Graphite ntụ ntụ bụ ihe na-enwe mmetụta nke ukwuu maka mmeghachi omume kemịkal.N'ebe dị iche iche, nkwụsị ya ga-agbanwe, nke pụtara na uru nkwụsị ya ga-agbanwe.Otú ọ dị, e nwere otu ihe na-adịghị agbanwe agbanwe.Graphite ntụ ntụ bụ otu n'ime ezigbo ihe ndị na-eduzi ihe na-adịghị mma.Ọ bụrụhaala na a na-edobe ntụ ntụ graphite n'akwụsịghị akwụsị n'ime ihe mkpuchi, ọ ga-enwekwa ọkụ dị ka waya dị mkpa.Otú ọ dị, ọ dịghị ọnụ ọgụgụ ziri ezi maka uru nkwụsị, N'ihi na ọkpụrụkpụ nke ntụ ntụ graphite dịgasị iche, uru nkwụsị nke ntụ ntụ graphite ga-adịkwa iche mgbe ejiri ihe dị iche iche na gburugburu ebe obibi.N'ihi nhazi ya pụrụ iche, graphite nwere ihe ndị a pụrụ iche:

1) Ụdị na-eguzogide okpomọkụ dị elu: ebe na-agbaze nke graphite bụ 3850 ± 50 ℃, ebe isi mmiri bụ 4250 ℃.Ọbụlagodi na agba ya ọkụ site na arc ultra high okpomọkụ, oke ibu na ọnụọgụ nke mgbasawanye thermal dị obere.Ike nke graphite na-abawanye na okpomọkụ, na 2000 ℃, ike nke graphite na-abawanye okpukpu abụọ.
2) Conductivity na thermal conductivity: The conductivity nke graphite bụ 100 ugboro elu karịa nke nkịtị na-abụghị ọla.Nrụgide okpomọkụ karịrị nke ihe igwe dị ka ígwè, ígwè, na lead.Okpomọkụ na-abawanye na okpomọkụ na-ebelata, na ọbụna na oke okpomọkụ, graphite na-aghọ ihe mkpuchi.
3) Lubricity: arụmọrụ lubrication nke graphite dabere na nha flakes graphite.Ka flakes ndị ahụ na-ebuwanye ibu, ọnụ ọgụgụ esemokwu na-adị ntakịrị, yana ịrụ ọrụ mmanye mmanye ka mma.
4) Nkwụsi ike nke kemịkalụ: graphite nwere ezigbo nkwụsi ike kemịkalụ na ụlọ okpomọkụ, ma nwee ike iguzogide acid, alkali na organic mgbaze corrosion.
5) Plasticity: Graphite nwere ezigbo ike ma nwee ike jikọọ ya na mpempe akwụkwọ dị gịrịgịrị.
6) Mgbochi ujo na-ekpo ọkụ: Graphite nwere ike iguzogide mgbanwe mgbanwe okpomọkụ na-enweghị mmebi mgbe ejiri ya na ụlọ okpomọkụ.Mgbe okpomọkụ na-agbanwe na mberede, olu nke graphite adịghị agbanwe nke ukwuu ma ọ gaghị agbawa.

1. Dị ka ihe refractory: graphite na ngwaahịa ya nwere njirimara nke nguzogide okpomọkụ dị elu na ike dị elu.Na ụlọ ọrụ ọla, a na-eji ya eme ihe nkedo graphite.N'ime nchara, a na-ejikarị graphite eme ihe dị ka ihe nchebe maka ingots ígwè na mkpuchi nke ọkụ ọla.
2. Dị ka ihe na-eduzi ihe: eji na ụlọ ọrụ eletrik na-emepụta electrodes, brushes, carbon ros, carbon tubes, nti electrodes maka mercury nti nke ugbu a transformers, graphite gaskets, ekwentị akụkụ, mkpuchi maka telivishọn tubes, wdg.
3. Dị ka ihe na-eme ka mmanu mmanu na-eyi: A na-ejikarị graphite eme ihe dị ka mmanụ mmanu na ụlọ ọrụ mmepụta ihe.Enweghị ike iji mmanụ lubricating mgbe mgbe n'okpuru nnukwu ọsọ, oke okpomọkụ na ọnọdụ nrụgide dị elu, ebe ihe ndị na-eguzogide graphite nwere ike ịrụ ọrụ na-enweghị mmanụ mmanụ na nnukwu ọsọ ọsọ na okpomọkụ sitere na 200 ruo 2000 ℃.Ọtụtụ ngwaọrụ ndị na-ebu mgbasa ozi na-emebi emebi bụ ihe graphite na-eme n'ọtụtụ ebe iji mee iko piston, mgbanaka akara, na bearings, nke na-adịghị achọ mgbakwunye mmanụ mmanye n'oge ọrụ.Emulsion graphite bụkwa ezigbo mmanye maka ọtụtụ nhazi ígwè (ịse waya, eserese tube).
