1. A ferric oxide synthesis method, comprising:
heating a composition comprising a ferric halide and an alkali metal salt of a carboxylic acid in hexane at a temperature of 150-300° C. in a sealed container to form ferric oxide microparticles, wherein the ferric halide is selected from the group consisting of ferric chloride and ferric bromide; and
contacting an ammonium salt with the ferric oxide microparticles,
wherein the ferric oxide microparticles have an octahedron morphology and a particle diameter of about 4.3 μm,
wherein on the contacting the ammonium salt is decomposed, and
wherein the ammonium salt has a final decomposition temperature of 420° C.
