ʻO ka pāpaʻi Graphite he conductivity uila maikaʻi, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka waikawa, ka pale ʻana i ka corrosion alkali, ka hana maʻalahi. No laila, hoʻohana nui ʻia i ka metallurgy, ʻoihana kemika, electrochemistry a me nā ʻoihana ʻē aʻe. ʻO kekahi o ka hoʻohana nui ʻana i nā papa graphite ma ka semiconductor field, akā hoʻohana nui ʻia i nā cell solar, sensors, nanoelectronics, high-performance nanoelectronic device, composite material, field emission material a me nā māla ʻē aʻe.
Loaʻa ka hopena anti-radiation a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻokaʻawale wela. Aia nā ʻano ʻelua o nā papa graphite: ka maʻemaʻe kiʻekiʻe a me nā papa graphite metala. Hoʻokumu ʻia ka mea hope me kahi pā metala kumu a me kahi wili graphite maʻalahi, a he ʻelua ʻano o ka perforated a i hoʻopaʻa ʻia. Hiki iā ia ke paʻi i nā ʻano gaskets āpau a he mea hoʻopaʻa paʻa me ka laulā noi ākea a me ka hana hoʻopaʻa paʻa ikaika.
Hoʻohana nui ʻia nā papa graphite i ka ʻoihana. Hiki ke hoʻohana ʻia i ka hana ʻana i ke kīʻaha wela kiʻekiʻe no ka hoʻoheheʻe ʻana, ka mea pale no ka ingot kila, ka lubricant no ka ʻoihana mechanical, electrode a me ke alakaʻi penikala. ʻO nā mea refractory a me nā uhi no ka ʻoihana metallurgical, pyrotechnic material stabilizers no ka ʻoihana koa, penikala alakaʻi no ka ʻoihana māmā, carbon brushes no ka ʻoihana uila, electrodes no ka ʻoihana pākaukau, catalysts no ka ʻoihana fertilizer, etc. kū'ē! Ma keʻano laulā, ʻoi aku ka kiʻekiʻe o nā koi no ka pale ʻana i ka oxidation i ke kaʻina hana o ka pā graphite, ʻoi aku ka nui o ka hoʻohana ʻia ʻana ma ke ʻano he papa insulation pā, pono e loaʻa i nā pono o ka pale ʻana o ka oxidation, i ʻoi aku ka maikaʻi o nā pono. Me he mea lā e ʻoi aku ka kiʻekiʻe o nā koi ʻenehana, a hōʻike ʻia ka pono hana i ke kaʻina o ka hoʻohālikelike.
Ke hoʻomau nei ke ola lawelawe o ka pā graphite, a ua hoʻonui nui ʻia ke ola o nā mea kahiko. Ua hōʻike ʻia nā hoʻokolohua he nui hiki ke hiki i 30-50 mau makahiki. Ma kēia mea, pono nō e hoʻomaopopo i nā pono ʻenehana a me nā ʻano. Ma hope o ka hoʻopaʻa ʻana i ke āpau, pono ia e hōʻoia i ka wā e hoʻohana ʻia ai i ka ʻoihana.
