2. Amakuru ku miterere ya molekile

Imiterere ya diyama ni C, naho grafiti ni kimwe n'ubwoko bwa polimorphic bwa karuboni. Mu miterere ya shimi ya diyama, ihora irimo Si, Mg, Al, Ca, Mn, Ni n'ibindi bintu, kandi akenshi irimo Na, B, Cu, Fe, Co, Cr, Ti, N n'indi myanda, ndetse na karubohidrati.

Imiterere ya kristu y'amabuye y'agaciro ya diyama igize imiterere ya tetrahedral ya sisitemu ya kristu ya isoaxial. Atome za karuboni ziherereye ku mfuruka no hagati ya tetrahedron, ifite uburinganire buhanitse. Atome za karuboni ziri mu karemangingo k'igice zihuzwa n'imigozi ya homopolar ku ntera ya saa sita n'iminota ine z'ijoro. Imiterere isanzwe ya kristu ni octahedron, rhomboid dodecahedron, cube, tetrahedron na hexahedron, nibindi.

Filimi ya kristale ya diyama ni ubwoko bw'ikorwa ry'ibikoresho bishya by'imikorere, igizwe na diyama ntoya, ubukana bwinshi, uburyaryate buke, ubushyuhe bwinshi (inshuro 5) ku muringa, ingano nto yo kwaguka, ubwiyongere bwinshi bw'ubushyuhe, ubwiyongere bwiza bw'ubushyuhe, imbaraga nziza zo gukingira amashanyarazi, umugozi munini, ubwiyongere bwinshi bw'itumanaho n'imikorere myinshi ya electron refractive index. Iki gicuruzwa ntikigira uburozi.

.Ibara rya diyama riterwa n'urwego rw'ubuziranenge, ubwoko n'ibikubiye mu bintu by'umwanda birimo. Diyama isukuye cyane nta ibara ifite, muri rusange igaragaza urwego rutandukanye rw'umuhondo, umukara, imvi, icyatsi kibisi, ubururu, umweru usa n'amata n'umuhengeri, nibindi. Irabagirana cyangwa ntigire icyo ihindura hamwe n'imyanda; Munsi y'imirasire ya cathode, imirasire ya X na ultraviolet, izatanga amabara atandukanye y'icyatsi kibisi, ubururu bwo mu kirere, umuhengeri, umuhondo-icyatsi n'andi mabara y'urumuri; Mu zuba nyuma yo guhura n'umusatsi wo mu cyumba cyijimye ufite phosphorescence y'ubururu bwerurutse; Adamantine luster, amavuta make cyangwa icyuma, ifite uburebure bwinshi bwo kugarura urumuri, muri rusange 2.40-2.48.

Imiterere ya diyama irahamye, hamwe n’ubudahangarwa bwa aside na alkali, ubushyuhe bwinshi ntibuhuza na HF, HCl, HNO3, gusa mu mubiri washongeshejwe wa Na2CO3, NaNO3, KNO3, cyangwa ukabira hamwe n’uruvange rwa K2Cr2O7 na H2SO4, ubuso buzahinduka oxidized gato; Kwangirika muri O, CO, CO2, H, Cl, H2O, CH4 gaze ifite ubushyuhe bwinshi.

Diyama yo gucukura imiterere y'ubutaka n'iy'ibikomoka kuri peteroli, diyama yo gushushanya, diyama yo gukata, diyama yo gukata ikirahure, diyama yo gukata icyuma, diyama yo gupima ubukana bw'ibipimo by'ubukorikori, diyama yo gushushanya ubukorikori n'ubukorikori.

Diyama ikoreshwa mu gukora filime ya diyama ku byuma, pulasitiki, ikirahure n'ibindi bikoresho. Nk'ibikoresho bya semiconductor na semiconductor birwanya ubushyuhe, urwego rwo gukingira amashanyarazi.

.Gutunganya ikirahure, PCD/PCBN, Ibikoresho by'amenyo n'ibikoresho byo gusiga amabuye

Gutunganya ibikoresho bidafite feri nka karubine ya tungsten, ikirahure n'ubwoko butandukanye bwa ceramics

Gutunganya amabuye, inganda z'ubwubatsi, gukata, gusya no gucukura amabuye, kaburimbo na sima...

Ubushyuhe bwinshi n'ubutabire buhamye

Ingufu nyinshi zo gukanda, igabanya ubushyuhe neza, irwanya ingese cyane, kandi ubushyuhe buragabanuka cyane.

Ubukomere bwinshi n'ubudahangarwa bwiza bwo kwangirika

Ubushyuhe bwinshi n'ubushyuhe bwiza bwo gukingira amashanyarazi

Itumanaho ry'urumuri ryiza cyane
