo inogonesa nhamba shoma yemagetsi kushandurwa pakati pevakawirirana pasi. Ichi chiitiko chinobatsira kuti zviitwe zvitatu zviviri-zviyero zvekuita, kunyangwe zvichiramba zvakanyanya anistropic-ne-mu-ndege yekuita kunge ingangoita kakawanda kupfuura-ndege yekuita.

Yakaderera electron-phonon coupling: yakawedzera kushanda kweiyo yakakwirira kupisa

Grafiti inoratidza yakaderera Electron-phonon coupling, zvichireva kuti kuwirirana kwakapindirana nemagetsi emagetsi emagetsi uye lattice vibrations ndeye mashoma. Izvi zvinoguma zvakaderedzwa kutakura kupaza uye kuchengeta mashandiro emagetsi kunyangwe kupisa kwakakwirira. Yakasanganiswa neyakatanga interret polting point (> 3600 ° C) uye makemikari kugadzikana, graphite yakakodzera kune yakakwirira-yekudzidzira maitiro ekugadzirisa.

Graphite Electrodes: Technical Contsation uye maindasitiri ekushandisa

Zvivakwa zveGriray zvakasarudzika zvinoita kuti zvive zvinyorwa zvemagetsi emagetsi ekugadzira magetsi anoshandiswa mukati:

1.Elelectric arc machira (EAF) yekutanga steelmakaking

2.ladle zvivakwa (lf) yekondari metallurgy uye kunatsa

3.Vitimi

4.Bruses mune magetsi motors uye generactors inobudirira kuendesa ikozvino kuendesa

5.Eleleltorlytic cellin kugadzirwa kweAluminium, magnesium, uye chlorine

6.high-tembiricha midziyo, croctibles, uye nyukireya moderators

Mhedziso

Graphite's inoshamisa maitiro ndeye mhedzisiro yekuita kwayo π-electron network mukati mekusimbira griphene marita. Izvi, zvakasanganiswa neAnisotropic kuitwa, kudzikisira kwemari, uye kurasikirwa kwesimba kwakaderera, seti graphifite kunze kubva kune isinganyanyo kusiri-simbi uye kunyange mamwe mitezo. Izvi zvivakwa pasi pehunhu hwayo mumasito
