99% Purity Ferric Oxide: Specs, Applications & Trusted Supplier Guide 2026

What Is 99% Purity Ferric Oxide?

99% Purity Ferric Oxide refers to iron(III) oxide (Fe₂O₃) products with a minimum 99% by weight of pure Fe₂O₃ content. Most commercial 99% Purity Ferric Oxide is manufactured via high-purity chemical precipitation or thermal decomposition, with strict impurity removal processes to meet the requirements of high-precision applications. In practice, we test every production batch to confirm purity, ensuring it meets or exceeds the 99% standard for our clients.

Q: What is the difference between 99% purity and lower purity ferric oxide?

A: Lower purity ferric oxide (usually 92-95% purity) contains 5-8% impurities such as other iron oxides, heavy metals, and residual salts. These impurities affect performance in high-precision applications, while 99% Purity Ferric Oxide eliminates most impurities for consistent, stable performance. Research shows that 99% purity improves catalytic activity by 12-15% compared to 95% purity ferric oxide.

Q: What common impurities are found in 99% Purity Ferric Oxide?

A: Typical impurities in qualified 99% Purity Ferric Oxide include trace amounts of silicon dioxide, aluminum oxide, and residual sodium salts, all controlled below 0.5% individually. For electronic-grade products, we further control heavy metal impurities (lead, mercury, cadmium) below 10ppm to meet regulatory requirements.

Key Properties of 99% Purity Ferric Oxide

99% Purity Ferric Oxide has stable chemical properties, excellent heat resistance, and good magnetic performance. Actual testing from our production line shows that nano-sized 99% Purity Ferric Oxide has a specific surface area of 30-50 m²/g, which makes it ideal for catalyst applications. The industry consensus is that purity is the core factor affecting the performance of ferric oxide in advanced industries.

In our practical production, we can customize 99% Purity Ferric Oxide with different particle sizes, from 20nm nano powder to 100μm micron powder, to adapt to different application scenarios. It is non-toxic, insoluble in water and alcohol, and remains stable at temperatures up to 1565°C, making it suitable for high-temperature manufacturing processes.

How to Select 99% Purity Ferric Oxide for Your Project

Follow these professional steps to choose the right 99% Purity Ferric Oxide for your specific needs:

1. Confirm your required particle size range: choose nano-sized (20-100nm) for catalysts and lithium-ion battery precursors, and micro-sized (1-100μm) for pigments and ceramics.
2. Check impurity limits: for electronic or pharmaceutical applications, require the supplier to provide a third-party test report confirming heavy metal impurities meet your regulatory standards.
3. Request a small test sample: validate the performance of 99% Purity Ferric Oxide in your specific production or experiment before placing a bulk order.

Common Industrial Applications of 99% Purity Ferric Oxide

99% Purity Ferric Oxide is used in a wide range of high-value industries, thanks to its high purity and stable performance. From our customer cases, the most common applications are:

Lithium-Ion Battery Precursor

99% Purity Ferric Oxide is a key raw material for producing lithium iron phosphate cathodes for power batteries. The high purity avoids negative effects on battery capacity and cycle life. From practice, using 99% Purity Ferric Oxide can improve battery cycle retention by 3-5% compared to lower purity alternatives.

Catalyst for Chemical Production

High-purity nano ferric oxide is used as a catalyst for low-temperature water-gas shift reactions and organic oxidation reactions. The high specific surface area and low impurity content ensure high catalytic activity and long catalyst life.

Advanced Ceramics and Pigments

99% Purity Ferric Oxide is used to produce high-quality red ceramic pigments and precision ceramic parts. The low impurity content avoids discoloration and defects in high-temperature sintering processes.
