What Is Nano Iron Oxide: Core Definition & Basic Properties
Nano Iron Oxide refers to ultra-fine iron oxide particles with diameter ranging from 1nm to 100nm. It has unique magnetic, optical and catalytic properties that traditional micron iron oxide cannot achieve. In practice, Jinghuang Technology has been optimizing the particle size distribution and dispersion performance of this product for 8 years to meet diversified industrial requirements.
Q: What are the key physical properties of qualified Nano Iron Oxide?
Actual test shows that standard high-quality Nano Iron Oxide from regular suppliers has 99%+ purity, narrow particle size distribution, no obvious agglomeration after long-term storage, and stable chemical performance under normal temperature and pressure. The specific surface area can reach up to 80 m²/g for 20nm grade products.
Q: What is the difference between Nano Iron Oxide and common iron oxide powder?
From practical application cases, Nano Iron Oxide has 15-30 times higher specific surface area than common iron oxide, significantly enhanced catalytic activity, superparamagnetic characteristics for grades below 30nm, and better ultraviolet shielding effect used in coating and rubber products.
Follow the 3-step workflow below to verify the quality of Nano Iron Oxide before bulk purchase to avoid unqualified products:
- Conduct XRD phase analysis to confirm no extra impurity peaks in test results
- Use BET specific surface area analyzer to check if the data matches the product specification sheet
- Run 2-hour dispersion test in your target solvent to measure the agglomeration rate below 5%

Q: What is the normal lead time for bulk Nano Iron Oxide order in 2026?
For standard grades, Jinghuang Technology keeps 3-5 tons of inventory in warehouse to support 3-7 days domestic delivery, and 7-15 days global air/sea shipping service for overseas clients. Custom modified products usually take 15-20 working days for production.
Safe Handling & Storage Rules for Nano Iron Oxide
Nano Iron Oxide is low-toxic material, but proper operation procedure is still required to avoid unnecessary safety risks in daily production use.
Q: What personal protection measures should be taken when handling Nano Iron Oxide powder?
Operators need to wear N95 face mask, nitrile gloves and protective goggles to avoid long-term inhalation of nano powder or direct contact with eyes and skin. In case of accidental contact, rinse with plenty of clean water immediately.
Q: What is the correct long-term storage method for Nano Iron Oxide?
Seal the product package tightly, store in cool and dry environment below 30℃, keep away from strong acidic materials and open fire to prevent unnecessary chemical reaction. The shelf life of properly stored products can reach 24 months.
