I. Halayen Tsarin Lu'ulu'u
Tsarin Layi: Tsarin lu'ulu'u na coke mai siffar graphitized ya ƙunshi hanyoyin sadarwa na planar na atom ɗin carbon mai siffar hexagonal. Waɗannan hanyoyin sadarwa na planar an tara su a layi ɗaya, suna samar da tsari na yau da kullun mai layi ɗaya. Ana haɗa layukan ta hanyar ƙarfin van der Waals mai rauni, wanda ke ba da graphite mai laushi da anisotropy.
Ma'aunin Lattice: Bayan an yi amfani da graphitization, ma'aunin lattice (a₀ da c₀) na petroleum coke sun kusanci na graphite na halitta, wanda ke nuna babban kamanceceniya a cikin tsarin lu'ulu'unsu. Wannan fasalin tsarin yana bawa petroleum coke mai graphitized damar nuna kyakkyawan yanayin wutar lantarki da zafi.
Sigogi na Microcrystalline: Ta amfani da diffraction na X-ray, ana iya ƙididdige sigogi kamar tazara tsakanin layukan (d₀₀₂), matsakaicin diamita na Layer (Lₐ), da tsayin stacking (Lc) na microcrystals a cikin graphitized petroleum coke. Waɗannan sigogi suna nuna girma da tsarin microcrystals kuma suna aiki azaman mahimman alamomi don kimanta matakin graphitization.
II. Tasirin Tsarin Zane-zane
Sauyawa daga Amorphous zuwa Crystalline State: Kafin a yi amfani da graphitization, tsarin carbon na petroleum coke ba shi da tsari, wanda ke da siffa ta "tsawon lokaci mai rikitarwa, mai tsari na ɗan gajeren lokaci". Ta hanyar maganin graphitization (yawanci ana yin sa a yanayin zafi mai yawa daga 2500°C zuwa 3000°C), carbon mai amorphous yana canzawa a hankali zuwa tsarin graphite mai girma uku.
Ƙara Girman Microcrystallite: A lokacin graphitization, matsakaicin kauri (Lc) da faɗi (Lₐ) na flakes na carbon suna ƙaruwa, yayin da tazara tsakanin layukan (d) ke raguwa. Wannan yana haifar da ƙaruwa a girman microcrystallite da kuma tsarin lu'ulu'u mafi kyau.
Rage Juriya: Yayin da matakin graphitization ke ƙaruwa, juriyar coke mai siffar graphitized yana raguwa sosai. Wannan saboda, yayin graphitization, tsarin ƙwayoyin carbon yana ƙara tsari, yana ba da damar electrons su motsa cikin 'yanci a cikin matakan Layer, ta haka ne ke haɓaka ikon lantarki.
III. Alaƙa Tsakanin Tsarin Ƙwayoyin Halitta da Halaye
Tsarin wutar lantarki: Tsarin lu'ulu'u mai layi-layi na coke mai siffar petroleum yana bawa electrons damar motsawa cikin tsari mai kyau, wanda ke haifar da kyakkyawan yanayin wutar lantarki. Wannan siffa ta sa coke mai siffar petroleum ya zama mai amfani sosai a fannoni kamar kayan lantarki da ƙari mai sarrafa wutar lantarki.
Tsarin Gudanar da Zafi: Saboda ƙarfin van der Waals da ke haɗa layukan, ana iya canja wurin zafi cikin sauri a cikin layukan layukan. Saboda haka, coke ɗin petroleum mai graphitized shima yana nuna kyakkyawan yanayin zafi, wanda hakan ya sa ya dace da ƙera kayan watsa zafi da sauran aikace-aikace.
Halayen Inji: Tsarin lu'ulu'u na coke mai siffar graphitized yana ba shi wani ƙarfin inji. Duk da haka, idan aka kwatanta da kayan ƙarfe, tsarinsa mai layi yana haifar da rauni a cikin layukan da ke haɗuwa, wanda ke haifar da ƙarancin ƙarfin lanƙwasa da matsewa. Wannan halayyar aiki yana ba coke mai siffar graphitized fa'ida a cikin yanayi inda yake buƙatar jure wasu matsin lamba amma ba ya buƙatar ƙarfi mai yawa.
