Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Ceramic Grade Iron Oxide Pigments
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Mastering the Chemistry of Fire
At Deqing Demi Pigment Technology Co., Ltd., we provide the "Fire-Stable" colors that the ceramic and tile industries depend on. We understand that in a kiln, chemistry is everything. Our ceramic-grade series is produced with a focus on mineralogical purity, ensuring that our pigments don't introduce unwanted fluxes or impurities that could ruin a glaze. We help our clients achieve consistent, traditional, and modern ceramic finishes that are as durable as the clay itself.
Ceramic Grade Usage Areas
- Ceramic Tiles: Body-staining and surface glazes for floor and wall tiles.
- Sanitaryware: High-purity coloring for bathroom fixtures.
- Tableware: Food-safe mineral pigments for plates and bowls.
- Art Pottery: Specialized oxides for unique decorative glaze effects.
Ceramic Grade Technical Specs
| Metric | Value | Standard |
| Heat Stability | Up to 1300∘C | Internal Method |
| Iron Content (Fe2O3) | Min 98.5% | Chemical Analysis |
| Loss on Ignition | Max 0.2% | ISO 787-2 |
| Residue on 325 Mesh | Max 0.01% | ISO 787-7 |
| Acid/Alkali Resistance | Extreme | Glaze Standard |
Performance Attributes
- Non-Reactive: Does not cause pinholing or "crawling" in glazes.
- Consistent Reduction: Provides predictable results in both oxidation and reduction firing.
- Intense Opacity: Effective at masking the underlying clay color.
- Heavy Metal Safety: Low-solubility grades suitable for lead-free glaze systems.
Q: Will these pigments change color at Cone 6 or Cone 10?
A: Our ceramic reds are stable up to Cone 8; for higher temperatures, we recommend our specialized calcined brown and black series.
Q: Can they be used for "Underglaze" painting?
A: Yes, their ultra-fine particle size makes them ideal for detailed decorative work under a transparent glaze.
Glaze Formulation Consulting
We provide "Firing Shrinkage Analysis," ensuring that the addition of pigment doesn't alter the "fit" of the glaze to the ceramic body.
Custom Frits: We can collaborate with manufacturers to develop pre-reacted pigment-frit combinations for specialized industrial tile production.
The Science of Thermal Phase Shift
In ceramics, we focus on the "Redox State." Iron oxide can exist as Fe2O3 (Red) or Fe3O4 (Black) depending on the kiln atmosphere. We optimize the crystal structure of our ceramic pigments to be "Phase-Stable," meaning they resist unwanted oxidation or reduction transitions during the cooling cycle. This ensures that the red you see when you load the kiln is the red you see when you unload it, providing the industrial-scale reliability needed for large-format tile manufacturing.
