What are shaped products made of inorganic ceramic fiber? What are their key characteristics?

Shaped products made of inorganic ceramic fiber are customized refractory and thermal insulation products manufactured from inorganic non-metallic materials such as alumina (Al₂O₃) and silica (SiO₂) through high-temperature melting, fiber spinning, and molding processes. Their key characteristics include:

1. High Temperature Resistance: Temperature range up to 550℃–1600℃, depending on the material composition (e.g., alumina-based, zirconia-containing).

2. Lightweight and Low Thermal Conductivity: Bulk density as low as 96–160 kg/m³, thermal conductivity only 0.03–0.25 W/m·K, significantly superior to traditional refractory bricks.

3. Chemical Stability: Resistant to corrosion from acids, alkalis, and salts (except hydrofluoric acid and strong alkalis), suitable for corrosive environments such as chemical and metallurgical industries.

4. Customizability: Supports vacuum forming into complex shapes (e.g., tubular, conical, dome-shaped), meeting special requirements for industrial furnaces, spacecraft thermal protection, and other applications.
