Dab tsi yog cov chemistry qab graphite electrodes thiab nws cuam tshuam li cas rau lawv kev ua tau zoo?

The chemistry behind graphite electrodes centers on the ​​unique properties of carbon in its crystalline form-graphite​​-which is the result of a highly controlled manufacturing process involving ​​carbonization and graphitization​​ of organic compounds like ​​petroleum coke​​ and ​​coal tar pitch​​. Graphite muaj ib tug fawm hexagonal lathatic atoms yog sib raug zoo nyob rau hauv ob {{} qhov dav dav dav hlau tab sis ntau dua xoob ntawm cov dav hlau. Qhov no muab graphite nws zoo hluav taws xob thiab thermal siv nyob rau hauv cov dav hlau, siab thermal cov khoom siv hluav taws xob, thiab anisotropic neeg kho tshuab.

From a chemical perspective, the ​​purity of carbon​​ is critical. High-quality graphite electrodes are composed of ​​>99% Carbon, nrog tsawg heev ntawm kev tsis txaus ntseeg xws li leej faj, cov rog, lossis cov hlau hnyav, lossis paug, tshwj xeeb yog cov khoom siv stative thiab sib xyaw. Kev impurities tuaj yeem ua rau hluav taws xob tsis kam, txo qis kev ua haujlwm.
