ʻO ka pauka Graphite kahi ʻano kumu waiwai mineralpaudame ka haku mele nui. ʻO kāna mea nui he kalapona maʻalahi, he palupalu, ʻeleʻele hina a momona. ʻO 1 ~ 2 kona paʻakikī, a piʻi aʻe i 3 ~ 5 me ka piʻi ʻana o ka ʻike haumia ma ke ala kū pololei, a ʻo kona umekaumaha kikoʻī ʻo 1.9 ~ 2.3 Ma lalo o ke kūlana o ka hoʻokaʻawale ʻana i ka ea a me ka oxygen, ʻoi aku kona wahi hoʻoheheʻe ma luna o 3000 ℃, ʻo ia kekahi o nā kumu waiwai mineral pale wela.
Ma ka lumi wela, ke ʻano analytical o ka ʻike kemika, ka hale a me nā waiwai ographite paudaʻano ʻōnaehana a paʻa, a ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai, dilute acid, dilute alkali a me ka mea hoʻoheheʻe organik. ʻO ka hana noiʻi o nā mea ʻepekema ʻenehana kekahi hana palekana o ka ʻenehana conductive composite kūpaʻa kiʻekiʻe, hiki ke hoʻohana ʻia ma ke ʻano he kumu nui no ka hoʻolālā ʻana i ke ahi, nā mea hana conductive a me nā mea ʻenehana lubrication pale ʻaʻahu.
Ma nā wela kiʻekiʻe like ʻole, hoʻopili ia me ka oxygen e hanakalaponadioxide a i ʻole carbon monoxide. Ma waena o ke kalapona, hiki i ka fluorine ke hana pololei me ke kalapona elemental. Ke hoʻomehana ʻia, ʻoi aku ka maʻalahi o ka pauka graphite e ka waika. I ka wela kiʻekiʻe, hiki i ka pauda graphite ke hana me nā metala he nui e hana i nā carbide metala, a hiki ke hoʻoheheʻe ʻia nā metala i ka wela kiʻekiʻe.
ʻO ka pauka Graphite kahi mea hoʻoheheʻe kemika koʻikoʻi, a e loli kona kū'ē ma lalo o nā kūlana like ʻole.ka pauda graphitehe mea maikaʻi maikaʻi ʻole metalaka conductive mea. ʻOiai ka lōʻihi o ka mālama ʻia ʻana o ka pauka graphite i loko o nā mea insulating, e hoʻopiʻi ʻia e like me kahi uea lahilahi, akā ʻaʻole helu pololei ka waiwai kū'ē. No ka mea ʻokoʻa ka mānoanoa o ka pauka graphite, e ʻokoʻa ke kūʻē ʻana o ka pauka graphite me ka ʻokoʻa o nā mea a me nā kaiapuni.
