Ultra-Low Ash Semiconductor Rigid Felt for Crystal Growth Furnaces

Our semiconductor rigid felt is a purified carbon fiber composite insulation board, specifically engineered for silicon and silicon carbide crystal growth processes. It delivers ultra-low ash content (≤5 ppm), reliable thermal insulation, and high-temperature stability up to 2500°C, ensuring process purity and energy efficiency.

Key Selling Points

Ultra-low ash ≤5 ppm: Minimizes contamination in crystal growth furnaces, protecting sensitive semiconductor materials.
Low thermal conductivity 0.15-0.35 W/m·K: Provides excellent insulation, reducing energy consumption and improving temperature uniformity.
Process temperature up to 2500°C: Withstands extreme thermal conditions in inert/vacuum environments.
Bulk density 0.18-0.24 g/cm³: Lightweight yet robust structure, easy to install and maintain.
Purified PAN or rayon-based carbon rigid board: Tailored to match your furnace's hot-zone requirements.
