- Ki sa ki se Lab Grown Diamond
Diferans ki genyen ant yon dyaman natirèl ak yon laboratwa grandi soti nan fason yo te fè.Laboratwa grandi Diamonds yo fè moun nan yon laboratwa pandan y ap kawo natirèl yo kreye sou tè a.
Premye siksè dyaman sentetik yo te fè pa mimicking nati ak segondè presyon / segondè tanperati (HPHT) manifakti.Gen twa pwosesis fabrikasyon debaz yo itilize pou fè dyaman HPHT: laprès senti, laprès kib, ak laprès fann-esfè (BARS).Objektif chak pwosesis se kreye yon anviwònman presyon ak tanperati ki wo anpil kote kwasans dyaman ka rive.Chak pwosesis kòmanse ak yon ti grenn dyaman ki mete nan kabòn epi mete anba presyon trè wo ak tanperati pou grandi dyaman an.
Yon lòt metòd popilè pou grandi diamnd sentetik se depo chimik vapè (CVD).Kwasans lan fèt anba presyon ki ba (anba presyon atmosferik).Li enplike nan manje yon melanj de gaz (tipikman 1 a 99 metàn nan idwojèn) nan yon chamver epi divize yo nan radikal chimik aktif nan yon plasma limen pa mikwo ond, filaman cho, arcdischarge, flanbo soude oswa lazè.Metòd sa a se sitou itilize pou kouch, men li ka pwodwi tou kristal sèl plizyè milimèt nan gwosè.
