Hi, I've been asked to heat a sample that contains Fe2O3, amongst some other things, to a temperature where Fe2O3 will decompose. I am unable to find the temperature at which I would need to heat the sample and I'm not entirely convinced this is actually possible with the equipment I have available. However, it would be greatly appreciated if anyone could provide me with this temperature and if possible a reference to go with it.
Thanks :)

The Ellingham diagrams in the above link suggest that $Fe_2O_3$ decomposes into $Fe_3O_4$ and $O_2$ at around 1500°C. Further decomposition to iron metal probably requires several thousand degrees. If "some other things" include, e.g., carbon or another reducing agent, then you can get a redox reaction to happen at a low(-ish, but still probably around 1000°C) temperature.
