This is the raw, uncalcined material. There are many hydrate forms and it this material is complex to research. This chemistry is from the data sheet of a commercial product used in ceramics.

Used by potters to develop iron red oxidation colors.

This material calcines at 140C (but this may be reversible as it cools).
At 500C it decomposes (into Fe2O3 and P2O5 vapor).
