White Microsilica
HSA supplies high-purity Білий кремнеземний дим specially developed for refractory, керамічний, and advanced material applications where low impurities and high whiteness are required. Our product range includes ZSF94 (94% SiO₂, Zirconia Grade), 98Р. (98% Densified), and 98U (98% Undensified) to meet different processing and performance requirements.
- ZSF94 (Zirconia Grade): Contains approximately 94% SiO₂ with zirconia content, making it ideal for zircon-based refractories, investment casting, and high-temperature ceramic applications.
- 98Р. (Densified): High-purity densified white silica fume with improved bulk density for cost-effective transportation, storage, and automated handling.
- 98U (Undensified): High-purity undensified white silica fume with ultra-fine particle distribution, providing excellent dispersion and maximum pozzolanic and filling performance.
With consistent quality, low impurity levels, and strict quality control, HSA White Silica Fume helps improve density, сила, thermal stability, and durability in demanding industrial applications. Customized packaging and worldwide shipping are available to meet customers’ specific requirements.

Додатки
- High-Performance Concrete: White microsilica is used to produce high-performance concrete with improved strength, durability, and resistance to chemical attack.
- Refractory Materials: Due to its high purity and low iron content, zirconium silica fume is an essential ingredient in the production of refractory materials such as bricks, castables, and monolithic linings.
- White Cement: White microsilica is used to produce high-purity white cement, which has applications in architectural and decorative concrete.
- Ceramics: Zirconium silica fume is used in the production of advanced ceramics, such as zirconia-based ceramics, where it can act as a sintering aid and enhance the final properties of the product.
- Repair Materials: White microsilica can be used in repair materials to improve bonding, сила, and durability.
- Oil Well Cementing: Zirconium silica fume can be added to oil well cement to enhance its performance by improving its mechanical properties, reducing permeability, and increasing resistance to chemical attack in the harsh downhole environment.
- Precast Concrete: White microsilica can be used in the production of precast concrete elements, where it contributes to improved strength, durability, and surface finish.
- Shotcrete and Gunite: Zirconium silica fume can be added to shotcrete and gunite mixtures to enhance their strength, adhesion, and resistance to cracking, making them suitable for applications in tunneling, mining, and slope stabilization.
- Self-Compacting Concrete (SCC): White microsilica’s ability to improve workability and rheological properties makes it suitable for use in self-compacting concrete, which requires minimal vibration and compaction during placement.
- Fiber-Reinforced Concrete: The addition of zirconium silica fume to fiber-reinforced concrete can enhance the bond between fibers and the cementitious matrix, leading to improved mechanical properties and durability.
