Release time:
2026-06-09
This 2026-focused guide covers core properties, common industrial applications, quality testing standards and bulk procurement tips for Iron(III) Oxide, drawing on 12 years of nanomaterial manufacturing experience from Jinghuang Technology, helping global buyers select matching products, reduce procurement risks and lower overall material costs for downstream production.
📋 Guide Overview
This full reference is designed for industrial material purchasers, R&D researchers and production engineers who need accurate, up-to-date information on Iron(III) Oxide, with verified 2026 industry data and hands-on production experience shared directly by Jinghuang’s technical team.
What Exactly Is Iron(III) Oxide: Core Definition
Iron(III) Oxide is a inorganic iron oxide compound with chemical formula Fe₂O₃, also known as ferric oxide. It is one of the most stable oxidation states of iron, presenting as reddish-brown or dark red crystalline powder at normal temperature and pressure. In practice, Jinghuang’s technical team has confirmed that 92% of commercially supplied Iron(III) Oxide is produced via hydrothermal synthesis method to avoid heavy metal impurities.
Actual test表明，Iron(III) Oxide features excellent weather resistance, UV stability and inert chemical properties that make it suitable for long-term outdoor exposure scenarios. 2026 industry data shows that global annual demand for Iron(III) Oxide has exceeded 3.2 million tons, with 37% of demand coming from advanced manufacturing sectors such as lithium battery cathode materials and precision ceramics.
Key Physical and Chemical Properties of Iron(III) Oxide
Before selecting Iron(III) Oxide for specific production scenarios, users need to confirm core property parameters to avoid application mismatches that cause production losses.
Q: What is the melting point of high purity Iron(III) Oxide?
A: The standard melting point of pure Iron(III) Oxide is 1565°C, and it will decompose to ferrous ferric oxide and oxygen at temperatures higher than 1400°C under normal pressure.
Q: Is Iron(III) Oxide soluble in water?
A: Pure Iron(III) Oxide is completely insoluble in water, slightly soluble in strong acid, and fully soluble in concentrated hot hydrochloric acid and sulfuric acid solutions.
- Check the color consistency of the sample: high purity Iron(III) Oxide presents uniform reddish brown without variegated black or yellow particles
- Test the pH value of 10% water mixed slurry, qualified products show neutral pH between 6.5 to 8.0
- Conduct loss on drying test under 105°C for 2 hours, the moisture content should be lower than 0.5% for industrial grade products
- Send sample for XRD crystal phase detection to confirm no ferrous oxide impurity exists

| Purity Grade | Average Particle Size | Specific Surface Area | 2026 Unit Price (per kg) | Main Application |
|---|---|---|---|---|
| Industrial Grade 98.5% | 1-5μm | 5-15 m²/g | $1.2-$2.5 | Concrete pigment, coating additive |
| High Purity 99.9% | 50-200nm | 30-60 m²/g | $8-$18 | Lithium battery precursor, precision ceramic |
| Ultra High Purity 99.99% | 20-50nm | 60-120 m²/g | $45-$75 | Semiconductor polishing, catalyst carrier |
Industry consensus shows that nano-sized Iron(III) Oxide with particle size below 100nm has 3-5 times higher catalytic activity than micron grade products under the same reaction conditions.
Main Commercial Applications of Iron(III) Oxide 2026
Iron(III) Oxide is one of the most widely used inorganic functional materials across multiple industries, with new application scenarios expanded rapidly in recent years.
Q: Is Iron(III) Oxide the same as common rust?
A: The main component of rust is hydrous Iron(III) Oxide, but commercial purified Iron(III) Oxide removes moisture and other impurities to reach stable industrial grade quality for production use.
Q: Is Iron(III) Oxide toxic for daily use?
A: Food grade Iron(III) Oxide approved by FDA is non-toxic, widely used as food colorant, while industrial grade products may contain residual heavy metal impurities and cannot be used in food contact scenarios.
From past Jinghuang supply cases, 62% of our 2026 Iron(III) Oxide orders are for customers producing lithium iron phosphate cathode materials, where strict control of trace impurity content is the top priority to guarantee battery cycle life.
Bulk Procurement Tips for Iron(III) Oxide Buyers
To avoid quality discrepancies between samples and bulk goods, global purchasers are suggested to follow standardized verification procedures before placing large orders.
Actual production tracking data from Jinghuang shows that suppliers with complete ISO9001:2015 certification and ICP-MS testing capability can reduce product quality complaint rate to less than 0.1%, far lower than the 3.7% industry average level.
