He kiʻekiʻe loa ke alakaʻi wela a me ke alakaʻi uila o nā koʻokoʻo graphite, a ʻo ko lākou alakaʻi uila he 4 mau manawa kiʻekiʻe ma mua o ke kila kila, 2 mau manawa kiʻekiʻe ma mua o ke kila kalapona, a 100 mau manawa kiʻekiʻe ma mua o nā mea ʻole metala maʻamau. ʻAʻole wale kona alakaʻi wela ma mua o ke kila, ka hao, ke kēpau a me nā mea metala ʻē aʻe, akā e emi ana hoʻi me ka piʻi ʻana o ka mahana, kahi ʻokoʻa mai nā mea metala maʻamau. I nā mahana kiʻekiʻe loa, hiki i ka graphite ke wela. No laila, hilinaʻi loa nā waiwai insulation wela o ka graphite i nā mahana kiʻekiʻe loa.
Hoʻohana pinepine ʻia nā koʻokoʻo graphite no ka unuhi electrothermal i loko o nā umu hoʻoheheʻe wela kiʻekiʻe. Hiki i ka mahana hana kiʻekiʻe ke piʻi i 3000℃, a he mea maʻalahi ke hoʻoheheʻe ʻia i nā mahana kiʻekiʻe. Koe wale nō ka vacuum, hiki ke hoʻohana ʻia i nā lewa kūlike ʻole a hoʻemi paha.
Ma muli o kona mau waiwai maikaʻi loa, hoʻohana nui ʻia ka graphite ma nā ʻano like ʻole a hiki ke hoʻohana ʻia e like me kahi mea refractory.
Mālama nā huahana graphite i nā waiwai kemika mua o ka graphite flake a he mau waiwai lubrication ponoʻī ikaika. Hōʻike ʻia ka pauka graphite e ka ikaika kiʻekiʻe, ke kūpaʻa waikawa, ke kūpaʻa corrosion, ke kūpaʻa wela kiʻekiʻe a me ka haʻahaʻa.
He kūpaʻa kemika maikaʻi ko Graphite i ka mahana o ka lumi a ʻaʻole ia e pala i kekahi waikawa ikaika, kumu ikaika a me ka mea hoʻoheheʻe organik, no laila inā hoʻohana ʻia no ka manawa lōʻihi, he liʻiliʻi loa ka nalowale o nā huahana graphite, inā e holoi ʻia, ua like ia me ka mea hou.
