Material Composition Differences

Traditional Ceramic Fiber Blankets

Conventional ceramic fiber blankets primarily consist of alumina-silicate fibers, typically containing aluminum oxide (Al₂O₃) and silicon dioxide (SiO₂) in varying proportions. These refractory blankets have served industrial applications for decades, providing reliable thermal insulation at temperatures ranging from 1000°C to 1400°C. However, traditional ceramic fiber blankets contain potentially hazardous substances that raise health and environmental concerns.

The fibrous structure of conventional materials includes refractory ceramic fibers (RCF) classified as potentially carcinogenic by international health organizations. These fibers demonstrate high bio-persistence, meaning they resist dissolution when inhaled into the human respiratory system, potentially leading to long-term health complications.
