Kuchera nzira dzescandium
Kwenguva yakati wandei mushure mekuwanikwa kwayo, kushandiswa kwe scandium hakuna kuratidzwa nekuda kwekuoma kwayo mukugadzira. Nekuwedzera kwekuvandudzwa kwezvisingawanzo kupatsanurwa kwepasi chinhu nzira, ikozvino kune yakakura nzira yekuyerera yekuchenesa scandium makomisheni. Nekuti scandium ine alkalinity isina kusimba kana ichienzaniswa neyttrium uye lanthanide zvinhu, hydroxides ine isingawanzo pasi chinhu chakasanganiswa zvicherwa zvine scandium. Mushure mekurapwa, scandium hydroxide inotanga kudonha kana yaendeswa kune mhinduro uye inorapwa neammonia. Naizvozvo, kushandiswa kwegiredhi nzira yekunaya kwemvura kunogona kuiparadzanisa zviri nyore kubva kune zvisingawanzo zvinhu zvepasi. Imwe nzira ndeye kushandisa hierarchical decomposition ye nitrate yekuparadzanisa, sezvo nitric acid ndiyo iri nyore kuora uye inogona kuzadzisa chinangwa chekuparadzanisa scandium. Uye zvakare, kudzoreredza kwakazara kwekuperekedza scandium muuranium, tungsten, tini uye mamwe mamineral deposits zvakare yakakosha sosi ye scandium.
Mushure mekuwana yakachena scandium komboni, inoshandurwa kuita ScCl3 uye yakanyungudutswa neKCI neLiCI. Zinc yakanyungudutswa inoshandiswa secathode ye electrolysis, zvichiita kuti scandium inaye pazinc electrode. Zvadaro, zinc inoputika kuti iwane metallic scandium. Iyi isimbi chena yesirivha yakareruka, uye maitiro ayo emakemikari anoshandawo zvakanyanya. Inogona kuita nemvura inopisa kugadzira hydrogen.
Scandiumine zvimiro zveyakaderera hama density (inoda kuenzana nealuminium) uye yakakwirira kunyungudika. Nitriding (SCN) ine nzvimbo yekunyungudika ye2900 ℃ uye yakakwirira conductivity, zvichiita kuti ishandiswe zvakanyanya mumaindasitiri emagetsi neredhiyo. Scandium ndechimwe chezvinhu zve thermonuclear reactors. Scandium inogona kumutsa phosphorescence ye ethane uye kuwedzera mwenje webhuruu we magnesium oxide. Kuenzaniswa nemarambi e-high-pressure mercury, marambi anopinza esodium ane zvakanakira senge mwenje wepamusoro uye neruvara rwakanaka rwechiedza, zvichiita kuti dzive dzakakodzera kudhiza mafirimu uye mwenje weplaza.
Scandium inogona kushandiswa sechinhu chinowedzera nickel chromium alloys muindasitiri yemetallurgical kugadzira alloys anodzivirira kupisa kwakanyanya. Scandium chinhu chakakosha mbishi mahwendefa ekuona pasi pegungwa. Kupisa kwekupisa kwe scandium kunosvika 5000 ℃, iyo inogona kushandiswa muhunyanzvi hwemuchadenga. Sc inogona kushandiswa kuronda radioactive kune zvakasiyana siyana. Scandium dzimwe nguva inoshandiswa mukurapa.
