He kiʻekiʻe loa ka conductivity thermal a me ka conductivity uila o nā koʻokoʻo graphite, a ʻo kā lākou conductivity uila he 4 mau manawa kiʻekiʻe ma mua o ke kila kila, 2 mau manawa kiʻekiʻe ma mua o ke kila kalapona, a he 100 mau manawa kiʻekiʻe ma mua o nā metala maʻamau. ʻAʻole iʻoi aku ka nui o kāna conductivity thermal ma mua o ke kila, ka hao, ke alakaʻi a me nā mea metala ʻē aʻe, akā e emi pū me ka piʻi ʻana o ka mahana, ʻokoʻa ia mai nā mea metala maʻamau. Ma nā wela kiʻekiʻe loa, hiki ke wela ka graphite. No laila, hilinaʻi nui nā waiwai insulation thermal o ka graphite i nā mahana ultra-kiʻekiʻe.
Hoʻohana pinepine ʻia nā koʻokoʻo graphite no ka lawe ʻana i ka electrothermal i nā umu wela wela. Hiki ke piʻi ka mahana hana kiʻekiʻe i 3000℃, a he mea maʻalahi ke hoʻoheheʻe ʻia i nā wela kiʻekiʻe. Ma waho aʻe o ka vacuum, hiki ke hoʻohana wale ʻia i loko o nā lewa kūʻokoʻa a hoʻemi paha.
Ma muli o kāna mau waiwai maikaʻi, hoʻohana nui ʻia ka graphite ma nā ʻano āpau a hiki ke hoʻohana ʻia ma ke ʻano he mea refractory.
Mālama nā huahana graphite i nā waiwai kemika mua o ka flake graphite a loaʻa iā ia nā waiwai lubricating ikaika. Hōʻike ʻia ka pauka Graphite e ka ikaika kiʻekiʻe, ka pale ʻana i ka waikawa, ka pale ʻana i ka corrosion, ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa.
He paʻa kemika maikaʻi ka Graphite i ka wela o ka lumi a ʻaʻole ʻino ʻia e kekahi waikawa ikaika, kumu ikaika a me ka mea hoʻoheheʻe organik, no laila inā hoʻohana ʻia no ka manawa lōʻihi, liʻiliʻi loa ka nalowale o nā huahana graphite, ʻoiai e holoi ʻia. , ua like ia me ka mea hou.
