The particle size of this product ranges from 0.09 to 0.4 mm, featuring a precise particle size distribution and exceptional quality, making it one of the purest and finest silica products produced in Iran.
Chemical analysis results indicate a SiO₂ purity of 99.2%, making it suitable for specialty applications such as opal glass, borosilicate (Pyrex), and crystal glass production.
Purchase of Premium Low-Iron Silica for Crystal and Opal Glass Industry
SFJ-PLD: The Gold Standard of Silica for Unmatched Transparency
The SFJ-PLD, a premium low-iron silica, is the flagship product of kansar Silica Processing Company. It is produced by combining the finest Iranian silica ores and stones with state-of-the-art European processing technologies. For this special silica, the SANDVIK crushing line (Sweden) and AKW wet processing line (Germany) are employed, resulting in completely uniform particle size and stable chemical analysis. These characteristics ensure the quality of your final products and strengthen the trust of various industries in this premium silica.
With SiO₂ purity exceeding 99% and carefully controlled Fe₂O₃ (iron oxide) below 0.053%, SFJ-PLD silica eliminates unwanted color tints (such as green or yellow). This ensures maximum transparency and brilliance in crystal glass, opal glass, and pharmaceutical glassware. Therefore, this product is the ideal choice for leading glass manufacturers seeking export-quality products, analytical stability, and a competitive edge in the global market.
Due to its high quality, stable characteristics, and precise particle size, SFJ-PLD holds a special position not only in the crystal and opal glass industry but also in other sensitive industrial applications. Choosing this product guarantees quality, enhances customer trust, and ensures optimal results in final production.
Chemical Specifications – Product Code: PLD
| Chemical Property | Percentage (%) | Technical Significance (Why It Matters) |
|---|---|---|
| SiO₂ (Silica) | 99.01 | High purity: the main component of glass. High purity ensures exceptional clarity and minimizes melting loss in luxury glass production. |
| Al₂O₃ (Alumina) | 0.93 | Increases durability: enhances chemical and mechanical resistance for longer-lasting glass. |
| CaO (Calcium Oxide) | 0.35 | Efficient fluxing: acts as a flux, lowering furnace temperature and improving melting efficiency. |
| Fe₂O₃ (Iron Oxide) | 0.053 | Extremely low iron: critical to prevent unwanted green/yellow coloration. |

Summary and Notes
Sample Type: Silica Sand
Sample Code: PLD
Column Explanation:
Mesh (Mesh No.): Sieve mesh number.
Size (mm): Particle diameter in millimeters.
Size (µm): Particle diameter in microns.
Sample (%): Weight percentage remaining on each sieve (partial distribution).
Cumulative (%): Cumulative weight percentage passing through each sieve.
Important Note:
The “Total (%)” column in the original image is labeled as “Sample,” but based on the values, it represents Cumulative Passing (%). This indicates the percentage of the total sample that has passed through the corresponding sieve. For example, 84.6% of the total sample passes through the Mesh 80 sieve.
