Graphite – A Versatile Mineral

(Graphite – A Versatile Mineral)

Graphite ine zvakawanda zvakasiyana-siyana, zvinongoitika zvega mineral inoumbwa ne pure carbon. Inocherwa pasi rose kusanganisira China, India, Shiri Ranga, Brazil uye North Korea.

Flake graphite inogadzirwa kana kabhoni inoiswa mukupisa kwakanyanya uye kudzvanywa kunokonzerwa nemetamorphic maitiro akadai seregional metamorphism muEarth crust uye pamusoro pejasi.. Iyo kabhoni inoumba hexagonal mitsara yezvikamu zvakabatanidzwa pamwe neakasimba covalent zvisungo zvine husimba hweVan der Waals kupindirana.. Aya maumbirwo anoita kuti graphite igadzikane zvakanyanya uye inokwanisa kubata nhamba huru yemaerekitironi yakatevedzana. Ichi chivakwa chinoita kuti ive yakanakira lubrication uye magetsi conductivity.

Graphite inogona kucherwa setsinga, seams kana flake. Iyo yekupedzisira ndiyo inonyanya kufarirwa yegraphite inotengeswa uye inouya mune mana akasiyana saizi: jumbo flake, hombe huru, medium flake uye fine flake. Inowanzo kuchena kupfuura amorphous graphite uye kazhinji inodhura zvakanyanya sezvo iine mamwe mashandisiro. Kuchena kunobva kumativi 80% ku 99.9+%.

Amorphous graphite inowanzoshandiswa serefractory, kuumba uye kukanda zvinhu. Inoshandiswawo muindasitiri yesimbi seyakasimudza kabhoni. Pamusoro pezvo inowanikwa mumabhureki linings uye clutch zvinhu pamwe nepenzura lead. Penzura inotungamira inowanzogadzirwa kubva kune yakaderera mhando amorphous graphite.

Mutengi mukuru wezvakasikwa amorphous graphite ndiyo indasitiri yemotokari. Electric, hybrid uye mafuta emotokari mota dzese dzinoda flake graphite sechinhu chakakosha mumabhatiri avo. Kusvika nguva pfupi yadarika amorphous graphite kugadzirwa kwakanangana neChina uko 75-80% zvepasi rese zvinocherwa. Zvinetso zvekutengesa zvine chekuita neChina zvakatungamira kuEuropean Union kusanganisira graphite pane rondedzero ye 14 "yakakosha zvigadzirwa" izvo zvinogona kutarisana nenjodzi dzekupa.
