alexandrite ea maiketsetso
Phapang e kholo lipakeng tsa alexandrite le mahakoe a mang ke bokhoni ba eona bo ikhethang ba ho fetola 'mala ho latela khanya e teng. Alexandrite e boputsoa bo botala kapa joang bo botala ha ho sebelisoa mabone a masoeu a maiketsetso a fluorescent, empa a fetoha pherese kapa a ruby red ka khanya ea letsatsi kapa kerese.
Ketsahalo ena e bitsoa phello ea alexandrite 'me e atisa ho sebelisoa le liminerale tse ling tse ka fetolang' mala. Ka mohlala, li-garnet tse ka fetolang 'mala li boetse li bitsoa alexandrite garnets.
Alexandrite ke mefuta e sa tšoaneng ea mineral chrysoberyl. Phello e sa tloaelehang ea phetoho ea 'mala e bakoa ke boteng ba li-ion tsa chromium ka lesela la kristale. Hona joale, alexandrite ea tlhaho e nkoa e le e 'ngoe ea mahakoe a matle ka ho fetisisa le a sa tloaelehang.
Ha e le hantle, sena se entse hore li-fake li hlahe 'marakeng tse tšoanang le lejoe la pele hanyenyane feela, kaha ha li bontše phello e ntle ea phetoho ea' mala le papali ea leseli ka hare ho alexandrite ea tlhaho. Li-fake tsa Corundum li atile haholo.
Ts'ebetso ea Czochralski (e ntšoa)
Ts'ebetso ea Czochralski ke mokhoa oa ho holisa kristale o sebelisoang ho hlahisa likristale tse le 'ngoe tsa li-semiconductors (mohlala, silicon, germanium le gallium arsenide), tšepe (mohlala, palladium, platinum, silevera, khauta), letsoai le majoe a maiketsetso. Ts'ebetso ena e rehiloe ka rasaense oa Lepolishe Jan Czochralski, ea qapileng mokhoa ona ka 1915 ha a ntse a ithuta sekhahla sa kristale ea tšepe.
O ile a sibolla sena ka tsietsi, ha a ntse a batlisisa lebelo la ho qhibiliha ha litšepe, ha ho e-na le ho qoelisa pene ka har’a enke, o ile a etsa joalo ka lesenke le qhibilihisitsoeng ’me a latella khoele ea thini, eo hamorao e ileng ea fetoha kristale e le ’ngoe.
Kopo ea bohlokoa ka ho fetisisa e ka 'na ea e-ba kholo ea li-ingots tse kholo tsa cylindrical kapa likaroloana tsa silicon e le' ngoe ea kristale e sebelisoang indastering ea elektronike ho hlahisa lisebelisoa tsa semiconductor tse kang lipotoloho tse kopantsoeng.
Li-semiconductors tse ling tse kang gallium arsenide le tsona li ka holisoa ka mokhoa ona, le hoja li-densities tse fokolang tabeng ena li ka fumanoa ho sebelisoa mefuta e sa tšoaneng ea mokhoa oa Bridgman-Stockbarger.
