What is Silica Sand?
As a trusted silica sand supplier, we proudly offer high-quality silica fume, silica sand, and condensed silica fume for various industrial applications. Moreover, micro silica is a highly reactive mineral additive, consisting of ultrafine silicon dioxide (SiO2) particles. Manufacturers produce these particles, which range between 0.1 to 0.3 micrometers in diameter, as byproducts of silicon metal or ferrosilicon alloy production. Their extremely fine particle size and high reactivity make micro silica a crucial component in construction, drilling, refractory materials, and polymer composites. As a silica sand supplier, you must ensure high quality and consistent particle distribution to meet industry standards and optimize material performance across different applications.
Usage
Micro silica serves as a powerful additive across different industries due to its exceptional properties:
Increased Strength: Enhances compressive and flexural strength in concrete and composites.
Reduced Permeability: Minimizes water penetration, improving durability.
Improved Rheology: Enhances the flow properties in drilling fluids and cementitious materials.
High Thermal Resistance: Ideal for refractory applications due to its heat-resistant nature.
Enhanced Mechanical Properties: Used in polymers to improve elasticity and impact resistance.

- Bridge and Infrastructure Applications: Moreover, it is commonly used in bridge decks, highways, and marine structures, ensuring long-term durability in demanding environments.
Enhanced Workability: Available in wet and dry forms, making it suitable for both ready-mix and precast concrete applications.
3. In Refractory Materials
Micro silica plays a crucial role in the production of high-performance refractory products, offering several key benefits.
- Improved Packing Density: Specifically, it enhances the compactness of refractory castables, which in turn improves thermal resistance.
- Increased Erosion and Abrasion Resistance: Furthermore, it strengthens refractories, making them more resistant to high temperatures and harsh operating conditions.
4. Silica Sand in Polymer Composites
Micro silica is widely utilized as a reinforcing filler in the polymer industry, primarily because it significantly enhances material properties.
- Enhanced Mechanical Strength: Notably, it improves tensile strength, elasticity, and impact resistance in composite materials, making them more durable.
- Better Dimensional Stability: Moreover, it ensures long-term consistency in product shape and size, reducing deformation over time.
- Application in Automotive and Aerospace: Additionally, it is extensively used in lightweight and high-strength composite materials, which are essential for these demanding industries.
Grade and Specification of Micro Silica
Silica sand is typically classified based on both purity levels and particle sizes, as these factors determine its suitability for different applications. Specifically, the most common grades include:
- Grade 85: With 85% SiO2 content, this grade is mainly used in standard concrete and low-grade refractories.
- Grade 92: Containing 92% SiO2, this grade is particularly preferred for high-performance concrete and polymer composites.
- Grade 97: With an impressive 97% SiO2 content, this grade is best suited for ultra-high-performance applications, such as oil well cementing and advanced refractories.
Packing and Transportation of Micro Silica
Micro silica is available in multiple packaging options depending on the end-use industry:
25 kg Paper or Plastic Bags: Suitable for small-scale applications and laboratory use.
1 MT Jumbo Bags: Used for bulk industrial applications, ensuring easy handling and transportation.
Bulk Tanker Delivery: Preferred for large-scale construction and drilling operations.
