He helena'ōmaʻomaʻo ka'ōmaʻomaʻo'ōmaʻomaʻo a Kelenato ma ka hoʻohanaʻiaʻana o nā kukui uila keʻokeʻo keʻokeʻo, akā i ka loleʻulaʻula a iʻole ka peni-ula i ka lā a me ke kukui. Kapaʻia kēiaʻano keʻano o ka hana alexandrite, a hoʻohanaʻia me nā meaʻokoʻa'ē aʻe e hiki ai ke hoʻololi i ka'ōuli.

ʻO Alexandrite heʻano nui o ka mineral chrysoberyl. ʻO ka hopena o ka hoʻololi keʻano'ēʻole no ka hikiʻana mai o nā kinona chromium i loko o ka'ōmole aniani. I kēia manawa,ʻikeʻia ke alexandrite maoliʻoiai kekahi o nā momona nani loa. ʻO keʻano,ʻo kēia ka hopena i kaʻikeʻana i nā mea kūʻai ma ka mākeke, kahi wale nō e like me ka pōhaku kumu keʻole lākou e noʻonoʻo i keʻano o ka loli nui a me ka māmā e hana ai i loko o ka alexandrite maoli.

Kuhi Czochralski (huki)

ʻO ka hana Czochralski heʻano o ka ulu ulu aniani i hoʻohanaʻia no ka loaʻaʻana o nā kinikaliki hoʻokahi o semiconductors (e like me ke'anouma, germanium a me ka gallium arsenide), nā metala (eg palladium, platinum, silver, gold), salts and synthetic gemstones. Ua kapaʻia ka papahana ma hope o ke kākā'ōlelo Polish Polish Jan Czochralski, nāna i hoʻololi i keʻano i ka 1915 i ka nānāʻana i nā kaʻina helu crystallization o nā metala. Uaʻikeʻo ia i kēiaʻike ma kahi pōpilikia,ʻoiaiʻo ia e aʻo ana i ka'ōwili o ka metals i ka manawa, ma kahi o ka peniʻana i kāna peni i ka'īnika, hanaʻo ia pēlā i loko o ke kōmole i hoʻoheheʻeʻia a huki i kahi ohe filament,

ʻO ka noi nui loa paha,ʻo ia ka uluʻana o ka'ōmole'ōmole nui, a me ka boule, o ke kinikuma kilokilo'eleka i hoʻohanaʻia ma kaʻoihana kelepona e hoʻohālikelike i nā polokalamu hoʻohālike me nā integrated integrated. Hiki ke hoʻonuiʻia kekahi mau semiconductors, e like me ke gallium arsenide, ma kēiaʻano, akā, hiki ke loaʻa i nāʻanoʻeleʻele hemahema ma kēia hihia ma o nāʻano likeʻole o keʻano Bridgman-Stockbarger.
