graphitehe allotrope o kalapona, he ʻeleʻele hina, paʻa paʻa me nā waiwai kemika paʻa a me ka pale ʻana i ka corrosion.ʻAʻole hiki ke maʻalahi me nā waikawa, alkalis, a me nā mea ʻē aʻe, a he mau mea maikaʻi e like me ke kūpaʻa wela kiʻekiʻe, conductivity, lubrication, plasticity, a me ke kūpaʻa haʻalulu wela.
No laila, hoʻohana pinepine ʻia no:
1.Refractory mea: Graphite a me kāna mau huahana i nā waiwai o ke kiʻekiʻe wela kū'ē a me ka ikaika, a ua nui hoʻohana 'ia i loko o ka metallurgical 'oihana e hana graphite crucibles.I ka hana kila, hoʻohana mau ʻia ka graphite ma ke ʻano he mea pale no nā mea kila a ma ke ʻano he lining no nā kapuahi metallurgical.
2.Conductive mea: hoʻohana 'ia i loko o ka uila 'oihana e hana electrodes, brushes, kalapona koʻokoʻo, kalapona paipu, maikaʻi electrodes no ka mercury maikaʻi transformers o kēia manawa, graphite gaskets, kelepona'āpana, uhi no ke kīwī paipu, etc.
ʻO 3.Graphite he kūpaʻa kemika maikaʻi, a ma hope o ka hana kūikawā, loaʻa iā ia nā hiʻohiʻona o ka pale ʻana i ka corrosion, maikaʻi thermal conductivity, a me ka haʻahaʻa permeability.Hoʻohana nui ʻia ia i ka hana ʻana o nā mea hoʻololi wela, nā pahu hopena, nā condensers, nā hale kiaʻi ahi, nā hale kiaʻi absorption, nā mea hoʻomaʻamaʻa, nā mea hoʻomehana, nā kānana, a me nā lako pahū.Hoʻohana nui ʻia i nā ʻāpana ʻoihana e like me ka petrochemical, hydrometallurgy, acid-base production, synthetic fibers, a me ka hana pepa.
4.Making hoolei ana, one huli, molding, a me ke kiʻekiʻe-mehana metallurgical mea: Ma muli o ka liʻiliʻi thermal hoʻonui coefficient o graphite a me kona hiki ke ku i ka hoʻololi 'ana i ka wikiwiki hooluolu a me ka wela, hiki ke hoʻohana 'ia e like me ka poni no aniani.Ma hope o ka hoʻohana ʻana i ka graphite, hiki i ka metala ʻeleʻele ke loaʻa i nā ana hoʻoheheʻe pololei, ʻoluʻolu ʻili kiʻekiʻe, a me nā hua kiʻekiʻe.Hiki ke hoʻohana ʻia me ka ʻole o ka hana ʻana a i ʻole ka hana liʻiliʻi, pēlā e mālama ai i ka nui o ka metala.
5. ʻO ka hana ʻana i nā ʻāpana paʻa a me nā kaʻina hana metallurgy pauka e hoʻohana maʻamau i ka hoʻohana ʻana i nā mea graphite e hana i nā waʻa seramika no ke kaomi ʻana a me ka sintering.ʻAʻole hiki ke hoʻokaʻawale ʻia ka hana ʻana i nā crucibles ulu kristal, nā ipu hoʻomaʻemaʻe kūloko, nā mea kākoʻo, nā mea hoʻomehana induction, etc.Eia kekahi, hiki ke hoʻohana ʻia ka graphite ma ke ʻano he mea hoʻokaʻawale graphite a me ke kumu no ka hoʻoheheʻe ʻana i ka vacuum, a me nā ʻāpana e like me ke kiʻekiʻe kiʻekiʻe o ka pale ʻana i ka umu ahi, nā koʻokoʻo, nā papa, a me nā grids.
