Cov tshuaj muaj pes tsawg leeg ntawm pob zeb diamond yog C, thiab graphite yog tib yam li carbon homogenous polymorphic variant. Nyob rau hauv cov ntxhia tshuaj muaj pes tsawg leeg, nws ib txwm muaj Si, Mg, Al, Ca, Mn, Ni thiab lwm yam, thiab feem ntau muaj Na, B, Cu, Fe, Co, Cr, Ti, N thiab lwm yam impurities, nrog rau cov carbohydrates. .
Cov qauv siv lead ua ntawm pob zeb diamond minerals belongs rau tetrahedral qauv ntawm isoaxial siv lead ua system. Cov pa roj carbon atoms nyob ntawm lub ces kaum apex thiab nruab nrab ntawm tetrahedron, uas muaj symmetry siab. Cov pa roj carbon atoms hauv chav tsev cell txuas nrog homopolar bonds ntawm qhov deb ntawm 154 teev. Cov duab siv lead ua feem ntau yog octahedron, rhomboid dodecahedron, lub voos xwmfab, tetrahedron thiab hexahedron, thiab lwm yam.
3. Kev ruaj ntseg thiab ruaj khov
. Pob zeb diamond siv lead ua zaj duab xis yog ib yam ntawm cov khoom siv dag zog ntawm cov khoom siv tshiab, nws yog tsim los ntawm micro siv lead ua pob zeb diamond, siab hardness, tsis tshua muaj kev sib txhuam, siab kub conductivity (5 zaug) rau tooj liab, tsis tshua muaj expansion coefficient, siab thermal shock kuj, zoo corrosion kuj, zoo hluav taws xob insulating zog, dav band, siab transmittance thiab siab electron refractive index composite kev ua tau zoo. Cov khoom no yog non-toxic.
.Cov xim ntawm pob zeb diamond nyob ntawm qhov degree ntawm purity, hom thiab cov ntsiab lus ntawm impurity ntsiab muaj nyob rau hauv nws. Pob zeb diamond ntshiab heev yog xim tsis muaj xim, feem ntau qhia txawv degrees ntawm daj, xim av, grey, ntsuab, xiav, milky dawb thiab ntshav, thiab lwm yam. Translucent los yog opaque nrog impurities; Nyob rau hauv lub cathode rays, X ray thiab ultraviolet rays, nws yuav emission txawv ntsuab, ntuj xiav, ntshav, daj-ntsuab thiab lwm yam xim ntawm fluorescence; Nyob rau hauv lub hnub tom qab raug rau chav tsaus nti plaub hau teeb xiav phosphorescence; Adamantine luster, ob peb greasy los yog xim hlau luster, nrog ib tug siab refractive index, feem ntau 2.40-2.48.
.Diamond tshuaj muaj zog ruaj khov, nrog rau cov kua qaub thiab alkali tsis kam, kub tsis cuam tshuam nrog cov concentrated HF, HCl, HNO3, tsuas yog nyob rau hauv lub cev molten ntawm Na2CO3, NaNO3, KNO3, los yog boil nrog cov sib tov ntawm K2Cr2O7 thiab H2SO4, qhov chaw. yuav oxidized me ntsis; Corrosion nyob rau hauv O, CO, CO2, H, Cl, H2O, CH4 high temperature gas.
