diamondi yokulirapo masiku ano imapangidwa pogwiritsa ntchito njira ziwiri - CVD ndi HPHT.Kulenga kwathunthu kumatenga nthawi yosakwana mwezi umodzi.Kumbali ina, chilengedwe cha diamondi chachilengedwe pansi pa kutumphuka kwa Dziko lapansi chimatenga mabiliyoni azaka.

Njira ya HPHT imagwiritsa ntchito imodzi mwa njira zitatu zopangira izi - makina osindikizira lamba, makina a cubic press ndi split-sphere press.Njira zitatuzi zitha kupangitsa kuti pakhale kutentha kwambiri komanso kutentha komwe diamondi imatha kukula.Zimayamba ndi njere ya diamondi yomwe imayika mu carbon.Daimondiyo imayikidwa pa 1500 ° Selsiasi ndikukanikizidwa mpaka mapaundi 1.5 pa inchi imodzi.Pomaliza, mpweya umasungunuka ndipo diamondi ya labotale imapangidwa.

CVD imagwiritsa ntchito njere yopyapyala ya diamondi, yomwe nthawi zambiri imapangidwa pogwiritsa ntchito njira ya HPHT.Daimondiyo imayikidwa m’chipinda chotenthedwa kufika pafupifupi 800 ° C chomwe chimakhala ndi mpweya wochuluka wa carbon, monga Methane.Kenako mipweyayo imalowa mu plasma.Mpweya woyera wochokera ku mipweya umamatira ku diamondi ndikuwunikiridwa.
