Manganese Tetraoxide (Mn3O4) muaj ntau qhov zoo, tsuas yog tshuaj rau hauv nws cov txheej txheem ntawm lub cev thiab tshuaj, kev thov hauv cov khoom tshiab manganese-raws li cov khoom siv electrode zoo.
Lub cev thiab tshuaj
Manganese Tetraoxide belongs rau chav kawm Spinel, uas muaj kev sib txawv thiab kev sib tw ions manganisis e muab faib ua ob txoj haujlwm sib txawv. Cov pa oxygen yog cov cub tawg kom nruj, muaj kev sib txawv manganese ions nyob rau hauv vetrans, thiab kev sib tw manganese ions odeahedral voids. Manganese Tetraoxide muaj deformed tetragonal spripors qauv thaum qhov kub nyob qis dua 1443k, thiab lub cubic spinel qauv saum 1443k. Manganese Tetraoxide yog insoluble hauv dej, tab sis soluble hauv concochloric acid thiab concentrated sulfuric acid.
Npaj txheej txheem
Muaj ob lub ntsiab kev npaj rau manganese tetraoxide: hlau manganese oxidation txoj kev thiab manganese sulfate oxidation txoj kev. Cov hlau manganese oxidation txoj kev tam sim no yog txoj kev txheej txheem tshaj lij. It uses electrolytic manganese as the raw material, grinds it into a manganese suspension, introduces air under specific temperature and catalyst conditions for oxidation, and finally obtains the manganese tetraoxide product through filtering, washing, drying and other processes. Cov manganese sulfate oxidation txoj kev yog npaj los ntawm ob-kauj ruam oxidation txoj kev. Ua ntej, sodium hydroxide tau ntxiv rau lub siab-huv mangorge sulfate daws kom nruab nrab nws thiab ua kom premas. Cov nag daus yog ntxuav ob peb zaug thiab tom qab ntawd oxygen tau qhia rau oxidation. Tom qab ntawd, ntxuav, lim, kev laus, slurry sib tov thiab ziab yog nqa tawm.
