- Kodi Lab Grown Diamond ndi chiyani
Kusiyana kwa diamondi yachilengedwe ndi labu yokulirapo kumachokera m'mene adapangidwira.Ma diamondi opangidwa ndi labu amapangidwa ndi anthu mu labu pomwe ma diamondi achilengedwe amapangidwa padziko lapansi.
Ma diamondi oyamba ochita bwino adapangidwa potengera chilengedwe popanga High Pressure/High Temperature (HPHT).Pali njira zitatu zopangira zopangira ma diamondi a HPHT: makina osindikizira a lamba, makina osindikizira a cubic, ndi a split-sphere (BARS).Cholinga cha ndondomeko iliyonse ndikupanga malo othamanga kwambiri komanso kutentha komwe kungachitike diamondi.Njira iliyonse imayamba ndi njere ya diamondi yaing'ono yomwe imayikidwa mu carbon ndikuyika pansi pa mphamvu ndi kutentha kwambiri kuti diamondi ikule.
Njira ina yotchuka yokulitsira diamnd yopanga ndi chemical vapor deposition (CVD).Kukula kumachitika pansi pa kupanikizika kochepa (pansi pa kupanikizika kwa mumlengalenga).Zimaphatikizapo kudyetsa mipweya yosakanikirana (yomwe nthawi zambiri imakhala 1 mpaka 99 methane kupita ku haidrojeni) mu chamver ndikuwagawa kukhala ma radicals omwe amagwira ntchito mu plasma yoyaka ndi ma microwave, filament yotentha, arcdischarge, torch kapena laser.Njirayi imagwiritsidwa ntchito kwambiri pakupaka, komanso imatha kupanga makhiristo amodzi mamilimita angapo kukula kwake.
