Method of manufacturing aluminum-substituted hematite |
摘要 |
A method of manufacturing aluminum-substituted hematite represented by alpha-(Fe1-xAlx)2O3 where x=0.01 to 0.15, by mixing an iron compound and an aluminum compound such that an atomic ratio of Fe to Al falls within the range of 99:1 to 85:15, adding citric acid and ethylene glycol to the mixture of the iron compound and aluminum compound to produce a gel, and pyrolyzing the gel, followed by calcining the pyrolyzed product.
