- Waa maxay Dheeman Lab Grown
Farqiga u dhexeeya dheemanka dabiiciga ah iyo shaybaadhka koray ayaa ka yimid sida loo sameeyay.Dheemanka shaybaadhka lagu beeray waa nin-ku-sameeyay shaybaadhka halka dheemanka dabiiciga ah laga abuuray dhulka.
Dheemankii ugu horreeyay ee lagu guulaysto ayaa lagu sameeyay iyadoo lagu dayanayo dabeecadda soo saarista Cadaadis Sare/ Heer kulka Sare (HPHT).Waxaa jira saddex hab oo wax-soo-saar aasaasi ah oo loo isticmaalo samaynta dheeman HPHT: saxaafadda suunka, saxaafadda cubic, iyo saxaafadda kala qaybsan (BARS).Hadafka geeddi-socod kastaa waa in la abuuro jawi cadaadis aad u sarreeya iyo heerkul aad u sarreeya halkaas oo korriinka dheemanku ku dhici karo.Nidaam kastaa wuxuu ku bilaabmaa abuur yar oo dheeman ah kaas oo lagu dhejiyo kaarboon oo la geliyo cadaadis aad u sarreeya iyo heerkul si uu u koro dheemanka.
Habka kale ee caanka ah ee koraya diamnd synthetic waa kaydinta uumiga kiimikada (CVD).Koritaanku wuxuu ku dhacaa cadaadis hooseeya (ka hooseeya cadaadiska atmospheric).Waxay ku lug leedahay quudinta isku-darka gaas (sida caadiga ah 1 ilaa 99 methane ilaa hydrogen) oo la geliyo chamver oo loo kala qaybiyo xag-jiryo kiimikaad leh oo ku jira balaasma ay shido microwaves, fiilo kulul, qulqulo, shumaca alxanka ama leysarka.Habkan waxaa inta badan loo isticmaalaa daaha, laakiin sidoo kale soo saari kara crystals hal dhowr millimitir oo cabbirka.
