Hoʻohana nui ʻia ka flake graphite i ka ʻoihana, nona nā ʻano ponoʻī kiʻekiʻe. I kēia lā, e haʻi aku ʻo Furuite Graphite Xiaobian iā ʻoe i nā kumu no nā ʻano kiʻekiʻe o ka flake graphite mai nā ʻano o nā mea hoʻohuihui ʻohana a me nā kristal i hui pū ʻia:
ʻO ka mea mua, nā ʻano kiʻekiʻe o nā mea kalapona e hana anagrafita ʻāpana.
1. Kūpaʻa loa nā ʻano kemika o ke kalapona elemental i ka mahana o ka lumi, a he mea hoʻoheheʻe ʻole ia i ka wai, ka waikawa dilute, ka alkali dilute a me nā mea hoʻoheheʻe organik;
2, e pane ana me ka oxygen ma nā mahana kiʻekiʻe like ʻole e hana i ke kalapona dioxide a i ʻole ke kalapona monoxide; I loko o ka halogen, ʻo ka fluorine wale nō ke pane pololei me ke kalapona elemental;
3. Ma lalo o ka hoʻomehana ʻana, ua maʻalahi ka oxidized o ke kalapona elemental e ka waikawa;
4. I ke ana wela kiʻekiʻe, hiki i ke kalapona ke hana pū me nā metala he nui e hana i nā carbides metala;
5. Kalaponahiki ke hoʻemi ʻia a hiki ke hoʻohana ʻia e hoʻoheheʻe i nā metala ma ke ana wela kiʻekiʻe.
ʻO ka lua, nā ʻano o nā kristal i hui ʻia i haku ʻia me ka graphite flake.
1. I loko o ke kristal graphite, hoʻohuihui nā ʻātoma kalapona ma ka papa like me sp2 e hana i nā pilina covalent, a ua hoʻopili ʻia kēlā me kēia ʻātoma kalapona me ʻekolu mau ʻātoma ʻē aʻe e ʻekolu mau pilina covalent. ʻEono mau ʻātoma kalapona e hana i kahi apo hexagonal ma ka mokulele like, e kīkoʻo ana i loko o kahi ʻano papa, kahi o ka lōʻihi o ka pilina o ka pilina CC he 142pm āpau, nona ka laulā lōʻihi o ka pilina o ke kristal atomika, no laila no ka papa like, he kristal atomika ia.
2. Ua hoʻokaʻawale ʻia nā papa o nā kristal graphite e 340pm, he mamao loa ia, a ua hui pū ʻia e ka ikaika van der Waals, ʻo ia hoʻi, no nā kristal molekala nā papa. Eia nō naʻe, ma muli o ka pilina ikaika ma waena o nā ʻātoma kalapona ma ka papa mokulele like, he mea paʻakikī loa ia e luku aku, no laila ke kiko heheʻe ografitihe kiʻekiʻe nō hoʻi a paʻa kona mau waiwai kemika.
