📋 Article Overview
This E-E-A-T compliant resource breaks down all key details of Iron(III) Oxide for industrial buyers, R&D teams and coating producers, integrating real production data from Jinghuang Nanomaterials 2026 inventory.
What Is Iron(III) Oxide: Core Definition
Iron(III) Oxide is a red-brown inorganic compound with formula Fe₂O₃, the most stable oxide of iron. As the main component of rust and iron ore hematite, it is one of the most widely used low-cost functional inorganic materials in modern industries. In our 12 years of production practice at Jinghuang Nanomaterials, we have delivered over 2300 tons of qualified Iron(III) Oxide products to 130+ countries globally up to 2026.
Q: Is Iron(III) Oxide the same as common rust?
A: No. Natural rust contains impurities like hydrated iron oxides and heavy metal residues, while industrial grade Iron(III) Oxide is refined to reach 98%+ purity for targeted industrial usage.
Q: What is the standard molar mass of Iron(III) Oxide?
A: The molar mass of pure Iron(III) Oxide is 159.69 g/mol, with a melting point of 1565℃ under standard atmospheric pressure.
Key Physical & Chemical Properties of 2026 Commercial Iron(III) Oxide
Actual lab tests from Jinghuang R&D center show that high-purity nano Iron(III) Oxide has far better performance than traditional micron grade products in catalysis, magnetism and tinting strength. The table below lists 2026 mainstream commercial product parameters:
| Parameter | 98% Industrial Grade | 99.5% Coating Grade | 99.9% Nano Grade |
|---|---|---|---|
| Average Particle Size | 1-5 μm | 0.5-1 μm | 20-50 nm |
| Tinting Strength | 92% | 100% | 128% |
| Heavy Metal Content | ≤ 1000 ppm | ≤ 100 ppm | ≤ 10 ppm |
| Jinghuang Supply Lead Time | 3-7 working days | 5-10 working days | 7-15 working days |
Recent 2026 research from the American Ceramic Society confirms that nano Iron(III) Oxide as a dopant for lithium battery anode materials can boost the full charge cycle life by 27% compared with traditional additive formulas.

Main Industrial Application Scenarios of Iron(III) Oxide
From 2000+ global client cases we handled in 2025-2026, Iron(III) Oxide covers more than 12 major industrial sectors, with 72% of total global output used in coating, construction and new energy sectors.
Coating & Construction Field
Iron(III) Oxide red pigment has excellent weather resistance, UV blocking performance and alkali resistance, it is the most widely used colorant for exterior wall paint, concrete pavement and ceramic tiles, with service life over 20 years without obvious color fading.
New Energy & Catalysis Field
Nano Iron(III) Oxide is widely used as a precursor for lithium iron phosphate production, as well as a Fenton catalyst for industrial wastewater treatment, with 3 times higher catalytic efficiency than traditional micron grade products.
5-Step Quality Inspection Protocol for Iron(III) Oxide Bulk Procurement
To avoid unqualified products that fail your production line, we recommend all industrial buyers follow this strict inspection flow before confirming large order shipments:
- Verify third-party XRF purity test report provided by the supplier to confirm no excess heavy metal impurities
- Test particle size distribution via laser granulometer to match your production formula requirements
- Run tinting strength test with your existing raw materials to make sure color difference is below ΔE=1
- Confirm moisture content is lower than 0.5% to avoid caking during long-term storage
- Check packaging integrity with waterproof inner bag and ton bag to avoid leakage in cross-border transportation
Industry consensus is that suppliers who can provide full batch test reports before shipment have 98% lower after-sales defect rate than those who can only provide post-shipment reports.
2026 Market Trend of Iron(III) Oxide Supply Chain
Affected by global new energy industry expansion, the global demand for high-purity nano Iron(III) Oxide in 2026 increases by 19% year on year, while traditional low-grade industrial grade product supply remains stable with price fluctuation lower than 5%.
Q: Can Iron(III) Oxide be used for food contact packaging products?
A: Only 99.9% food grade Iron(III) Oxide that meets EU 10/2011 regulation can be used for food contact materials, ordinary industrial grade products are forbidden for such usage.
Q: Is Iron(III) Oxide soluble in water?
A: Pure Iron(III) Oxide is insoluble in water, ethanol and weak acid, it can only be dissolved in concentrated strong acid like hydrochloric acid and sulfuric acid.
Frequently Asked Questions
Q: What is the shelf life of properly stored Iron(III) Oxide powder?
A: Under dry and sealed storage condition, qualified Iron(III) Oxide can keep stable for 3 years without obvious performance degradation or quality change.
Q: Does Jinghuang provide custom sized Iron(III) Oxide products for R&D use?
A: Yes, Jinghuang provides 20nm to 10μm custom particle size Iron(III) Oxide products, as well as 50g small lab sample packages for R&D teams.
Q: Is Iron(III) Oxide toxic for normal industrial operation?
A: Iron(III) Oxide is low-toxic common inorganic material, long-term inhalation of fine dust may cause minor respiratory irritation, so normal dust protection is required during operation.
Q: What is the 2026 average bulk price of industrial grade Iron(III) Oxide?
A: 2026 global average bulk price of 98% industrial grade Iron(III) Oxide ranges from $1.2 to $1.8 per kg, nano grade products are priced at $15 to $45 per kg based on different specs.
