Several standard sizes are available, and particle size can be made to the customer’s requirement.
Chemical composition
| 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.
B grade powder is typically quoted at SiO₂ 99.7% min, and B grade grains at 99.8% min. A grade is typically 99.9% min. The lot COA is the document to check.
