Low-Iron Crystalline Silica Powder for Refractories

Product Overview
Specially developed for the refractory industry, our low-iron crystalline silica powder is refined from high-purity quartz raw materials through specialized processes. With extremely low iron content and outstanding high-temperature resistance, it significantly enhances the thermal shock resistance, mechanical strength, and high-temperature stability of refractory products, making it an ideal additive for high-performance refractories.

Key Features
★ Ultra-Low Iron Content: Fe2O3 ≤ 0.05%, preventing discoloration at high temperatures
★ High Purity: SiO2≥ 99%, with minimal impurities
★ Excellent Temperature Resistance: Long-term service temperature up to 1650°C
★ Optimized Thermal Shock Resistance: Significantly improves refractory material's thermal shock resistance
★ Controllable Particle Size: Customizable D50 particle size range of 0.5-25μm

Typical Applications
• High-grade refractory bricks and unshaped refractory materials
