This product is the result of the crushing line operation on the raw mineral. The crushing line, consisting of jaw crushers, vertical shaft crushers, and cone crushers, along with a four-deck screening system and associated conveyor belts, produces a material with a particle size range of 0 to 2 mm.
While this is primarily intended as feed for the wet processing line, it can also be used directly in industries such as AAC (autoclaved aerated concrete), artificial stone, and abrasive manufacturing.
Purchase of Cristobalite Silica (SFJ-CRA)
SFJ-CRA: Absolute Whiteness, Exceptional Durability
Cristobalite silica (SFJ-CRA) is a polymorphic form of silica produced from ultra-pure quartz at very high temperatures (above 1470 °C). This advanced calcination process, carried out at Pars Kansar Silica Plant using state-of-the-art technology, creates a unique crystalline structure that imparts outstanding optical and physical properties to the product.
SFJ-CRA is more than just a white filler; it is an engineered additive that transforms the performance of your final product. Its high hardness, excellent thermal and chemical stability, and low refractive index make it an unmatched choice for industries seeking the highest levels of quality and aesthetic appeal.
Technical Specifications and Chemical Analysis
The following table demonstrates why SFJ-CRA is considered a premium product.
Chemical Specifications – Product Code: CRA
| Chemical Property | Percentage (%) | Technical Significance (Why It Matters) |
|---|---|---|
| SiO₂ (Base Silica) | 98.00 | Exceptional purity: ensures chemical stability and does not negatively affect your formulation. |
| Al₂O₃ (Alumina) | 1.02 | Structural reinforcement: enhances mechanical strength and product stability in industrial processes. |
| CaO (Calcium Oxide) | 0.26 | Alkalinity control: influences reactivity and chemical stability of the product. |
| Fe₂O₃ (Iron Oxide) | 0.07 | Prevents yellowing: low iron content ensures maximum whiteness and clarity in the final product. |
| Whiteness (L) | >95 | Exceptional whiteness: allows production of pure white and vivid colors with minimal use of expensive pigments such as TiO₂. |
| Hardness (Mohs) | 6.5 – 7 | Excellent abrasion resistance: increases scratch, wear, and wash durability in paints, coatings, and composite surfaces. |
