Kev Siv Indium Hlau Hauv Cov Ntawv Siv Hluav Taws Xob thiab Optical
Indium yog ib hom hlau uas mos mos, yooj ywm, xim nyiaj-grey uas muaj qhov kub qis (kwv yees li 156,6 ° C). Txawm hais tias tsis paub zoo li tooj liab lossis txhuas, indium ua lub luag haujlwm tseem ceeb hauv kev siv tshuab niaj hnub no - tshwj xeeb tshaj yog hauv cov khoom siv hluav taws xob thiab optics. Indium tus nqi tseem ceeb yog los ntawm nws cov khoom sib xyaw ua ke: kev ua hluav taws xob zoo, lub peev xwm los tsim cov yeeb yaj kiab nyias ruaj khov, kev nplaum siab rau iav thiab qee yam khoom siv, thiab kev coj cwj pwm tshwj xeeb thaum ua ke nrog lwm cov ntsiab lus. Ua tsaug rau cov khoom no, indium siv dav hauv cov touchscreens, cov vaj huam sib luag hnub ci, cov khoom siv semiconductor, thiab cov khoom siv txheej optical.
1. Indium ua cov khoom siv tseem ceeb rau cov ntxaij vab tshaus niaj hnub: Indium Tin Oxide (ITO)
Kev siv indium zoo tshaj plaws hauv cov khoom siv hluav taws xob thiab optics yog ua lub ntsiab tivthaiv ntawm Indium Tin Oxide (ITO), ib qho sib xyaw ntawm indium oxide (In₂O₃) thiab tin oxide (SnO₂). ITO yog qhov tseem ceeb heev vim nws muaj ob yam khoom uas tsis tshua pom muaj nyob rau hauv cov ntaub ntawv tib lub sijhawm: nws yog hluav taws xob conductive tab sis pob tshab rau lub teeb pom kev zoo.
Nws yog qhov "pob tshab conductor" khoom uas ua rau ITO yog cov khoom siv txheem rau:
- Cov ntxaij vab tshaus kov tau ntawm cov xov tooj ntse thiab cov ntsiav tshuaj, qhov twg txheej ITO ua haujlwm ua lub electrode pob tshab los ntes kev kov.
