설명

일반 설명

Iron(II) sulfate heptahydrate is a heptahydrate of iron(II) sulfate. It undergoes thermal degradation to afford hydrosulfate and oxysulfate of iron(III). Isothermal and dynamic thermal analysis methods have been proposed to study its thermal decomposition in air.

애플리케이션

Iron(II) sulfate heptahydrate (FeSO₄.7H₂O) may be used in the synthesis of maghemite nanoparticles.

포장

bottled under inert gas

주의사항

tends to oxidation by air
