Okwu mmalite na ngwa nke Carbon (pyrolytic graphite) lekwasịrị anya

E kewara ebumnuche eserese ka ọ bụrụ graphite isostatic na graphite pyrolytic. Onye nchịkọta akụkọ RSM ga-ewebata graphite pyrolytic n'ụzọ zuru ezu.

Pyrolytic graphite bụ ụdị carbon ọhụrụ. Ọ bụ carbon pyrolytic nke nwere nghazi kristal dị elu nke etinyere site na uzuoku kemịkalụ na matrix graphite na 1800 ℃ ~ 2000 ℃ site na nnukwu ikuku hydrocarbon dị ọcha n'okpuru ụfọdụ nrụgide ọkụ. Ọ nwere nnukwu njupụta (2.20g / cm³), ịdị ọcha dị elu (ọdịnaya adịghị ọcha (0.0002%) na anisotropy nke thermal, eletriki, magnetik na nrụ ọrụ. Nke a pụtara na ọ nwere ihe dị iche iche n'ofe ụgbọ elu dị iche iche. Na ụgbọ elu C (n'ofe ya n'ígwé) ọ nwere obere okpomọkụ conductivity, na-eme dị ka ihe mkpuchi.
