SN-RG · Fused Angular Silica Powder

SiO₂ 99.0–99.95% · Expansion 0.5×10⁻⁶ · Fused Angular

SN-RG series Fused Silica Powder is made from high-purity crystal silica by electrically fusing to amorphous silica, then processed by sorting, ball milling and air classifying into amorphous SiO₂ powder.

Key Features

  • 💎 High Strength & Wear Resistance — Angular structure maximizes mechanical properties of composites
  • 🔧 Dual Grade Lineup — Choice of fused SN-RG and crystalline SN-JG
  • 🧪 High-Purity SiO₂ 98.0–99.95% — Low-iron/low-alkali control ensures insulation reliability
  • ⚙️ Wide PSD Range — Custom D50 from 1 to 45 µm available
  • 💰 Cost-Effective — Standard filler with lower cost than spherical grades
  • 🔥 Thermal Stability — Maintains properties under high-temperature processes
