SI1-SI2 B Qib HPHT Txiv Neej Ua Pob Zeb Diamond Rau Jewels
SI1-SI2 B Qib HPHT Txiv Neej Ua Pob Zeb Diamond Rau Jewels
- Dab tsi yog Lab Grown Pob Zeb Diamond
Qhov sib txawv ntawm ib lub ntuj thiab ib lub lab cog pob zeb diamond qia los ntawm qhov lawv tau ua.Lab cog pob zeb diamonds yog tib neeg tsim nyob rau hauv ib lub lab thaum lub ntuj pob zeb tsim nyob rau hauv lub ntiaj teb.
Thawj cov pob zeb zoo nkauj hluavtaws tau tsim los ntawm kev ua raws li qhov xwm txheej nrog High Pressure/High Temperature (HPHT) manufacturing.Muaj peb txoj hauv kev tsim khoom siv los ua HPHT pob zeb diamond: txoj siv xovxwm, qhov cubic xovxwm, thiab qhov sib cais-sphere (BARS) xovxwm.Lub hom phiaj ntawm txhua tus txheej txheem yog tsim kom muaj ib puag ncig ntawm kev kub siab thiab kub qhov twg pob zeb diamond loj tuaj yeem tshwm sim.Txhua txheej txheem pib nrog lub pob zeb diamond me me uas tau muab tso rau hauv cov pa roj carbon monoxide thiab muab tso rau hauv qhov kub thiab txias heev kom loj hlob pob zeb diamond.
Lwm txoj kev nrov ntawm kev loj hlob hluavtaws diamnd yog tshuaj vapor deposition (CVD).Kev loj hlob tshwm sim nyob rau hauv qis siab (hauv qab atmospheric siab).Nws koom nrog kev noj cov roj sib xyaw (feem ntau 1 txog 99 methane rau hydrogen) rau hauv lub chamver thiab faib lawv mus rau cov tshuaj lom neeg radicals hauv cov ntshav ignited los ntawm microwaves, kub filament, arcdischarge, vuam teeb lossis laser.Txoj kev no feem ntau yog siv rau txheej txheej, tab sis kuj tuaj yeem tsim ib qho crystals ob peb millimeters loj.
