Key Applications of Quartz Powder in the Electronics and Information Technology Sector

Quartz powder, a finely ground form of silicon dioxide (SiO2), plays a critical role in modern electronics and IT infrastructure. Its unique properties—including high thermal stability, electrical insulation, and chemical inertness—make it indispensable for advanced technologies. Below, we explore its key applications and highlight how our MW Ultrafine Grinding Mill ensures superior quartz powder production.

1. Semiconductor Manufacturing

Quartz powder is a foundational material in semiconductor fabrication. It is used in:

  • Wafer Polishing: Ultra-fine quartz powder (d97 ≤5μm) ensures mirror-smooth surfaces for silicon wafers.
  • Insulating Layers: Its dielectric properties make it ideal for isolating microelectronic components.

2. Optical Fiber Production

High-purity quartz powder is essential for manufacturing low-loss optical fibers. Our MW Ultrafine Grinding Mill achieves the required fineness (325–2500 meshes) with minimal iron contamination, critical for signal clarity.

3. Printed Circuit Boards (PCBs)

Quartz powder reinforces epoxy resins in PCBs, enhancing:

  • Thermal resistance (up to 1,000°C).
  • Mechanical strength for high-density circuits.
