Chromium Oxide Green for Industrial Use
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Global Standard in Technical Green
Deqing Demi Pigment Technology Co., Ltd. is a premier manufacturer of high-purity Chromium Oxide. We recognize that in technical industries, even trace impurities can ruin a production run. Our industrial green series is produced with a focus on chemical precision, ensuring that our pigments deliver the same performance every time. We provide the "Technical-Grade" green that serves as a cornerstone for global industries from glassmaking to aerospace.
Industrial Green Usage Areas
- Glass & Ceramics: Coloring agent for green bottles and ceramic glazes.
- Metallurgy: A component in the production of metallic chromium.
- Refractory Castables: High-temp binder for furnace construction.
- Plastic Engineering: Stable color for high-performance resins (PEEK, PPS).
Chromium Green Technical Specs
| Metric | Value | Standard |
| Cr2O3 Purity | Min 99.0% | Technical Grade |
| Average Particle Size | 0.3 - 0.6 μm | Laser Diffraction |
| PH (Water Extr.) | 6.0 - 8.0 | ISO 787-9 |
| Moisture Content | Max 0.2% | ISO 787-2 |
| Total Impurities | Max 0.5% | Chemical Analysis |
Core Characteristics
- High Refractive Index: Provides exceptional opacity and brilliance.
- Thermal Inertness: Does not react with other minerals at high temperatures.
- Ultra-Low Moisture: Critical for use in moisture-sensitive plastic systems.
- Excellent Dispersibility: Rapidly integrates into liquid or powder carriers.
Q: Can this be used in food-contact plastics?
A: We offer specific high-purity grades that meet FDA/EU requirements for food-contact materials.
Q: What is the benefit of the high purity level?
A: High purity ensures that there are no "hot spots" or unwanted reactions during high-temperature ceramic firing or metal smelting.
Technical Integration Services
We offer "Purity Certification" for every lot, providing a detailed breakdown of trace elements to support your high-spec manufacturing.
Custom Jet-Milling: For glass and ceramic applications, we can provide sub-micron powders to ensure a perfectly smooth, bubble-free melt.
The Science of Isostructural Stability
Chromium Oxide Green shares an "Isostructural" relationship with Corundum (Sapphire/Ruby). This means its atoms are arranged in a nearly identical, incredibly stable hexagonal pattern. This scientific configuration is responsible for the pigment's extreme hardness and thermal resistance. In industrial use, this translates to a pigment that doesn't just "sit" in the material but adds to its structural "Toughness," making the finished product more resistant to both heat and mechanical wear.
