SI1-SI2 B Grade HPHT Man Made Diamond Stone Kanggo Jewels
- Apa Lab Grown Diamond
Bedane antarane berlian alami lan lab sing ditanam saka berlian saka cara digawe.Berlian sing ditanam ing laboratorium digawe ing laboratorium, dene inten alami digawe ing bumi.
Berlian sintetis pisanan sing sukses digawe kanthi niru alam kanthi manufaktur High Pressure/High Temperature (HPHT).Ana telung proses manufaktur dhasar sing digunakake kanggo nggawe berlian HPHT: pers sabuk, pers kubik, lan pers split-sphere (BARS).Tujuan saben proses yaiku nggawe lingkungan tekanan lan suhu sing dhuwur banget ing ngendi pertumbuhan berlian bisa kedadeyan.Saben proses diwiwiti kanthi wiji berlian cilik sing diselehake ing karbon lan dilebokake ing tekanan lan suhu sing dhuwur banget kanggo tuwuh berlian kasebut.
Cara populer liyane kanggo ngembangake diamnd sintetik yaiku deposisi uap kimia (CVD).Wutah kasebut dumadi ing tekanan sing sithik (ing ngisor tekanan atmosfer).Iki kalebu nyedhot campuran gas (biasane 1 nganti 99 metana dadi hidrogen) menyang chamver lan dibagi dadi radikal aktif kimia ing plasma sing diobong dening gelombang mikro, filamen panas, busur, obor las utawa laser.Cara iki biasane digunakake kanggo lapisan, nanging uga bisa ngasilake kristal siji ukuran sawetara milimeter.
