I-Scandium Metal Sc Metal
Ulwazi olufushane
Igama lomkhiqizo: I-Scandium metal
Ifomula: Sc
Inombolo ye-CAS: 7440-20-2
Isisindo se-molecule: 44.96
Ukuminyana: 2.99 g/cm3
Indawo yokuncibilika: 1540 °C
Indawo yokubilisa:2831℃
Ukubukeka: Ingot yensimbi empunga esiliva, isiponji, umumo wenaliti, i-silvery white metallic luster, Ingasikwa ngokwezidingo zekhasimende
Izimpawu Zomzimba: Umkhiqizo umhlophe wesiliva, ngokuvamile usesimweni samabhulokhi acwebezelayo acwebile (njengenyama) ensimbi.Ukusakaza, amabhlokhi isipontshi, noma amalensi nakho kungaba ngendlela yokulingisa okumise okwenkinobho, kube nendawo ehlanzekile.Kulula ukuncibilika emanzini, kungasabela ngamanzi ashisayo, futhi kube mnyama kalula emoyeni.
Isicelo:
I-Scandium Metalisetshenziswa embonini ye-optical coating, catalyst, electronic ceramics kanye ne-laser.Ukusetshenziswa okuyinhloko kweScandium ngesisindo kuku-Aluminium-Scandium alloys yezingxenye ezincane zemboni ye-aerospace.Ezinye izinto zemishini yezemidlalo, ethembele ezintweni zokusebenza eziphezulu, zenziwe nge-Scandium-Aluminium alloys.Kuqashwe esimweni esiqinile sokuhlanganiswa kwamaqoqo angajwayelekile, i-Sc19Br28Z4, (Z=Mn, Fe, Ru noma Os).Lawa maqoqo anentshisekelo ngesakhiwo sawo kanye nezakhiwo kazibuthe.Iphinde isetshenziswe ekwenzeni i-super alloy.Scandium metal isetshenziswa ku-high-tech alloy materials, imithombo yokukhanya kagesi, izimboni zamaseli kaphethiloli, izimboni zamandla enuzi, nezimboni zempi ubuchwepheshe, ubuchwepheshe be-superconducting, neminye imikhakha.
