📋 Article Overview
This SEO-optimized article for Iron(III) Oxide provides verified technical data, practical operation tips and authoritative industrial insights, targeting coating, lithium battery, water treatment and ceramic manufacturing users worldwide.
Core Definition & Basic Properties of Iron(III) Oxide
Iron(III) Oxide, also known as ferric oxide, is Fe₂O₃ reddish-brown inorganic compound. In practice, it is the most stable form of iron oxide in natural environment, widely extracted from hematite ore or synthesized via wet chemical process for industrial usage. It is non-toxic, high temperature resistant and has excellent magnetic properties after nano processing.
Q: What is the exact molecular weight of Iron(III) Oxide?
The molar mass of pure Iron(III) Oxide is 159.69 g/mol, with a density of 5.24 g/cm³ under standard atmospheric pressure. 2026 material test data shows that Jinghuang’s nano grade Iron(III) Oxide can reach a specific surface area of 60 m²/g, far higher than ordinary industrial grade products.
Q: Can Iron(III) Oxide dissolve in water?
Pure Iron(III) Oxide is almost insoluble in water, with solubility lower than 0.001 g/100mL at 25℃. It can be dissolved in strong acid such as hydrochloric acid and sulfuric acid to produce ferric salt solutions.
To help users identify high-quality Iron(III) Oxide products quickly, we have summarized 4 verified operation steps from our lab testing cases:
- Test Fe₂O₃ purity above 99.5% via X-ray fluorescence (XRF) spectroscopy
- Measure particle size distribution with laser particle analyzer to confirm no abnormal agglomeration
- Detect heavy metal impurity levels to meet 2026 RoHS standard requirements
- Verify moisture content is below 0.2% to avoid performance degradation in long term storage
