Synthetic Alexandrite - Yakatambanudzwa - Czochralski - Crystal Rise - Vhidhiyo
Zviri Mukati:
Alexandrite ndeimwe yematombo anoshamisa.
Tenga matombo echisikigo muchitoro chedu chematombo
synthetic alexandrite
Musiyano mukuru pakati pealexandrite nemamwe matombo ematombo ndiko kugona kwayo kwakasiyana kwekuchinja ruvara zvichienderana nemwenje weambient. Alexandrite yakasvibira yakasvibira kana uswa hwakasvibirira kana mwenje chena wekugadzira fluorescent uchishandiswa, asi inoshanduka yepepuru kana ruby muchiedza chezuva kana kenduru.
Ichi chiitiko chinonzi alexandrite effect uye chinowanzoshandiswa nemamwe maminerari anogona kuchinja ruvara. Semuenzaniso, magarnet anogona kuchinja ruvara anonziwo alexandrite garnets.
Alexandrite yakasiyana-siyana yemaminerari chrysoberyl. Iyo isina kujairika shanduko yemuvara inokonzerwa nekuvapo kwechromium ions mukristaro lattice. Parizvino, alexandrite yechisikigo inoonekwa seimwe yeakanakisa uye isingawanzo matombo ematombo.
Zvechokwadi, izvi zvakakonzera kuti fakes ionekwe pamusika iyo inongofanana zvishoma nedombo rekutanga, sezvo isingaratidzi maitiro akanaka ekuchinja kwemavara uye kutamba kwechiedza mukati mezvisikwa alexandrite. Corundum fakes yakajairika.
Czochralski process (yakabudiswa kunze)
Maitiro eCzochralski inzira yekukura kwekristaro inoshandiswa kugadzira makristasi ega ega semiconductors (eg silicon, germanium uye gallium arsenide), simbi (semuenzaniso palladium, platinamu, sirivheri, goridhe), munyu uye matombo anokosha ekugadzira. Maitiro aya anotumidzwa zita remusayendisiti wekuPoland Jan Czochralski, uyo akagadzira nzira iyi muna 1915 achidzidza chiyero chekristalllization yesimbi.
Akawana izvi netsaona, achiongorora mwero wecrystallization yesimbi, apo panzvimbo pokunyika peni muinki, akazviita mugaba rakanyungudutswa ndokuronda shinda yerata, iyo gare gare yakazova kristaro imwe.
Iyo inonyanya kukosha application inogona kunge iri kukura kwehombe cylindrical ingots kana spheres yeimwe crystal silicon inoshandiswa muindasitiri yemagetsi kugadzira semiconductor zvishandiso seyakasanganiswa maseketi.
Mamwe semiconductors akadai segallium arsenide anogonawo kukura neiyi nzira, kunyangwe yakaderera density mune iyi kesi inogona kuwanikwa uchishandisa akasiyana eiyo Bridgman-Stockbarger nzira.
