Indasitiri, girafu yechisikigo inoiswa mucrystalline graphite uye cryptocrystalline graphite zvinoenderana nekristaro fomu. Iyo crystalline graphite iri nani yakakwenenzverwa, uye dhayamita yekristaro ndeye> 1 μm, iyo inonyanya kugadzirwa nekristaro imwe chete kana kristaro inoputika. Crystalline graphite chimwe chezvicherwa makumi maviri nemana zviri munyika. Kuongorora nekuvandudzwa kwegraphite kwakanyorwa muNational Mineral Resources Planning (2016-2020) kekutanga. Kukosha kwecrystalline graphite kunotungamirirwa nemafungiro akadai semotokari itsva dzemagetsi uye graphene. Kuwedzera kukuru.
Maererano neUS Geological Survey (USGS), kusvika pakupera kwe2017, nzvimbo dzepasi rose dzegirafu dzinenge mamiriyoni mazana maviri nemakumi manomwe ematani, anonyanya kuparadzirwa muTurkey, China neBrazil, iyo China inotungamirirwa necrystalline graphite uye Turkey inonzi cryptocrystalline graphite. Iyo cryptocrystalline graphite ine yakaderera kukosha uye kushoma budiriro uye tarisiro yekushandisa, saka crystalline graphite inosarudza pasi rose graphite pateni.
Sekureva kweChinese Academy yeSainzi, China crystalline graphite inodarika 70% yepasi rose. Pakati pavo, Heilongjiang Province's crystalline graphite zviwanikwa zvinogona kuverengera makumi matanhatu muzana eChina uye anopfuura makumi mana muzana epasirese, ayo anoita basa rekuita. Nyika dzinogadzira crystalline graphite iChina, ichiteverwa neIndia neBrazil.

process status
Madhipoziti ekuChina ane magiredhi akanaka emaindasitiri, ayo akanaka kumigodhi, uye giredhi recrystalline graphite harisi pasi pe3%. Mumakore gumi apfuura, China inobuda pagore yegraphite iri pakati pe60,000 ne800,000 matani, iyo crystalline graphite kugadzirwa inoita 80%.
Kune anopfuura chiuru echiuru mabhizinesi ekugadzira magirafu muChina, uye zvigadzirwa zve graphite zvicherwa zvigadzirwa zvakaita sepakati uye yakakwira kabhoni graphite, yakakwirira kuchena graphite uye yakanaka poda graphite, pamwe nekuwedzera graphite uye kabhoni zvinhu. Chimiro chebhizinesi chinonyanya kufambiswa nehurumende, iyo inonyanya kugoverwa muShandong, Inner Mongolia, Hubei, Heilongjiang, Zhejiang nedzimwe nzvimbo. Bhizinesi rehurumende rekuchera magirafu rine hwaro hwakasimba uye mabhenefiti akakosha mune tekinoroji nezviwanikwa.
Graphite inoshandiswa zvakanyanya musimbi, metallurgy, foundry, mechanical equipment, indasitiri yemakemikari nemamwe minda nekuda kwehunhu hwayo hwakanaka. Nekufambira mberi kwesainzi uye tekinoroji, kugona kwekushandisa kwezvinhu zvitsva zvegraphite mumaindasitiri epamusoro-soro senge simba idzva, indasitiri yenyukireya, ruzivo rwemagetsi, aerospace uye dziviriro iri kuongororwa zvishoma nezvishoma, uye inoonekwa senzira yehunyanzvi inodiwa kuvandudzwa kwemaindasitiri ari kusimukira. Parizvino, zvigadzirwa zveChina zvegraphite zvinonyanya kushandiswa muzvinhu zvinoramba, castings, zvisimbiso, yakakosha graphite nemimwe minda, pakati peiyo refractory zvinhu uye castings inonyanya kushandiswa.
Nekuenderera mberi kwekusimudzira kweindasitiri yesimba idzva, kudiwa kwegraphite mune ramangwana kucharamba kuchiwedzera.
