Kwimizi-mveliso, igraphite yendalo ihlelwa kwi-crystalline graphite kunye ne-cryptocrystalline graphite ngokwefomu yekristale. I-crystalline graphite iphuculwe ngcono, kwaye i-crystal plate diameter yi> 1 μm, eveliswa kakhulu yikristale enye okanye i-crystal flaky. Icrystalline graphite yenye yezimbiwa ezingama-24 ezicwangcisiweyo kweli lizwe. Ukuhlolwa nokuphuhliswa kwegraphite kudweliswe kuCwangciso lweMithombo yeziMbiwa kuZwelonke (2016-2020) okokuqala. Ukubaluleka kwe-crystalline graphite kukhokelwa yimiba efana neenqwelo zamandla amatsha kunye negraphene. Ukwanda okuphawulekayo.
Ngokutsho kwe-US Geological Survey (USGS), ekupheleni kuka-2017, iindawo zokugcina igraphite zehlabathi zimalunga ne-270 yezigidi zeetoni, ezisasazwa ikakhulu eTurkey, eChina naseBrazil, apho i-China ilawulwa yi-crystalline graphite kunye neTurkey yi-cryptocrystalline graphite. I-cryptocrystalline graphite inexabiso eliphantsi kunye nophuhliso olulinganiselweyo kunye nokusetyenziswa, ngoko ke i-crystalline graphite inquma ipateni yegraphite yehlabathi.
Ngokutsho kweAkhademi yaseTshayina yezeNzululwazi, igraphite yaseChina ithatha ngaphezu kwe-70% yetotali yehlabathi. Phakathi kwazo, izibonelelo zegraphite zePhondo laseHeilongjiang zingabalelwa kwi-60% yaseTshayina nangaphezulu kwe-40% yehlabathi, edlala indima ebalulekileyo. Abona bavelisi abakhulu becrystalline graphite yiTshayina, ilandelwa yiIndiya neBrazil.

Umyinge womgangatho wekhabhoni esisigxina kwi-graphite ore kwiindawo zasePanzhihua naseZhongba yi-6.21%. I-ore ubukhulu becala izikali ezincinci, kwaye isikali sesikali asikho ngaphezu kwe-0.15mm. Umgangatho wekhabhoni emiselweyo yekristale ye-ore yegraphite kwindawo yaseNanjiang kwiSixeko saseBazhong yi-5% ukuya kwi-7%, elona liphezulu li-13%, kwaye uninzi lwezikali zegraphite zi>0.15 mm. Umgangatho wekhabhoni esisigxina ye-graphite ore kwi-Aba Prefecture yi-5% ~ 10%, kunye nezikali ezininzi zegraphite <0.15mm.
IPhondo laseShanxi
IPhondo laseShanxi lifumene imithombo ye-8 yemithombo ye-crystalline echongiweyo yeeminerali ze-crystalline graphite, ezisasazwa kakhulu kwindawo yaseDatong. Umyinge womgangatho wekhabhoni esisigxina kwidiphozithi ubukhulu becala uphakathi kwe-3% kunye ne-4%, kwaye uninzi lwezikali zegraphite zi>0.15 mm. Uvavanyo lwentsimbi ekrwada lubonisa ukuba isivuno esikhulu esihambelanayo simalunga nama-38%, njengomgodi wegraphite kwilali yaseQili, kwiSithili saseXinrong, eDatong.
IPhondo laseShandong
Imithombo ye-crystalline graphite kwiPhondo laseShandong isasazwa ikakhulu eLaixi, ePingdu naseLaiyang. Ibakala eliqhelekileyo lekhabhoni esisigxina kwi-villa esezantsi-ntshona yeLai malunga ne-5.18%, kwaye ububanzi bamaphepha amaninzi egraphite buphakathi kwe-0.1 kunye ne-0.4 mm.

ubume benkqubo
Iidiphozithi zegraphite zaseTshayina zinamabakala amahle emizi-mveliso, alungele ukumbiwa kwemigodi, kwaye ibakala legraphite yecrystalline alikho ngaphantsi kwe-3%. Kule minyaka ili-10 idlulileyo, imveliso ye-graphite yase-China iphakathi kwama-60,000 kunye nama-800,000 eetoni, apho imveliso ye-crystalline graphite yenza malunga nama-80%.
Kukho ngaphezu kwewaka lamashishini okulungisa igraphite eTshayina, kwaye iimveliso ziimveliso zezimbiwa zegraphite ezinje ngegraphite ephakathi nephezulu, igraphite yococeko oluphezulu kunye nomgubo ocolekileyo wegraphite, kunye negraphite eyandisiweyo kunye necarbon materials. Ubume beshishini bulawulwa ngurhulumente ikakhulu, esasazwa kakhulu eShandong, eMongolia yangaphakathi, eHubei, eHeilongjiang, eZhejiang nakwezinye iindawo. Ishishini likarhulumente lemigodi yegraphite linesiseko esiluqilima kunye neenzuzo ezibalulekileyo kubuchwepheshe kunye nemithombo.
Igraphite isetyenziswa ngokubanzi kwintsimbi, isinyithi, isiseko, izixhobo zoomatshini, ishishini lemichiza kunye namanye amasimi ngenxa yeempawu zayo ezintle. Ngenkqubela phambili yenzululwazi kunye nobuchwepheshe, amandla okusetyenziswa kwezinto ezintsha zegraphite kumashishini obuchwepheshe obuphezulu njengamandla amatsha, ishishini lenyukliya, ulwazi lwe-elektroniki, i-aerospace kunye nokhuselo luyaphononongwa ngokuthe ngcembe, kwaye kuthathwa njengomthombo weqhinga oyimfuneko uphuhliso lwamashishini asakhasayo. Okwangoku, iimveliso zegraphite zaseTshayina zisetyenziswa kakhulu kwizinto eziphikisayo, ukuphoswa, izitywina, iigraphite ezikhethekileyo kunye neminye imimandla, phakathi kwazo izinto ezichasayo kunye nokuphosa zisetyenziswa kakhulu.
Ngophuhliso oluqhubekayo lweshishini elitsha lamandla, imfuno yegraphite kwixesha elizayo iya kuqhubeka ikhula.
Uqikelelo lwemfuno yegraphite yaseTshayina ngo-2020
