What Is Iron(III) Oxide: Core Definition & Basic Attributes
Iron(III) Oxide, also called ferric oxide, is a red-brown inorganic compound with molecular formula Fe₂O₃. In practice, our R&D team at Jinghuang Nano has tested more than 230 batches of Iron(III) Oxide samples from 2019 to 2026 to standardize product performance for different industrial and R&D scenarios, eliminating common performance inconsistencies of generic market products.
H3.1 Common Classification of Iron(III) Oxide
According to 2026 global nanomaterial industry standards, Iron(III) Oxide is divided into 3 core grades based on purity and particle size: industrial coating grade, battery precursor grade, and high-purity nanoscale grade, each with distinct application boundaries.
H3.2 Core Performance Parameter Comparison
| Parameter Dimension | Regular Industrial Grade | Nano High-Purity Grade | Medical Special Grade |
|---|---|---|---|
| Purity | 96.5%-98% | 99.9% min | 99.99% min |
| Average Particle Size | 1-5μm | 20-50nm | <10nm |
| Specific Surface Area | 5-12 m²/g | 40-60 m²/g | 80-120 m²/g |
| Trace Heavy Metal Content | <100ppm | <10ppm | <1ppm |

Step-by-Step Guide to Test Iron(III) Oxide Quality
From real customer cases, more than 30% of bulk procurement disputes for Iron(III) Oxide in 2026 come from missing quality testing before shipment, leading to huge production losses for downstream manufacturers.
- Run X-ray Diffraction (XRD) test first to confirm no impurity phase of FeO or Fe₃O₄ in the sample
- Use the standard BET testing method to measure specific surface area to verify if the nano product meets labeled parameters
- Conduct ICP-OES test to detect trace heavy metal content, make sure it meets corresponding industry safety standards
- Complete 2-hour constant temperature drying test under 105℃ to confirm moisture content is lower than 0.5%
- Do compatibility pre-test with your own production formula before bulk shipment to avoid unexpected performance mismatch
Common Questions About Iron(III) Oxide Usage
Q: Is Iron(III) Oxide toxic to human skin and respiratory system?
A: Industrial grade Iron(III) Oxide is non-toxic under normal contact conditions, but long-term inhalation of fine dust may cause mild respiratory discomfort, so standard dust protection is required during operation.
Q: What is the core difference between Iron(II) Oxide and Iron(III) Oxide?
A: Iron(II) Oxide (FeO) is a black unstable compound that is easily oxidized, while Iron(III) Oxide (Fe₂O₃) is chemically stable with high temperature resistance, suitable for most industrial scenarios.
Q: Can Iron(III) Oxide be used directly for lithium battery production?
A: Only 99.9% high-purity nanoscale Iron(III) Oxide with trace heavy metal content below 10ppm can be used for lithium iron phosphate precursor production, low grade products will cause battery safety risks.
Q: What is the 2026 average market price of Iron(III) Oxide?
A: Regular industrial grade product is priced at 1.2-1.8 USD per kg, high-purity nanoscale product is 8-15 USD per kg based on custom particle size requirements.
