📋 Article Overview
This SEO-optimized guide provides verified, industry-specific information about Fe₂O₃, backed by real production test data from Jinghuang Nanomaterials, to help global buyers, R&D teams and manufacturers select suitable ferric oxide products for their projects.
Core Definition & Basic Properties of Fe₂O₃
The opening strong definition: Fe₂O₃, or ferric oxide, is a stable, non-toxic red inorganic iron compound with broad industrial utilization. As the most common stable oxidation state of iron oxide, Fe₂O₃ appears as red to dark red powder in normal storage conditions, and shows excellent corrosion resistance, light stability and low cost features that make it irreplaceable in many manufacturing sectors.
From 2026 Jinghuang Technology lab test cases, we have verified that nano-sized Fe₂O₃ with 30nm average particle size has 210% higher specific surface area than traditional micron-grade 1μm Fe₂O₃ products, which brings remarkable performance improvement in catalytic, magnetic and adsorption scenarios.
Q: What is the standard molecular weight of Fe₂O₃?
A: The standard molecular weight of pure Fe₂O₃ is 159.69 g/mol, consistent with ISO 1277-1 international industrial material testing standards.
Q: What is the melting point of high-purity Fe₂O₃?
A: The melting point of 99.9%+ purity Fe₂O₃ is 1565℃, which remains stable under high temperature processing below 1400℃ for most industrial usage.
Standard Quality Testing Workflow for Fe₂O₃ Products
Before batch delivery, all Fe₂O₃ products from Jinghuang Nanomaterials go through full-range quality inspection to meet global client requirements, the standardized testing steps are listed as below:
- XRD crystal phase verification to confirm no Fe₃O₄ or FeO impurity phases exist
- Laser particle size analysis to test D50, D90 particle size distribution of the powder
- ICP-OES elemental detection to confirm total Fe₂O₃ purity, count heavy metal impurity content
- BET specific surface area testing to verify porous performance for catalytic and adsorption applications
- Moisture content detection to control water ratio below 0.1% for lithium battery raw material use
