Ntchito zazikulu za scandium

Ntchito zazikulu za scandium

Kugwiritsa ntchitoscandium(monga chinthu chachikulu chogwirira ntchito, osati cha doping) chimakhazikika munjira yowala kwambiri, ndipo sikukokomeza kuyitcha kuti Mwana wa Kuwala.

1. Nyali ya sodium ya Scandium

Chida choyamba chamatsenga cha scandium chimatchedwa scandium sodium nyale, yomwe ingagwiritsidwe ntchito kubweretsa kuwala kwa zikwi za mabanja. Ichi ndi gwero lamagetsi lamagetsi la halide: sodium iodide ndi scandium iodide zimayikidwa mu babu, ndipo scandium ndi zojambulazo zimawonjezeredwa. Pakutuluka kwamphamvu kwambiri, ma scandium ma ion ndi ayoni a sodium amatulutsa mawonekedwe awo otulutsa kuwala, motsatana. Mizere yowoneka bwino ya sodium ndi mizere iwiri yachikasu yodziwika bwino, 589.0nm ndi 589.6nm, pomwe mizere yowoneka bwino ndi mndandanda wamtundu wapafupi ndi ultraviolet ndi buluu wotuluka kuchokera ku 361.3-424.7nm. Pamene akuthandizana, mtundu wonse wopangidwa ndi kuwala koyera. Ndi chifukwa chakuti nyali za sodium za scandium zimakhala ndi mphamvu zowala kwambiri, kuwala kwabwino, kupulumutsa mphamvu, moyo wautali wautumiki, ndi mphamvu yowononga chifunga yomwe imatha kugwiritsidwa ntchito kwambiri pamakamera a kanema wawayilesi, mabwalo, malo ochitira masewera, ndi kuyatsa misewu, ndipo amadziwika ngati magwero a kuwala kwa m'badwo wachitatu. Ku China, nyali yamtunduwu imalimbikitsidwa pang'onopang'ono ngati teknoloji yatsopano, pamene m'mayiko ena otukuka, nyali yamtunduwu idagwiritsidwa ntchito kwambiri kumayambiriro kwa zaka za m'ma 1980.

2. Maselo a dzuwa a photovoltaic

Chida chachiwiri chamatsenga cha scandium ndi maselo a dzuwa a photovoltaic, omwe amatha kusonkhanitsa kuwala komwe kunabalalika pansi ndikusandutsa magetsi kuti ayendetse anthu. Muzitsulo zotchingira semiconductor silicon solar cell ndi ma cell a solar, ndiye chitsulo chotchinga bwino kwambiri.

3. γ Gwero la radiation

Chida chachitatu chamatsenga cha scandium chimatchedwa γ Gwero la ray, chida chamatsenga ichi chikhoza kuwala pachokha, koma kuwala kotereku sikungathe kulandiridwa ndi maso, ndi mphamvu ya photon yothamanga kwambiri. Nthawi zambiri timachotsa 45 Sc kuchokera ku mchere, yomwe ndi isotope yokha yachilengedwe ya scandium. Khungu lililonse la 45 Sc lili ndi ma protoni 21 ndi ma neutroni 24. 46Sc, isotopu yopangira ma radioactive, ingagwiritsidwe ntchito ngati γ magwero a radiation kapena ma atomu ofufuza angagwiritsidwenso ntchito pochiritsa zotupa zoyipa. Palinso ntchito monga scandium garnet lasers, fluorinated glass infrared optical fiber, ndi cathode ray chubu yokutidwa ndi scandium pa TV. Zikuwoneka kuti scandium idabadwa ndi kuwala.

4. Zokometsera zamatsenga

Zomwe tatchulazi zinagwiritsidwa ntchito pa scandium, koma chifukwa cha mtengo wake wokwera komanso mtengo wake, mankhwala ambiri a scandium ndi scandium sagwiritsidwa ntchito kawirikawiri m'mafakitale, pogwiritsa ntchito zojambulazo zopyapyala ngati mu babu. M'madera ambiri, mankhwala a Hetong amagwiritsidwa ntchito ngati zokometsera zamatsenga, monga mchere, shuga, kapena monosodium glutamate m'manja mwa ophika. Ndi pang'ono chabe, amatha kumaliza.

5. Zokhudza anthu

Sizikudziwika ngati scandium ndi chinthu chofunikira kwa anthu. Scandium imapezeka m'thupi la munthu. Amaganiziridwa kuti ali ndi carcinogenicity. Scandium imakonda kupanga maofesi okhala ndi magulu a 8-light, omwe angagwiritsidwe ntchito pofufuza scandium. Neutron radiometric kusanthula angagwiritsidwe ntchito kudziwa quantification pansipa ng/g.
