Isizathu se-electrolysis yenduku ye-graphite

Izimo zokwakha iseli le-electrolytic: Ukunikezwa kwamandla e-DC. (1) Ukunikezwa kwamandla e-DC. (2) Ama-electrode amabili. Ama-electrode amabili axhunywe epalini elihle lokunikezwa kwamandla. Phakathi kwawo, i-electrode elihle elixhunywe epalini elihle lokunikezwa kwamandla libizwa ngokuthi i-anode, kanti i-electrode exhunywe epalini elihle lokunikezwa kwamandla libizwa ngokuthi i-cathode. (3) Isixazululo se-Electrolyte noma i-electrolyte encibilikisiwe.I-Electrolyteisixazululo noma isixazululo 4, ama-electrode amabili kanye nokusabela kwe-electrode, i-anode (exhunywe ensikeni enhle yokunikezwa kwamandla): i-oxidation reaction anode (exhunywe ensikeni enhle yokunikezwa kwamandla): i-oxidation reaction cathode (exhunywe ensikeni embi yokunikezwa kwamandla): i-reduction reaction cathode (exhunywe ensikeni embi yokunikezwa kwamandla): i-reduction reaction cathode (exhunywe ensikeni embi yokunikezwa kwamandla): i-reduction reaction cathode (exhunywe ensikeni embi yokunikezwa kwamandla): i-reduction reaction (i-electrode engemihle exhunyiwe): i-reduction group 1: i-electrolysis group 1: i-electrolysis ye-CuCl2 anode cathode chlorine.
     I-Graphiteiyikristalu yekhabhoni. Kuyinto engeyona eyensimbi enombala ompunga wesiliva, ithambile futhi icwebezela ngensimbi. Ubulukhuni be-Mohs bungu-1-2, amandla adonsela phansi athile angu-2.2-2.3, kanti ubukhulu bayo ngokuvamile bungu-1.5-1.8.
Indawo yokuncibilika kwe-graphite iqala ukuthamba uma ifika ku-3000 ℃ ku-vacuum futhi ivame ukuncibilika. Uma ifika ku-3600 ℃, i-graphite iqala ukuhwamuka futhi incibilike. Amandla ezinto ezijwayelekile ancipha kancane kancane ekushiseni okuphezulu, kuyilapho amandla e-graphite ephindwe kabili kunalawo ekushiseni kwegumbi uma ishiswa ku-2000 ℃. Kodwa-ke, ukumelana kwe-oxidation kwe-graphite kubi, futhi izinga le-oxidation liyakhula kancane kancane ngokukhuphuka kwezinga lokushisa.
Iukuhanjiswa kokushisakanye nokuguquguquka kwe-graphite kuphakeme impela. Ukuguquguquka kwayo kuphakeme ngokuphindwe kane kunensimbi engagqwali, kuphakeme ngokuphindwe kabili kunensimbi yekhabhoni futhi kuphakeme ngokuphindwe kayi-100 kunensimbi evamile engeyona eyensimbi. Ukuguquguquka kwayo kokushisa akudluli nje kuphela okwezinto zensimbi ezifana nensimbi, insimbi kanye nomthofu, kodwa futhi kwehla ngokukhuphuka kwezinga lokushisa, okuhlukile ezintweni zensimbi ezijwayelekile. I-Graphite ivame nokuba yi-adiabatic emazingeni okushisa ahlukene. Ngakho-ke, ukusebenza kokushisa kwe-graphite kuthembekile kakhulu ekushiseni okuphezulu.
I-Graphite inamafutha amahle kanye ne-plasticity. I-coefficient yokungqubuzana kwe-graphite ingaphansi kuka-0.1. I-Graphite ingathuthukiswa ibe amashidi angaphefumulwa futhi asobala. Ubulukhuni be-graphite enamandla aphezulu bukhulu kangangokuthi kunzima ukuyicubungula ngamathuluzi edayimane.
I-Graphite inokuqina kwamakhemikhali, i-asidi kanyeukumelana ne-alkalikanye nokumelana nokugqwala kwe-organic solvent. Ngenxa yokuthi i-graphite inezakhiwo ezinhle kakhulu ezingenhla, isetshenziswa kabanzi embonini yanamuhla.
