I want to make Manganese Zinc Ferrite.
For that I took MnCl2.4H2O, ZnCl2, FeCl3.6H2O as precursor.
My final product should be Mn0.5Zn0.5Fe2O4
I assume the equation as
aMnCl2.4H2O + bZnCl2 + cFeCl3.6H2O + dO2 (oxygen from environment) ----> Mn0.5Zn0.5Fe2O4 + H2O + Cl2
Is my equation correct?
In the preparation route,
I first dissolve Iron chloride hexa hydrate in DI water and after that add the solution of remaining two salts.
Can anybody suggest me if I am right or wrong?
you have add a base like NaOH or KOH or ammonia etc then NaCl or KCl or other chloride salt, then only ferrite is oxidised by hydroxide and at particular temperature and pH one will get the required spinel phase.
chlorine gas will not go away from the mixture just like that.
You may simply take molar ratio of the metal chlorides for eg. 0.5M MnCl, 0.5M ZnCl and 1M FeCl for the mentioned composition.
You may go through following article.

I think Elangbam has given a precise method. Note that all the metallic elements are from the transition series and hence converting it to the oxide (from the hydroxide) is very essential. Secondly, you must maintain an acidic pH. Otherwise the hydroxide will be very complex (most of the time polynucleated) something like a jarosite and then you ill not get the desired porosity.
