Liab Lead Oxide (Lead Tetroxide)
Liab Lead Oxide, tshuaj hu uaLead Tetroxide (Pb₃O₄), yog ib qho inorganic txhuas compound nrog cov khoom sib txawv thiab kev siv. Hauv qab no yog nws cov lus piav qhia ntxaws:
1. Cov ntaub ntawv yooj yim
Tshuaj Formula: Pb₃O₄
Molecular Luj: Kwv yees li 685.6 g / mol
CAS Nr: 1314-41-6
Cov Npe: Liab lead, minium, lossis liab lead oxide. Nws zoo nkaus li txiv kab ntxwv ci - liab lossis txiv kab ntxwv hnyav hmoov.
2. Lub cev thiab tshuaj muaj zog
Qhov ntomQhov hnyav: 9.1 g / cm³
Melting Point: Nyob ib ncig ntawm 500 degree
SolubilityInsoluble hauv dej thiab ethanol; Soluble nyob rau hauv kub alkaline daws, dilute nitric acid, acetic acid, thiab hydrochloric acid.
Lwm yam zoo: Nws muaj oxidizing zog. Thaum raug huab cua noo thiab tshav ntuj, nws maj mam tig grey. Nws decomposes rau hauv lead monoxide (PbO) thiab oxygen (O₂) thaum tshav kub tshaj 500 degree.
3. Txoj Kev Npaj
Nws yog tsim los ntawm cua sov lead monoxide (PbO) hauv huab cua ntawm 470-480℃rau ob peb teev. Cov tshuaj chemical yog raws li nram no:6Pb + O₂ → 2Pb₃O₄
4. Cov ntawv thov tseem ceeb
Ua haujlwm tseem ceeb los tiv thaiv - xeb xim hauv cov txheej txheem.
Siv rau hauv kev tsim cov roj teeb cia, iav, ceramics, thiab enamel.
Kev ua haujlwm ua tus neeg sawv cev oxidizing hauv dyes thiab cov txheej txheem organic synthesis.
Ua raws li cov xim liab inorganic los muab qhov ci, ntev - xim liab ntev rau ntau yam khoom.
5. Kev Nyab Xeeb Kev Nyab Xeeb
Lead thiab nws cov tebchaw yog tshuaj lom, ua rau cov hematopoietic, paj hlwb, digestive, thiab raum.
Classified ua aPawg 2A carcinogenlos ntawm IARC (International Agency for Research on Cancer).
Cov cuab yeej tiv thaiv kom zoo (xws li, lub qhov ncauj qhov ntswg, hnab looj tes) yuav tsum hnav thaum tuav kom tsis txhob nqus cov plua plav lossis kev sib cuag ntawm daim tawv nqaij.
Cim npe nrov: liab lead oxide rau antirust xim, iav, electron raj thiab ceramic thiab lwm yam, Tuam Tshoj, manufacturers, lwm tus neeg, Hoobkas, pheej yig, luv nqi, hais, luv nqi, dawb qauv
