TECHNICAL SPECIFICATIONS
Chemical Composition
| Component | Abrasive Grade (Primary) | Refractory Grade | Blasting Grade |
|---|---|---|---|
| Al₂O₃ | ≥95% | ≥94% | ≥95% |
| SiO₂ | ≤1.5% | ≤1.8% | ≤1.5% |
| Fe₂O₃ | ≤0.3% | ≤0.5% | ≤0.3% |
| TiO₂ | 1.5-3.8% | 2.0-3.5% | 1.5-3.0% |
| CaO + MgO | ≤0.5% | ≤0.6% | ≤0.5% |
Grain Size Distribution
- Macro Grits (Abrasive/Blasting): F4-F220 (e.g., F16: 1.00-1.40 mm; F120: 0.09-0.13 mm)
- Micro Grits (Polishing): P12-P220 (e.g., P100: 0.11-0.15 mm)
- Refractory Sizes: 0-1 mm, 1-3 mm, 3-5 mm, 5-8 mm, or custom sections (e.g., 100# for fine powders)
- Particle Distribution: Uniform, tested via laser particle size analyzer to ensure <5% deviation from specified range.
Customization: Tailored sizes for regional preferences, such as finer grits for Southeast Asian precision manufacturing or coarser for Middle Eastern oil & gas blasting.
