CAS: 13446-49-6|Potassium Molybdate

Khoom Description

Potassium molybdate, tseem hu ua Dipotassium molybdate thiab Potassium molybdate (VI), muaj CAS No. ntawm 13446 - 49 - 6 thiab EINECS No. ntawm 236 - 599 - 2. Nws cov mis molecular yog K₂MoO₄, thiab qhov hnyav molecular yog 238.13.

Potassium molybdate yog cov hmoov dawb uas tsim los ntawm kev hloov pauv hlau molybdenum, alkali hlau potassium, thiab tsis yog - hlau oxygen cov ntsiab lus. Nws nthuav tawm raws li cov hmoov dawb dawb lossis tetragonal prism siv lead ua. Lub melting point yog kwv yees li 919 degree, lub boiling point yog nyob ib ncig ntawm 1400 degree, thiab tus txheeb ze ceev yog hais txog 2.91 g / cm³. Nws yog soluble hauv dej. Ntawm 20 degree, 100 g ntawm dej tuaj yeem yaj 160 g ntawm K₂MoO₄. Cov tshuaj aqueous yog alkaline thiab insoluble hauv ethanol. Nws ruaj khov ntawm chav tsev kub thiab siab, nthuav tawm cov khoom tsis zoo, tsis yog - tshuaj lom, tsis yog - corrosive, thiab muaj kev ua haujlwm zoo photocatalytic thiab electrochemical stability.

Siv

Kev siv: Potassium Molybdate feem ntau yog siv los ua catalyst thiab flotation tus neeg sawv cev rau hlau ore. Hauv kev ua cov roj av thiab tshuaj lom neeg, nws tuaj yeem siv rau oxidation cov tshuaj tiv thaiv thiab sulfidation cov tshuaj tiv thaiv xws li catalytic cracking thiab catalytic oxidation desulfurization, thiab tseem siv los rho molybdenum thiab tooj liab los ntawm cov hlau ore.
Kev siv ua liaj ua teb: Nws tuaj yeem siv los ua molybdenum thiab potassium qhov chaw rau cov nroj tsuag thiab av, txhawb cov nroj tsuag nitrogen metabolism thiab kev loj hlob thiab kev loj hlob, thiab muaj txiaj ntsig zoo rau kev loj hlob ntawm taum thiab cov qoob loo cruciferous. Nws tseem tuaj yeem txhim kho cov kab mob tiv thaiv kab mob thiab txhawb kev txhim kho txiv hmab txiv ntoo.
Kev siv tshuaj kho mob: Nws yog siv los npaj qee yam tshuaj raw cov ntaub ntawv, thiab tseem tuaj yeem siv los ua cov kab mob radioactive rau kev kuaj tshuaj nuclear thiab kev kuaj mob raum.
Lwm yam kev siv: Nws yog siv los npaj cov pigments thiab enamels, thiab tuaj yeem siv los ua cov xim rau iav thiab ceramics los muab cov khoom tshwj xeeb xim thiab cov khoom.
