Silica Sand – Precision-Graded for Industry
Asteroid Microns Silica Sand is processed from high-purity quartz (SiO₂), carefully washed and graded into precise particle sizes.
It is known for its high melting point, hardness, and chemical stability, making it essential across industries from glass manufacturing to construction.
Key Characteristics
- High SiO2 Content: Minimal iron and alumina impurities ensure superior clarity and heat resistance.
- Sub-Angular to Rounded Grains: Optimized grain shapes for better flow and bonding in foundry and construction applications.
- Thermal Stability: Withstands extreme temperatures without losing structural integrity.
- Chemical Inertness: Non-reactive with most acids and alkalis, making it a stable filler.

Versatility Across Industries
| Industry | Primary Use | Key Benefit |
|---|---|---|
| Glass Manufacturing | Container & Flat Glass | Provides the essential silica required for clarity, strength, and durability. |
| Foundry & Casting | Sand Casting Molds | High fusion point (1700°C) and low thermal expansion ensure precise metal castings. |
| Construction | Mortars & Grouts | Improves structural density and provides a slip-resistant texture in flooring. |
| Water Filtration | Multi-media Filters | Uniform grain size efficiently traps contaminants in municipal and industrial water systems. |
| Ceramics | Glazes & Bodies | Provides the structural “skeleton” for ceramic products and improves glaze finish. |
Pro Tip: For Epoxy Flooring and Construction Chemicals, the moisture content of silica sand is critical. Using our Kiln-Dried Silica Sand ensures that the moisture doesn’t interfere with the chemical curing process of the resins, preventing bubbles and delamination in the final surface.
Applications
Why Choose Asteroid Microns Silica Sand?
- Sophisticated Washing Process: Our multi-stage water washing removes clay, silt, and organic matter, resulting in a cleaner, more efficient product.
