Core Advantages
Ultra-High Purity: SiO2 content ≥99%, with extremely low impurity levels, ensuring product stability and reliability. Excellent Whiteness: Unique processing technology delivers significantly higher whiteness than ordinary silica powder, making it ideal for applications with strict color requirements. Controllable Particle Size: D50 range of 0.5μm-50μm (customizable), with concentrated particle size distribution and excellent flowability. Outstanding Performance: Low thermal expansion coefficient, high insulation resistance, high-temperature resistance (>1600°C), and strong chemical inertness.
