Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Fine Particle Black Iron Oxide
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Micro-Level Perfection in Black
Deqing Demi Pigment Technology Co., Ltd. specializes in "Small-Scale Science." We recognize that for premium black products, even a few microns of grit can ruin a finish. Our fine particle black is meticulously refined to ensure a silky texture. We provide the "Deep Precision Black" that allows global brands to create iconic, high-definition products with total surface perfection and color intensity.
Fine Particle Black Usage Areas
- Magnetic Toners: Precision black for high-resolution laser printer cartridges.
- Electronics: Streak-free, deep black for high-end plastic housings.
- Luxury Paints: Smooth, reflective black for high-gloss furniture and pianos.
- Precision Inks: High-opacity, fine-grind black for security and coding inks.
Fine Black Tech Specs
| Metric | Value | Standard |

Performance Features
- Mirror-Like Gloss: Minimizes light scattering for a deep, reflective black.
- Exceptional Dispersion: Rapidly develops full color even under low-shear mixing.
- Neutral Undertone: Provides a true black without unwanted blue or green tints.
- High Purity: Low grit content protects delicate applicator heads and molds.
Q: Is this the same as Carbon Black?
A: No. It is a mineral-based magnetite. It is safer for specific industrial uses and offers better "clean-out" in production machinery.
Q: Is it heat stable?
A: It is stable up to 180∘C. For higher temperature processes, ask about our heat-stabilized series.
Industrial Performance Services
We offer "Magnetic Profile Testing," providing you with the coercivity data needed for electronic or toner applications.
Bespoke Micronization: We can mill the black oxide to your specific D90 target for ultra-thin film applications.
The Science of Ferrimagnetic Intensity
The depth of black in our fine particle magnetite is a result of "Inter-Valence Charge Transfer." In the crystal, iron exists in both Fe2+ and Fe3+ states. Electrons hop between these states, absorbing light across the entire spectrum. The science behind our fine grade lies in protecting this "Valence Balance." By ensuring the particles are small and perfectly formed, we maximize this electron hopping, resulting in an "Optical Trap" that creates a deep, infinite black.
