Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Green Iron Oxide for Ceramic Coloring
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Permanent Green of the Ceramic Arts
Deqing Demi Pigment Technology Co., Ltd. provides the ceramic industry with "Kiln-Proof Green." We recognize that in ceramic production, the pigment must survive the fire. Our ceramic-grade green is manufactured with ultra-low impurity levels to ensure glaze clarity and brilliance. We provide the "Inorganic Confidence" that allows industrial tile makers and studio potters to achieve deep, permanent greens that never fade or "burn out."
Ceramic Green Usage Areas
- Glaze Stains: Producing vibrant, stable greens for pottery and tableware.
- Wall Tiles: Consistent green coloration for high-fire porcelain bodies.
- Sanitary Ware: Durable, chemical-resistant green for bathroom fixtures.
- Roofing Granules: High-heat stable color for ceramic-bonded roof grains.
Ceramic Green Technical Specs
| Metric | Value | Standard |
| Cr2O3 Content | Min 99.0% | Chemical Analysis |
| Heat Resistance | Up to 1500∘C | Melting Point Test |
| Moisture Content | Max 0.2% | ISO 787-2 |
| Sieve Residue (325 mesh) | Max 0.1% | ISO 787-7 |
| Hardness (Mohs) | 8 - 8.5 | Mineral Standard |
Core Advantages
- Absolute Heat Stability: Will not change color even at the highest firing ranges.
- Exceptional Hardness: Adds durability and scratch resistance to the glaze surface.
- Acid & Alkali Resistant: Immune to the corrosive effects of kiln gases and cleaning chemicals.
- Zero Bleeding: Maintains sharp edges in underglaze and silk-screen decorations.
Q: Is this the same as "Chrome Green" used in paints?
A: It is the high-purity oxide form, specifically refined to be safe and stable for high-temperature ceramic use.
Q: Does it affect the glaze melt?
A: No, it is highly refractory and acts as a stable suspension within the molten glaze.
Ceramic R&D Services
We offer "Compatibility Testing," ensuring our green oxide integrates perfectly with your specific frit and flux package.
Custom Micronization: We can provide ultra-fine green oxides for precision inkjet printing on ceramic tiles.
The Science of Refractory Cation Bonding
The green in Cr2O3 is a result of the "d-d electronic transitions" of the Chromium ion within an octahedral oxygen lattice. The science behind our ceramic grade lies in "Lattice Rigidity." Because Chromium Oxide has a melting point of 2435∘C, it is physically impossible for the color to break down in a standard ceramic kiln. This scientific "Thermal Shielding" ensures that the green you apply to the clay is the exact green that emerges from the fire, providing unparalleled color security.
