Hoʻohana nui ʻia ka flake graphite i ka ʻoihana, i loaʻa mai kāna mau hiʻohiʻona kiʻekiʻe. I kēia lā, e haʻi aku ʻo Furuite Graphite Xiaobian iā ʻoe i nā kumu o nā hiʻohiʻona kiʻekiʻe o ka flake graphite mai nā ʻano o nā mea hoʻohui ʻohana a me nā kristal hui ʻia.
ʻO ka mea mua, nā hiʻohiʻona kiʻekiʻe o nā mea kalapona i hana ʻiagraphite liʻiliʻi.
1. ʻO nā waiwai kemika o ke kalapona elemental he paʻa ma ka lumi wela, a ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai, dilute acid, dilute alkali a me nā mea hoʻoheheʻe organik;
2, e pane ana me ka oxygen ma nā wela kiʻekiʻe like ʻole e hoʻohua i ke kalapona a i ʻole carbon monoxide; I loko o ka halogen, hiki i ka fluorine ke hana pololei me ke kalapona elemental;
3. Ma lalo o ka hoʻomehana ʻana, ua maʻalahi ke kalapona elemental e ka waikawa;
4. Ma ka wela kiʻekiʻe, hiki i ke kalapona ke hana pū me nā metala he nui e hana i nā carbide metala;
5. Kalaponahiki ke hoʻemi ʻia a hiki ke hoʻohana ʻia e honi i nā metala ma ke kiʻekiʻe wela.
ʻO ka lua, ʻo nā hiʻohiʻona o nā kristal hui ʻia i haku ʻia me ka flake graphite.
1. I loko o ka graphite crystal, hoʻohuihui nā ʻātoma kalapona i ka papa hoʻokahi me ka sp2 e hana i nā mea hoʻopaʻa covalent, a ua hoʻopili ʻia kēlā me kēia ʻātoma kalapona me ʻekolu mau ʻātoma ʻē aʻe e nā kaula covalent ʻekolu. Hoʻokumu ʻia nā ʻātoma kalapona ʻeono i apo hexagonal ma ka mokulele hoʻokahi, e hohola ana i loko o kahi ʻano papa, kahi o ka lōʻihi o ka paʻa o CC paʻa i ka 142pm, nona ka lōʻihi o ka lōʻihi pili o ka aniani atomika, no laila no ka papa like, he atomic ia. aniani.
2. Hoʻokaʻawale ʻia nā papa o nā kristal graphite e 340pm, kahi mamao loa, a ua hui pū ʻia e ka ikaika van der Waals, ʻo ia hoʻi, ʻo nā ʻāpana i nā kristal molecular. Eia naʻe, ma muli o ka paʻa paʻa ma waena o nā kalapona kalapona i ka papa mokulele hoʻokahi, paʻakikī loa ka luku ʻana, no laila ka helu heheʻe ographitekiʻekiʻe nō hoʻi a paʻa kona mau waiwai kemika.
