The particle size distribution of this product is similar to that of SFJ-PLD, which is known for its precise grading and exceptional quality. However, this product is additionally purified using a neodymium magnet to remove iron and other possible free iron compounds, ensuring the quality of colorless and transparent glass.

SFJ-PLDMO: The Pinnacle of Micronized Silica Technology for Specialized Applications
The SFJ-PLDMO, also known as premium low-iron silica, goes beyond industry standards. It is an ultra-pure silica that, in addition to being processed through SANDVIK and AKW production lines, undergoes advanced micronization. This process reduces particle size to the micron scale, resulting in a product with a high specific surface area, highly precise particle size distribution (PSD), and unique physical properties.
Through exceptional control of color-imparting impurities such as iron oxide (Fe₂O₃ < 0.025%) and titanium oxide (TiO₂ < 0.02%), this product guarantees outstanding whiteness and brightness. These characteristics make SFJ-PLDMO the ideal raw material for highly demanding industries, including paints and industrial coatings, polymer composites, advanced ceramics, and specialized sealants.
Chemical Specifications – Product Code: PLDMO
| Chemical Property | Percentage (%) | Technical Significance (Why It Matters) |
|---|---|---|
| SiO₂ (Silica) | 99.03 | Exceptional purity: ensures chemical stability, high hardness, and excellent dielectric properties in the final product. |
| Al₂O₃ (Alumina) | 0.15 | Improves mechanical properties: enhances wear resistance and strength in composites and engineering ceramics. |
| CaO (Calcium Oxide) | 0.17 | Alkalinity control: influences pH and reactivity, contributing to thermal stability and product performance. |
| Fe₂O₃ (Iron Oxide) | 0.07 | Very low iron content: critical for achieving maximum whiteness and brightness in paints, coatings, and plastics, preventing yellowing over time. |
| TiO₂ (Titanium Dioxide) | <0.02 | Precise color control: titanium is a strong pigment; maintaining it at very low levels is essential for absolute whiteness and color stability. |
