SI1-SI2 B Papa HPHT i hanaia e ke kanaka Daimana Pohaku No na Momi
- He aha ka Lab Grown Diamond
ʻO ka ʻokoʻa ma waena o kahi daimana kūlohelohe a me kahi lab i ulu ʻia mai ke ʻano i hana ʻia ai.Hana ʻia nā daimana i ulu ʻia e ke kanaka i loko o kahi lab a ʻo nā daimana kūlohelohe i hana ʻia ma ka honua.
Ua hana ʻia nā daimana synthetic mua loa ma ka hoʻohālike ʻana i ke ʻano me ka High Pressure/High Temperature (HPHT).ʻEkolu kaʻina hana maʻamau i hoʻohana ʻia no ka hana ʻana i nā daimana HPHT: ka paʻi kāʻei, ka paʻi cubic, a me ka paʻi split-sphere (BARS).ʻO ka pahuhopu o kēlā me kēia kaʻina hana ʻo ia ka hana ʻana i kahi kaiapuni o ke kaomi kiʻekiʻe loa a me ka mahana kahi e ulu ai ke daimana.Hoʻomaka kēlā me kēia kaʻina hana me kahi hua daimana liʻiliʻi i hoʻokomo ʻia i loko o ke kalapona a waiho ʻia ma lalo o ke kaomi kiʻekiʻe a me ka mahana e ulu ai ke daimana.
ʻO kekahi ala kaulana o ka ulu ʻana i ka diamnd synthetic he chemical vapor deposition (CVD).Aia ka ulu ma lalo o ke kaomi haʻahaʻa (ma lalo o ke kaomi lewa).Hoʻopili ia i ka hānai ʻana i ka hui ʻana o nā kinoea (maʻamau 1 a 99 methane i hydrogen) i loko o kahi chamver a hoʻokaʻawale iā lākou i nā radical hoʻoikaika kemika i loko o ka plasma i hoʻā ʻia e nā microwaves, filament wela, arcdischarge, welding torch a laser paha.Hoʻohana nui ʻia kēia ʻano no ka uhi ʻana, akā hiki ke hana i nā kristal hoʻokahi mau millimeters ka nui.
