Ho latela Xinzhou Online, haufinyane tjena, projeke ea "High Purity Graphite Purification Key Technology Equipment and Application" e kopantsoeng ke Shanxi Zhongdian Electronic Equipment Co., Ltd. le China Minmetals e hapile khau ea pele ea Non Metallic Mineral Science and Technology ka 2025. Katleho ena e tšoaea hore China e hlōtse ka katleho bothata ba ho hloekisa le ho hloekisa tsamaiso ea {3} le bothata bo phahameng kgahleho.
High purity graphite ke "gauta e ntšo ea indasteri" mafapheng a bohlokoa a kang a sefofane le indasteri ea nyutlelie. Ntlafatso ya tshebetso e itshetlehile ka vacuum high-pheko ya ho hlwekisa mocheso, le{2}}maoto a ho hlwekisa mocheso o hodimo ke disebediswa tsa mantlha. Ka 2018, sehlopha sa lipatlisiso se ile sa qala katleho ea theknoloji ho rarolla bothata ba ho hloleha ho beha leihlo mocheso. Sehlopha se sebelisa tekhenoloji ea ho metha thempereichara e seng{6}}ea khokahanyo ho laola phoso ea tekanyo ea thempereichara ka har'a 1℃, e senyang bothata ba lisebelisoa tsa mantlha tse sa sebetseng ho 1800℃.
Ka mor'a moo, sehlopha se ile sa khetha lisebelisoa tse ncha tse hanyetsanang le mocheso-ho nolofalletsa lisebelisoa ho sebetsa ka mokhoa o tsitsitseng mochesong o sa fetoheng oa likhato tse 2400 nako e telele. E le ho arabela bothateng ba ho lumellana ha mocheso ka har'a sebōpi, sehlopha se ile sa sebelisa sebaka sa ho phalla ha moea le ho kopanya mocheso ho kopanya mokhoa oa ho etsisa mohlala. Ka mor'a liphetoho tse 17 mohahong oa sebōpi, lipapiso tse fetang 100 le litekanyo tsa sebele, sehlopha se atlehile ho finyella li-billet tse sa fetoheng tsa graphite ka har'a sebōpi tekong ea 22.
Sehlopha se boetse se hlotse phephetso ea tekheniki ea ho sebelisana lipakeng tsa mocheso o phahameng haholo-le mocheso o phahameng haholo, ho amohela moralo oa litsela tse peli tsa "pompa ka potlako" le "ho lutla ho fokolang", ho nolofalletsang lisebelisoa ho boloka tikoloho ea vacuum e phahameng ka likhato tse 2400 . Sehlahisoa se hloekisitsoeng ka thepa ena se na le molora o ka tlaase ho 1ppm, litšila tse ka sehloohong tse kang boron le aluminium content e ka tlaase ho 0.01ppm, bohloeki ba graphite ba 6.5N (99.99995%), le matšoao a bohlokoa a fihlang boemong bo phahameng ba machaba.
Qetellong ea 2019, sebōpi sa pele se ikemetseng sa ho hloekisa mocheso-ka holimo ho la China se ile sa kenngoa tšebetsong ka molao. Ka 2024, lisebelisoa li se li ntlafalitsoe ka litsamaiso tse bohlale tse ka nolofalletsang ho penya hanngoe tšebetsong eohle ea tlhahiso. Hajoale, Shanxi Zhongdian Technology e thehile sistimi e felletseng ea indasteri ho tloha lipatlisisong le nts'etsopele, tlhahiso ea liteko ho isa tlhahiso ea bongata. Palo e kholo ea libopi tsa tlhoekiso ea mocheso tse phahameng-e keneng ka har'a mekhoa ea tlhahiso ea lisebelisoa tse ncha tsa lehae le likhoebo tse ncha tsa matla (850101), tse tšehetsang ka matla polokeho le taolo e ikemetseng ea ketane ea indasteri ea thepa ea naha.
