SN-FL · Low-Alpha Fused Silica Powder

SiO₂ 99.0–99.95% · Low-α Fused · D50 1–30 µm

SN-FL series Low-α Fused Silica Powder is made from low-radiation crystalline silica processed to powder by high-temperature smelting and professional equipment.

Key Features

  • ☢️ Ultra-Low α-Emission — ≤ 0.001 cph/cm² — eliminates soft errors at the source
  • 🧬 U/Th ppb-Level Control — Uranium/Thorium controlled at ppb level
  • 💾 HBM/AI Semiconductor Ready — Standard for HBM3E, DDR5, AP and high-density memory EMC
  • 🔧 Dual Grade — Crystalline SN-CL and fused SN-FL grades available
  • 🧪 High-Purity SiO₂ — 98.0–99.95 % (SN-CL crystalline / SN-FL fused)
  • 📐 Precision PSD — Customizable D50 1–30 µm
