ʻO ka mea nui o ke daimana he kalapona, ʻo ia ka mineral i haku ʻia me nā mea kalapona.He allotrope ia o ka graphite me kahi ʻano kemika o C, ʻo ia hoʻi ke kino kumu o nā daimana maʻamau.ʻO ka daimana ka mea paʻakikī loa i hana maoli ʻia ma ke ʻano.He mau kala like ʻole ka daimana, mai ka ʻeleʻele a i ʻeleʻele.Hiki iā lākou ke aniani, translucent a opaque paha.ʻO ka hapa nui o nā daimana he melemele, ʻo ia ka mea ma muli o nā haumia i loko o nā daimana.He kiʻekiʻe loa ka papa kuhikuhi refractive o daimana, a he ikaika loa ka hana hoʻopuehu, ʻo ia ke kumu e hōʻike ai ke daimana i nā uila ʻulaʻula.E hoʻopuka ʻo Diamond i ka ʻulaʻula uliuli-'ōmaʻomaʻo ma lalo o ka hoʻomālamalama X-ray.
ʻO nā daimana ko lākou mau pōhaku maoli, a ua lawe ʻia nā daimana ma nā wahi ʻē aʻe e nā muliwai a me nā glaciers.ʻO ka daimana maʻamau ka granular.Inā wela ke daimana i 1000°C, e huli mālie ia i graphite.I ka makahiki 1977, ua ʻike kekahi kamaʻāina ma Changlin, Sushan Township, Linshu County, Shandong Province, i ka daimana nui loa o Kina ma ka honua.Hoʻopuka ʻia nā daimana ʻoihana nui loa o ka honua a me nā daimana momona ma ʻApelika Hema, ʻoi aku ma mua o 3,100 carats (1 carat = 200 mg).He 10 × 6.5 × 5 cm ka nui o nā daimana a kapa ʻia ʻo "Cullinan".I ka makahiki 1950, ua hoʻohana ʻo ʻAmelika i ka graphite ma ke ʻano he mea maka no ka hana ʻana i nā daimana synthetic ma lalo o ke kiʻekiʻe o ka wela a me ke kaomi.I kēia manawa ua hoʻohana nui ʻia nā daimana synthetic i ka hana a me ke ola o kēlā me kēia lā.
ʻO ke kumu kemika o ke daimana c.ʻO ke ʻano aniani o daimana ka nui octahedron, rhombic dodecahedron, tetrahedron a me kā lākou hui.Inā ʻaʻohe haumia, ʻaʻohe waihoʻoluʻu a ʻākala.I ka hana ʻana me ka oxygen, e hoʻopuka pū ʻo ia i ke kalapona kalapona, nona ka carbon elemental like me ka graphite.He 109 ° 28 ' ka huina pili o ke aniani daimana, he mau waiwai kino maikaʻi loa ia e like me superhard, wear-resistant, thermal sensitivity, thermal conductivity, semiconductor and far transmission.Uaʻikeʻiaʻo iaʻo "ke aliʻi o ka paʻakikī" a me ke aliʻi o nā pōhaku makamae.ʻO ka huina o ke aniani daimana he 54 degere 44 minuke 8 kekona.ʻO ka mea maʻamau, kāhea pinepine ka poʻe i ka daimana i hana ʻia a me ka daimana i hana ʻole ʻia.Ma Kina, ua ʻike mua ʻia ka inoa daimana ma nā palapala hemolele Buddhist.ʻO ka daimana ka mea paʻakikī loa ma ke ʻano.ʻO ka waihoʻoluʻu maikaʻi loa he kala ʻole, akā aia kekahi mau kala kūikawā, e like me ka uliuli, ka poni, ka melemele gula, a pēlā aku.ʻO India ka ʻāina hana daimana kaulana loa ma ka mōʻaukala.I kēia manawa he nui nā daimana kaulana i ka honua, e like me "mauna o ka mālamalama", "Regent" a me "Orlov", mai India mai.He kakaikahi ka hana daimana.ʻO ka mea maʻamau, ʻo ka daimana i hoʻopau ʻia he hoʻokahi piliona piliona o ka nui o ka mining, no laila ke kumukūʻai nui loa.Ma hope o ka ʻoki ʻana, he poepoe nā daimana, ʻehā, ʻehā, oval, ʻano puʻuwai, ʻano pea, ʻoliva kiko, a pēlā aku. ʻO ka daimana kaumaha loa ma ka honua ʻo "curinan" i hana ʻia ma ʻApelika Hema i ka makahiki 1905. He 3106.3 carats a ua loaʻa. lepo i 9 mau daimana liilii.ʻO kekahi o lākou, ʻo curinan 1, i kapa ʻia ʻo "African star", ke kūlana mua nei i ka honua.
Nui ka hoʻohana ʻana o nā daimana.E like me kā lākou hoʻohana ʻana, hiki ke hoʻokaʻawale ʻia nā daimana i ʻelua mau ʻāpana: gem-grade (decoration) daimana a me nā daimana ʻoihana.
Hoʻohana nui ʻia nā daimana maʻamau no nā mea nani e like me nā apo daimana, nā lei, nā apo pepeiao, nā corsages, a me nā mea kūikawā e like me nā lei aliʻi a me nā koʻokoʻo, a me ka hōʻiliʻili ʻana i nā pōhaku ʻala.Wahi a nā helu helu, helu ʻia nā kālepa daimana ma kahi o 80% o ka nui o ke kālepa waiwai makahiki ma ka honua.
Ke hoʻohana nui ʻia nei nā daimana ʻoihana ʻoihana, me ka paʻakikī kiʻekiʻe a me ke kūpaʻa maikaʻi ʻana i ka lole, a hiki ke hoʻohana nui ʻia i ka ʻokiʻoki, wili, a me ka wili;Hoʻohana ʻia ka pauka daimana ma ke ʻano he mea abrasive kiʻekiʻe.
ʻo kahi laʻana:
1. Hana i nā mea hana abrasive resin bond a i ʻolemea wiliwili, etc.
2. Hana ʻiaMetala Daimana Mea wili, mea paahana ceramic bond abrasive tools or grinding tools, etc.
3. Ka hana ʻana i nā ʻāpana hoʻoheheʻe honua stratum maʻamau, semiconductor a me nā mea non-metallic e ʻoki ana i nā mea hana, etc.
4. Ka hana ʻana i nā ʻāpana hoʻoheheʻe honua paʻakikī, nā mea hana hoʻoponopono a me nā mea hana paʻa ʻole a me nā mea hana ʻino, etc.
5. ʻO nā pad poni daimana resin, nā mea hana abrasive paʻa ceramic a wili paha, etc.
6. Nā mea hana abrasive paʻa metala a me nā huahana electroplated.ʻO nā mea hana wili a wili paha, etc.
7. ʻO ka ʻeli, ka ʻeli ʻana a me ka hoʻoponopono ʻana, etc.
Eia kekahi, ua hoʻohana nui ʻia i ka ʻoihana koa a me ka ʻenehana ākea.
Me ka ulu wikiwiki o ka ʻepekema a me ka ʻenehana a me ka ʻoihana hou, e ʻoi aku ka nui o ka hoʻohana ʻana i ka daimana, a ʻoi aku ka nui o ka nui.Kakaikahi loa na waiwai daimana maoli.ʻO ka hoʻoikaika ʻana i ka hana a me ka noiʻi ʻepekema o ke daimana synthetic ka pahuhopu o nā ʻāina āpau o ka honua.ʻekahi.
