Qhov txawv ntawm cov pob zeb diamond thiab hluavtaws pob zeb
- May 08, 2018 -

1, xim:

Synthetic diamonds feem ntau yog tan, thiab feem ntau yog irradiated los ntawm xiav, txiv kab ntxwv, liab dawb, xim av, thiab xim daj.

98% ntawm ntuj diamonds yog tsis muaj xim tsis pom xim daj.

2, kev siv lead ua:

Synthetic diamonds yog feem ntau: ntsuas, octahedrons, thiab ob qho tib si

Cov pob zeb diamonds feem ntau yog octahedrons, rhombic dodecahedrons, thiab polycondensation ntawm ob qho tib si, thiab zoo li ntau daim duab thaij-yeeb yaj duab ob kiv.

3, zoom saib:

Synthetic diamond: noob siv lead ua thiab nws lub phantom thaj tsam, ntau hom hlau inclusions

Ntuj pob zeb: tsis muaj cov hlau pob zeb

4, qhov ntxhib ntxoo thiab sab hauv:

Khoom siv pob zeb diamond: tuaj yeem tso saib dendritic lossis khaub lig zoo li kev ntxhib los mos

Pob zeb diamond: Lub nplhaib ntawm daim duab peb sab los sis daim duab peb sab, sab nraud feem ntau qhia txog kev ntxhib los mos ntsig txog tus qauv.

5, UV fluorescence:

Synthetic diamond Synthetic diamond: Nyob rau hauv ntev yoj, feem ntau nws tsis yog fluorescent. Nyob rau hauv luv luv yoj, nws muaj daj-ntsuab, txiv kab ntxwv-daj fluorescence, muaj "Maltese cross zoning" phenomenon, thiab muaj tseeb phosphorescence.

Pob zeb diamond: Nws yog xim xiav-dawb fluorescence nyob rau hauv ntev nthwv dej, qaug zog nyob rau hauv luv luv yoj los yog inert.

6, pom lub teeb pom kev zoo:

Synthetic diamonds: Tsis muaj 415.5nm nqus dej, qhov nqes dej ntawm 658nm thiab tag nro nqes dej qis dua 500nm tuaj yeem ntsuas raws li cov huab cua uas tsis muaj feem tau los ntawm kua nitrogen.

Pob zeb diamond: Feem ntau ntawm lawv yog 415.5nm nqus dej

7, UV fluorescence:

Cov pob zeb diamond: Feem ntau nws tsis yog fluorescent nyob ntev ntev, daj-ntsuab, txiv kab ntxwv daj-fluorescence nyob rau hauv luv luv yoj, "Maltese cross zoning" phenomenon, thiab pom tseeb phosphorescence

Pob zeb diamond: Nws yog xim xiav-dawb fluorescence nyob rau hauv ntev nthwv dej, qaug zog nyob rau hauv luv luv yoj los yog inert.

8. Cathodometer:

Synthetic diamond: zoo ib yam li cov yam ntxwv ntawm cov hluav taws xob uas muaj ultraviolet fluorescence, cov cheeb tsam sib txawv sib txawv qhia tias fluorescence bands

Ntuj diamonds: Feem ntau cov lus Vim tias lub pob zeb diamond hlob zoo, ib puag ncig hloov ntawm lub sijhawm mus rau lub sijhawm, tab sis cov pob zeb diamond loj hlob ib puag ncig yog ib yam zoo li qub.

9, infrared spectroscopy:

Khoomtuab Pob Zeb Diamond: Absorption ntawm 1130 nqaj

Ntuj Pob Zeb Ntawd: Cov Nruab Nrab ntawm 1176, 1282 Beams
