| Item | A Grade | B Grade |
|---|---|---|
| SiO₂ | 99.9% min | 99.8% min grains; 99.7% min powder |
| Fe₂O₃ | ≤ 100 ppm | ≤ 200 ppm |
| Al₂O₃ | ≤ 200 ppm | ≤ 200 ppm |
| Na₂O | ≤ 100 ppm | ≤ 200 ppm |
| K₂O | ≤ 100 ppm | ≤ 100 ppm |
| MgO | ≤ 200 ppm | ≤ 200 ppm |
| CaO | ≤ 100 ppm | ≤ 100 ppm |
| Magnetic impurities | ≤ 50 ppm | ≤ 100 ppm |
These are typical values from the product data. Chemical composition, particle size and other limits are confirmed on the COA and the quotation before the order.
