Iridium CAS: 7439-88-5

Iridium muaj ntau yam kev siv thoob plaws ntau yam lag luam, vim nws cov khoom siv lub cev thiab tshuaj lom neeg zoo heev. Ib qho ntawm nws cov kev siv tseem ceeb yog nyob rau hauv kev tsim cov khoom siv hluav taws xob ua tau zoo thiab cov hluav taws xob vim nws tiv taus kev hnav thiab xeb, ua rau nws tsis muaj txiaj ntsig zoo hauv kev siv tsheb thiab aerospace. Tsis tas li ntawd, iridium lub melting point siab thiab durability ua rau nws yog ib qho tseem ceeb hauv kev tsim cov crucibles thiab lwm yam khoom siv rau qhov kub thiab txias heev, xws li hauv cov ntaub ntawv ua thiab cov chaw soj nstuam tshawb fawb. Tsis tas li ntawd, iridium ua lub luag haujlwm tseem ceeb hauv kev ua catalysis, tshwj xeeb tshaj yog hauv kev tsim cov nitric acid thiab qee cov organic compounds. Nws muaj nyob rau hauv catalysts pab txhawb cov tshuaj tiv thaiv tseem ceeb, pab txhawb rau kev tsim cov tshuaj lom neeg tseem ceeb thiab cov tshuaj intermediates. Tsis tas li ntawd, iridium-based catalysts siv rau hauv kev lag luam tshuaj lom neeg thiab petrochemical rau cov txheej txheem xws li hydrogenation thiab oxidation, ua rau muaj kev tsim khoom zoo ntawm ntau yam tshuaj. Hauv cov khoom siv hluav taws xob thiab kev sib txuas lus, iridium yog siv rau hauv kev tsim cov khoom siv kub siab, cov khoom siv hluav taws xob, thiab ua cov khoom siv txheej rau cov khoom uas raug rau cov xwm txheej ua haujlwm hnyav. Nws qhov kev ntseeg siab nyob rau hauv qhov kub thiab txias heev thiab nws lub peev xwm los tiv thaiv oxidation thiab hnav ua rau nws yog ib qho khoom siv tseem ceeb rau kev ua kom lub neej ntev thiab kev ua tau zoo ntawm cov khoom siv hluav taws xob thiab cov kab ke sib txuas lus. Ntxiv mus, iridium pom cov ntawv thov hauv kev kho mob, qhov twg nws cov biocompatibility thiab kev tiv thaiv corrosion ua rau nws haum rau qee cov biomedical implants thiab cov khoom siv. Tsis tas li ntawd, iridium yog siv rau hauv kev kho mob hluav taws xob ua ib qho radioisotope rau kev kho mob qog noj ntshav, qhia txog nws lub luag haujlwm tseem ceeb hauv kev kho mob thiab kev txuag txoj sia. Zuag qhia tag nrho, iridium cov khoom zoo kawg nkaus tau ua rau nws siv dav hauv ntau yam lag luam, suav nrog tsheb, aerospace, electronics, kev kho mob, thiab ntau ntxiv. Nws cov kev koom tes rau cov khoom siv ruaj khov, cov txheej txheem tshuaj lom neeg, thiab kev nce qib hauv kev siv tshuab qhia txog nws qhov tseem ceeb hauv kev tsav tsheb tshiab thiab kev nce qib thoob plaws ntau yam kev lag luam, ua rau nws yog ib qho tseem ceeb hauv kev siv niaj hnub no thiab kev tshawb fawb.
