Hlau oxide pigment yog ib qho tseem ceeb heev inorganic xim xim nrog cov xim zoo nkauj thiab daim ntawv thov dav.
Cov txheej txheem ntawm kev tsim cov hlau oxide liab tau muab faib ua txoj kev qhuav thiab txoj kev ntub dej. Txoj kev qhuav mas suav nrog ntsuab vitriol (xws li ferrous sulfate heptahydrate) calcination txoj kev, hlau daj calcination txoj kev, hlau dub calcination txoj kev, ntxiv rau hematite calcination txoj kev. Ultrafine crushing txoj kev ntawm ntuj hlau oxide minerals siv ore li raw khoom, thiab lwm yam.
Cov txheej txheem ntub dej feem ntau suav nrog sulfate (xws li ferrous sulfate los yog cov tshuaj uas muaj ferrous sulfate), nitrate (xws li ferric nitrate, ferrous nitrate lossis cov tshuaj uas muaj ferric nitrate), txoj kev sib xyaw acid; Tus neeg sawv cev nruab nrab siv rau hauv cov txheej txheem oxidation yog txawv, thiab tuaj yeem muab faib ua cov ntawv hlau thiab txoj kev ammonia.
