Ko te kauwhata ngawari me te kauwhata tawerewere e rua nga ahua o te kauwhata, a ko nga ahuatanga hangarau o te kauwhata e whakawhirinaki ana ki te ahua o te kirikiri. Ko nga kohuke graphite me nga momo karaihe rereke he rereke nga uara ahumahi me nga whakamahinga. He aha te rereketanga o te kauwhata ngawari me te kauwhata tawerewere? Ka hoatu e te Etita Furuite Graphite he kupu whakataki taipitopito:
1. Ko te graphite ngawari te ahua o te hua graphite parakore teitei i hangaia mai i te graphite tawerewere na roto i te maimoatanga matū motuhake me te maimoatanga wera, kaore he here me nga poke, a he nui atu i te 99%. Hangaia te kauwhata hangore ma te pehi i nga matūriki kauwhata rite noke ki raro i te pehanga kore rawa. Karekau he hanganga karaihe graphite rite tonu, engari he mea hanga na te whakaemi kore-aronga o te maha o nga katote kauwhata kua whakaritea, no te hanganga polycrystalline. No reira, ka kiia ano te kauwhata ngawari he kauwhata whakawhanui, he kauwhata whakawhanui, he kauwhata ahua noke ranei.
2. Ko te kohatu ngawari te ahua o te kauwhata tawerewere whanui. He maha nga ahuatanga motuhake o te kauwhata ngawari ma te hangarau tukatuka motuhake. Ko te graphite ngawari he pai te pumau o te waiariki, te iti o te whakarea roha raina, te kaha o te rauropi me te aukati matū, te pai o te hiri hau-wai, te whakahinuhinu-whaiaro me nga taonga miihini pai rawa atu, penei i te ngawari, te mahi, te compressibility, te resilience me te kirihou.
Āhuatanga,-whakatika i te aukati kōpeketanga me te hōhonutanga tensile me te mau parenga, etc.
3. Ko te kauwhata ngawari e kore e pupuri noa i nga ahuatanga o te kauwhata tawerewere, engari he haumaru me te kore paitini. He nui te waahanga mata motuhake me te mahi mata teitei, a ka taea te pehi me te hanga me te kore he whakamaarama teitei me te taapiri i te here. Ka taea te hanga kauwhata hangore hei pepa pepa graphite ngawari, whakakai whakakai kauwhata ngawari, peera maru kowiri tira, tauira kowakawaka kauwhata ngawari me etahi atu waahanga hiri miihini. ngawari
Ka taea hoki te hanga graphite hei pereti maitai, etahi atu waahanga ranei.
