Ceramic Grade Iron Oxide Pigment Numbers
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Precision Numbers for Ceramic Innovation
At Deqing Demi Pigment Technology Co., Ltd., we provide the numerical clarity required for ceramic excellence. We recognize that in tile and pottery production, a change in iron purity can ruin an entire kiln load. Our ceramic-grade numbering system is designed for total transparency. We provide the "Standardized Data" that allows industrial ceramicists to maintain perfect color consistency across millions of square meters of tiles.
Ceramic Number Usage Areas
- Industrial Tiles: Standardized numbers for mass-market floor and wall tiles.
- Body Stains: Identifying codes for "Through-Body" coloring of porcelain.
- Glaze Chemistry: Specific iron numbers for calculating molecular glaze formulas.
- Frit Manufacturing: High-purity iron codes for producing color-stable glass frits.
Ceramic Grade Identification
| Code Series | Fe2O3 Purity | Primary Use |
| Series 900 | 90 - 95% | Brick/Heavy Clay |
| Series 950 | 95 - 98% | Glazes/Body Stains |
| Series 990 | 99%+ | Electronics/Fine Porcelain |
| Series M (Milled) | D50 < 1.0 μm | Fine Decoration |
Performance Features
- Thermal Consistency: Numbers correspond to pigments with proven stability up to 1250∘C.
- Predictable Reactivity: Known iron-to-silica ratios for precise glaze calculation.
- Low Carbon Profile: Prevents "Pin-holing" and "Black-coring" in fired ceramic bodies.
- High Surface Area: Optimized numbers for rapid dissolution in molten glazes.
Q: What does the "L" or "H" suffix mean on your ceramic numbers?
A: "L" stands for Low-purity (Economy) and "H" for High-purity (Premium) applications.
Q: Can I use Number 990 for magnetic ceramics?
A: Yes, the 99%+ purity series is ideal for manufacturing soft ferrites and electronic ceramic components.
Technical Documentation Services
We offer "Molecular Weight Certificates," providing the exact iron-to-oxygen ratio of your specific batch for precise laboratory formulations.
Custom Sieve Numbers: We can process ceramic iron to your specific mesh requirements, such as -200 or -325 mesh, for consistent glaze texture.
The Science of Pyrometric Performance
The "Numbers" in ceramic oxides reflect the pigment's "Phase Stability." During firing, iron oxide can transition from Hematite (Fe2O3) to Magnetite (Fe3O4) depending on the kiln atmosphere. Our numbering system categorizes pigments by their "Decomposition Threshold." High-numbered grades are treated to resist reduction, ensuring the iron remains in its trivalent state for red colors, or predictably reduces for deep blacks, providing the scientific control needed for repeatable ceramic results.
