Fused Silica Micro Powder for Precision Casting

Product Overview

This product is a high-purity fused silica micro powder specially designed for precision casting, ceramics, electronic packaging, and high-end composite materials. It is produced from ultra-pure quartz sand through high-temperature fusion and refined processing, featuring a purity of ≥99%, uniform particle size distribution (D50 0.5μm-50μm customizable), low thermal expansion coefficient, and excellent thermal stability. It significantly improves the surface finish and forming accuracy of castings.

Key Parameters

Product Advantages

• 
  High Purity & Stability: SiO₂ content ≥99%, with minimal impurities, avoiding interference during casting and ensuring consistent casting performance.
