Qhov sib txawv ntawm CVD thiab HPHT Laboratory Grown Pob Zeb

Koj tsis tuaj yeem paub qhov txawv ntawm cov kab ntsuas tsim cov gems nrog lub qhov muag liab qab. Ob txoj kev tuaj yeem tsim cov pob zeb diamond zoo nkauj thiab ci ntsa iab. Lub ntsiab sib txawv ntawm HPHT pob zeb diamond thiab CVD pob zeb diamonds hauv lawv cov yam ntxwv ntawm kev loj hlob.
Yog tias kuaj xyuas kom zoo nrog lub khob iav, kws kho pob zeb tau pom sib txawv ntawm kev saib cov qauv crystal.

Zog:
Kev lig kev cai, HPHT cov pob zeb diamond tsim ntau cov xim, tab sis vim yog cov txheej txheem thev naus laus zis, ob cov tswv yim tuaj yeem tsim cov pob zeb diamond tam sim no. HPHT Diamonds muaj 14 txoj kev nthuav dav kev nthuav dav thiab cubic octahedral, thaum CVD pob zeb diamond muaj cov qauv lus qub thiab txoj kev loj hlob. Yog li ntawd, CVD pob zeb diamond qee zaus ua piv txwv ntawm cov qauv stramped.
Vim tias qhov tseeb tias CVD pob zeb diamond tau tsim txheej txheej los ntawm txheej txheej tsis sib xws ntawm cov khaubncaws sab nraud povtseg ntawm cov khaubncaws sab nraud povtseg, ua rau cov pob zeb diamond tshwm sim hauv cov ntsej muag. Txawm li cas los xij, qhov no yog qhov tshwm sim tsawg uas tuaj yeem pom hauv qab lub khob tsom iav.
Cov tuam txhab tsim tau pom tias cov khoom lag luam nyob hauv qhov kub thiab txias tuaj yeem tshem tawm cov xim av, ua rau muaj xim tsis muaj xim. Cov txheej txheem no yog hu ua kev kub siab thiab muaj kev siab siab siab.

Cov Khoom Sib Nqus:
Hlau flux suav nrog yog cov xeeb ceem uas muaj ntau ntawm cov kub thiab cov pob zeb diamond high-maint. Cov impurities no tshwm sim dub nyob rau hauv kev sib kis lub teeb, tab sis muaj nws yog xim hlau luster. Lawv lub neej yog vim yog hlau catalysts thaum lub sijhawm txhim kho Crystal.
Cov suav no muaj cov kab sib txuas xws li npib tsib xee, hlau, thiab cobalt. Lawv lub peev xwm tuaj yeem tso cai rau cov hlau nplaum txhawm rau ntes cov pob zeb kuaj ua pob zeb uas muaj ntau cov hlau impurities.
CVD pob zeb diamond tsis muaj cov xim hlau suav nrog. Ntawm qhov tsis sib xws, nws cov txheej txheem tsim tshwj xeeb ua nyob rau hauv muaj cov graphite graphite inclusions.

Nqi:
Xav txog lub zog hluav taws xob uas yuav tsum tau thiab khoom siv HPHT yog kim heev. CVD pob zeb diamond yog tus nqi ntau dua vim tias lawv cov txheej txheem tsim khoom yog nqa tawm ntawm qhov kub thiab txias thiab cov kev ntsuas tsis tau. Lawv kuj yuav tsum muaj cov khoom siv uas pheej yig dua.
