Formation
Iron(II) molybdate is created by the reaction of iron(II) chloride or iron(II) sulfate[2] and sodium molybdate.
Applications
FeMoO4 has been used as relatively stable active material for anodes in Li-ion batteries for conversion reaction,[3] as anode material in aqueous supercapacitors due to fast redox reactions[2] and as catalyst for oxygen evolution in alkaline solutions.[4]
Safety
Iron(II) molybdate is toxic and may cause irritation. It should not be released into the environment. Inhalation of dusts should be avoided.
gollark: A lot of the time it's just because it's not "natural" or something, which seems stupid and meaningless.
gollark: > >not buying a box of 10,000 BIC blue pens10000, you say? Where can I buy such quantities?
gollark: I bought a box of 100 on Amazon some years back, very helpful.
gollark: I haven't received any information on how they plan to mitigate coronavirus risk.
gollark: Mine restarts in twoish weeks.
