Why Does Silica Micro Powder (Ultrafine Quartz Powder) Need Surface Modification?

By

Silica micro powder—also known as ultrafine quartz powder, fused silica powder, or crystalline silica powder—is produced from high-purity quartz through crushing, classification, and purification. The particle size typically ranges from 1–45 μm, with SiO₂ content between 99.5% and 99.99%. Silica micro powder surface modification plays a crucial role in enhancing compatibility and performance in downstream

How to Prepare High-Sphericity Silica Micro-powder from Quartz Powder?

By

High-sphericity silica micro-powder (sphericity ≥ 0.95, often called spherical SiO₂) is an essential functional powder in advanced fields such as 5G substrates, copper-clad laminates (CCL), EMC epoxy molding compounds, silicone adhesives, and thermal interface materials. Traditional quartz powder produced by mechanical crushing has irregular angular shapes. Direct use leads to high system viscosity, low filling
