Ọla kọpa impregnated graphite bụ nke graphite na ọla kọpa ahụ mejupụtara. N'ime ha, graphite bụ ihe carbonaceous, nke nwere ike kewaa n'ime graphite eke na graphite artificial. Ụdị kristal nke graphite eke bụ mpempe akwụkwọ hexagonal, nke nwere nnukwu kristal na ịdị elu thermal conductivity. Ọ bụ ihe kacha mma thermal conductivity. The artificial graphite bụ tumadi akwadoro site elu-okpomọkụ sintering na ndị ọzọ usoro, na nwere àgwà nke ọma homogeneity na elu ike.
Ngwakọta ọla kọpa na-ejikọta ọla kọpa na graphite site na usoro a kapịrị ọnụ iji mepụta graphite ọla kọpa.

4. Sintering: na-eme ka akụkụ ndị a na-emepụta ihe na-emepụta ihe siri ike nke graphite ọla kọpa.
Isi njirimara nke graphite ọla kọpa bụ ndị a:
(1) Ezi conductivity: ọla kọpa impregnated graphite nwere ọtụtụ irighiri ọla kọpa, nke na-eme ka omume ya dị oke mma.
(2) Ezigbo ihe eji arụ ọrụ: ọnụnọ nke ọla kọpa na-eme ka ike na ike nke graphite dịkwuo mma, na-eme ka ọ nwee ihe ndị dị mma.
(3) Nguzogide dị mma: ọnụnọ nke ọla kọpa nwekwara ike imeziwanye nkwụsị nke graphite.
(4) Ezigbo nguzogide corrosion: graphite n'onwe ya nwere ezigbo nguzogide corrosion. Na mgbakwunye na ihe ọla kọpa, nguzogide corrosion ya dị oke mma.
(5) Ezi conductivity thermal: graphite bụ ihe dị mma na-ekpo ọkụ ọkụ. Mgbe agbakwunyere ahụ ọla kọpa, conductivity thermal ya ka mma.
graphite ọla kọpa nwere ihe nrụpụta dị mma na akụrụngwa akụrụngwa, a na-ejikwa ya na ngwa batrị, njikwa ọkụ, ngwaọrụ eletrọnịkị, nrụpụta igwe na mpaghara ndị ọzọ.
N'ihe gbasara ihe batrị, a na-eji graphite ọla kọpa mee ihe n'ọtụtụ ebe na nkwadebe nke efere electrode batrị iji meziwanye arụmọrụ nke batrị n'ihi àgwà ya dị mma na ihe eji arụ ọrụ.
