Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Synthetic Black Metal Oxide Pigments
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Precision Black for Global Industry
Deqing Demi Pigment Technology Co., Ltd. is a specialist in synthetic black technology. We recognize that for industrial users, "Black" is not just a color—it's a technical specification. Our synthetic black series is produced using a controlled precipitation process to ensure uniform magnetic and physical properties. We provide the "Industrial Strength Black" that allows our clients to manufacture everything from high-strength concrete to high-precision printer toners.
Synthetic Black Usage Areas
- Magnetic Toners: Precision black for laser printer and copier cartridges.
- Plastic Compounding: UV-stable black for high-durability polymer parts.
- Concrete & Paving: Deep black for architectural masonry and asphalt.
- Industrial Inks: High-opacity black for coding and marking systems.
Synthetic Black Technical Specs
| Metric | Value | Standard |
| Fe3O4 Content | Min 90% - 95% | ISO 1248 |
| Oil Absorption | 15 - 25 g/100g | ISO 787-5 |
| Specific Surface Area | 8 - 15 m²/g | BET Method |
| Sieve Residue (325 mesh) | Max 0.2% | ISO 787-7 |
| Tinting Strength | 100% ± 3% | ISO 787-24 |
Performance Characteristics
- High Magnetic Susceptibility: Controlled magnetic properties for technical applications.
- Total Opacity: Provides maximum hiding power for thin-film applications.
- UV/Weather Resistant: Will not fade or chalk in exterior environments.
- Alkali Stable: Fully compatible with cement and lime-based systems.
Q: Can this black oxide be used in high-heat plastics?
A: It is stable up to 180∘C. For processes exceeding this, we recommend our heat-stabilized black series to prevent oxidation to brown.
Q: Is it "cleaner" than natural magnetite?
A: Yes, it is free from abrasive silica and heavy metal impurities found in mined ores, protecting your machinery from wear.
Industrial Performance Services
We offer "Magnetic Profile Testing," providing you with the coercivity and saturation data needed for electronic or toner applications.
Custom Dispersion Grades: We can provide black oxides optimized for rapid wetting in both water-borne and solvent-borne systems.
The Science of Octahedral Geometry
The performance of synthetic black oxide is rooted in "Particle Morphology." During the precipitation phase, we control the crystal growth to favor "Octahedral" structures. The science behind this is that octahedral crystals pack more efficiently and reflect light more uniformly than irregular natural particles. This resulting uniformity is what gives our synthetic black its superior "Tinting Efficiency" and predictable magnetic behavior, making it a high-performance material for both decorative and technical engineering.
