With a consistent average SiO₂ purity of 99.74%, BRM’s High Grade Silica Sand stands among the most refined natural silica resources available in the global market. This exceptional level of purity makes it ideal for a wide spectrum of industrial and high-tech applications that demand strict chemical specifications and uniform performance.

​

The product is carefully extracted and screened to meet stringent quality standards. Laboratory analyses confirm its low contamination levels, with average trace elements measured as follows:

• Aluminum (Al): 23.44 ppm

• Calcium (Ca): 105.97 ppm

• Iron (Fe): 44.25 ppm

• Magnesium (Mg): 32.44 ppm

• Titanium (Ti): 147.12 ppm

 

These ultra-low impurity levels are essential for industries such as:

• High-performance glass manufacturing (e.g., flat glass, solar panels, fiber optics)

• Foundry applications and precision casting

• Ceramics and technical refractories

• Silicon-based chemical processing

• Filtration systems

• Construction and engineered materials

 

Beyond its chemical superiority, the silica sand’s granulometric profile provides operational flexibility and performance advantages.

 

The average particle size distribution is as follows:

• 55.05% finer than 0.106 mm

• 27.74% between 0.106 mm and 0.300 mm

• 7.29% between 0.300 mm and 0.600 mm

• 6.55% above 0.600 mm

• 3.37% ultrafine particles (<0.106 mm)

 

This natural gradation ensures enhanced compaction, optimal melting behavior, and consistent filtration rates, depending on the application.
