2. ʻIkepili Hoʻolālā Molecular
ʻO ka hui kemika o ke daimana C, a ʻo ka graphite ka like me ka carbon homogenous polymorphic variant. I loko o ka mineral chemical composition, loaʻa mau ʻo Si, Mg, Al, Ca, Mn, Ni a me nā mea ʻē aʻe, a loaʻa pinepine iā Na, B, Cu, Fe, Co, Cr, Ti, N a me nā mea haumia ʻē aʻe, a me nā mea momona. .
ʻO ke ʻano aniani o nā minerala daimana no ke ʻano tetrahedral o ka ʻōnaehana kristal isoaxial. Aia nā ʻātoma kalapona ma ke kihi kihi a me ke kikowaena o ka tetrahedron, nona ka symmetry kiʻekiʻe. Hoʻopili ʻia nā ʻātoma kalapona i loko o ke kelepona ʻāpana e nā paʻa homopolar ma kahi mamao o 154pm. ʻO nā ʻano aniani maʻamau he octahedron, rhomboid dodecahedron, cube, tetrahedron a me hexahedron, etc.
3. Prperties a me ka Pa'a
.Diamond kristal kiʻiʻoniʻoni mea he 'ano o artificial synthesis o hou functional mea, ua haku ia o micro aniani daimana, kiʻekiʻe paakiki, haʻahaʻa friction, kiʻekiʻe wela conductivity (5 manawa) no ke keleawe, haʻahaʻa hoʻonui coefficient, kiʻekiʻe thermal haʻalulu kū'ē, maikai corrosion. ke kū'ē, ka ikaika insulating uila maikaʻi, ka laulā ākea, ka transmittance kiʻekiʻe a me ka hana composite index refractive electron kiʻekiʻe. ʻAʻole ʻona kēia huahana.
ʻO ke kala o ke daimana e pili ana i ke kiʻekiʻe o ka maʻemaʻe, ke ʻano a me ka ʻike o nā mea haumia i loko. ʻAʻole waihoʻoluʻu ke daimana maʻemaʻe loa, e hōʻike ana i nā degere like ʻole o ka melemele, ʻeleʻele, hina, ʻōmaʻomaʻo, uliuli, waiu keʻokeʻo a me ka poni, etc. Translucent a opaque me nā haumia; Ma lalo o ke kukuna cathode, X ray a me ultraviolet ray, e hoʻopuka ʻo ia i nā ʻōmaʻomaʻo like ʻole, uliuli lani, poni, melemele-'ōmaʻomaʻo a me nā kala ʻē aʻe o ka fluorescence; I ka lā ma hope o ka ʻike ʻana i ka lauoho lumi ʻeleʻele phosphorescence uliuli; ʻO Adamantine luster, he liʻiliʻi hinuhinu a metala paha, me ka helu kuhikuhi refractive kiʻekiʻe, maʻamau 2.40-2.48.
.Diamond kemika waiwai paʻa, me ka waika a me ka alkali kū'ē, kiʻekiʻe wela 'aʻole e launa me ka concentrated HF, HCl, HNO3, wale i loko o ke kino hehee o Na2CO3, NaNO3, KNO3, a paila me ka hui o K2Cr2O7 a me H2SO4, ka ili. e oxidized iki; ʻO ka ʻino i loko o O, CO, CO2, H, Cl, H2O, CH4 kiʻekiʻe wela kinoea.
Nā noi
.Dimana no ka wili honua a me ka wili aila, daimana no ke kaha kii make, daimana no ka abrasives, daimana no ka lole, daimana no ka mea oki aniani, daimana no ka paakiki ana indenter, daimana no ka hana akamai.
.Hoʻohana ʻia ke daimana e hana i ke kiʻi daimana ma ka metala, ka plastic, ke aniani a me nā mea ʻē aʻe. E like me nā mea semiconductor a me nā mea semiconductor heat sink resistance, uila insulation layer.
.Ke aniani hoʻoponopono, PCD/PCBN, nā mea hana niho a me nā mea hana poʻo pōhaku
.Machining nonferrous mea like tungsten carbide, aniani a me nā ʻano mea like ʻole
ʻO ka hana pōhaku, ʻoihana kūkulu hale, no ka ʻeli ʻana, wili a me ka ʻeli ʻana i nā pōhaku, asphalt a me ke kaʻa...
