He ʻano kumuwaiwai mineral ka pauka graphitepaukame ka hoʻohuihui koʻikoʻi. ʻO kāna ʻāpana nui he kalapona maʻalahi, he palupalu, hina ʻeleʻele a me ka momona. ʻO kona paʻakikī he 1 ~ 2, a piʻi aʻe i 3 ~ 5 me ka hoʻonui ʻia o ka ʻike haumia ma ke kuhikuhi kū pololei, a ʻo kona kaumaha kikoʻī he 1.9 ~ 2.3 Ma lalo o ke kūlana o ka hoʻokaʻawale ʻana i ka ea a me ka oxygen, ʻoi aku kona kiko heheʻe ma luna o 3000 ℃, ʻo ia kekahi o nā kumuwaiwai mineral pale wela.
Ma ka mahana o ka lumi, ʻo ke ʻano loiloi o ka ʻike kemika, ka hoʻonohonoho ʻana a me nā waiwai opauka grafitiHe ʻōnaehana a paʻa hoʻi, a he mea hoʻoheheʻe ʻole ia i ka wai, ka waikawa dilute, ka alkali dilute a me ka mea hoʻoheheʻe organik. Loaʻa i ka hana noiʻi o ka ʻepekema mea hana kekahi hana palekana o ka pūnaewele conductive composite pale wela kiʻekiʻe, hiki ke hoʻohana ʻia ma ke ʻano he mea nui no ka hoʻolālā pale ahi, nā mea hana conductive a me nā mea loea lubrication pale ʻaʻahu.
Ma nā mahana kiʻekiʻe like ʻole, pane ia me ka oxygen e hana i nākalaponaʻO ka dioxide a i ʻole ke kalapona monoxide. Ma waena o ke kalapona, ʻo ka fluorine wale nō ke hiki ke hana pololei me ke kalapona elemental. Ke hoʻomehana ʻia, ʻoi aku ka maʻalahi o ka oxidize ʻana o ka pauka graphite e ka waikawa. I ke ana wela kiʻekiʻe, hiki i ka pauka graphite ke hana me nā metala he nui e hana i nā carbides metala, a hiki ke hoʻoheheʻe ʻia nā metala i ke ana wela kiʻekiʻe.
He mea hopena kemika koʻikoʻi loa ka pauka graphite, a e loli kona kūpaʻa ma lalo o nā kūlana like ʻole.Pauka graphiteHe mea hoʻokele metala maikaʻi loa ia. Inā mālama ʻia ka pauka graphite i loko o nā mea hoʻokaʻawale, e hoʻopiʻi ʻia ia e like me ka uea lahilahi, akā ʻaʻole pololei ka helu kūʻē. No ka mea, ʻokoʻa ka mānoanoa o ka pauka graphite, e loli pū ka waiwai kūʻē o ka pauka graphite me ka ʻokoʻa o nā mea a me ke kaiapuni.
