Ihe kpatara njirimara dị elu nke graphite flake

A na-ejikarị graphite flake eme ihe na ụlọ ọrụ, nke sitere na njirimara ya dị elu. Taa, Furuite Graphite Xiaobian ga-agwa gị ihe kpatara njirimara dị elu nke flake graphite sitere na akụkụ nke ihe mejupụtara ezinụlọ na kristal agwakọta:

anyi

Nke mbụ, njirimara dị elu nke ihe ndị na-emepụta carbon na-emegraphite flake.

1. The chemical Njirimara nke elemental carbon bụ dịtụ kwụsiri ike na ụlọ okpomọkụ, na ọ bụ insoluble na mmiri, itughari acid, itughari alkali na organic solvents;

2, na-emeghachi omume na oxygen na okpomọkụ dị elu dị iche iche iji mepụta carbon dioxide ma ọ bụ carbon monoxide; Na halogen, naanị fluorine nwere ike ime ozugbo na carbon elemental;

3. N'okpuru kpo oku, elemental carbon na-adị mfe oxidized site acid;

4. N'ebe okpomọkụ dị elu, carbon nwekwara ike meghachi omume na ọtụtụ ọla iji mepụta carbide metal;

5. Carbonbụ reducible na a pụrụ iji gbaze ọla na elu okpomọkụ.

Nke abuo, njirimara nke kristal agwakọtara nke graphite flake mejupụtara.

1. Na graphite crystal, carbon atom n'otu oyi akwa hybridize na sp2 na-etolite covalent agbụ, na onye ọ bụla carbon atom na-jikọrọ na atọ ọzọ atọ ndị ọzọ atọ covalent agbụ. Atọm carbon isii na-etolite mgbanaka hexagonal n'otu ụgbọ elu ahụ, na-agbatị n'ime usoro dị larịị, ebe njikọ ogologo nke CC bond bụ 142pm niile, nke bụ nke njikọ ogologo nke kristal kristal, yabụ maka otu oyi akwa, ọ bụ atọm. kristal.

2. A na-ekewa akwa nke kristal graphite site na 340pm, nke bụ ebe dị anya, ma jikọta ya site na ike van der Waals, ya bụ, akwa akwa bụ kristal molecular. Otú ọ dị, n'ihi na njikọ siri ike n'etiti carbon atom n'otu ụgbọ elu oyi akwa, ọ bụ nnọọ ike ibibi, otú ahụ agbaze ebe.eseresedịkwa elu na chemical Njirimara ya kwụsiri ike.
