Ceramic Fiber Products | High-Temperature Industrial Insulation Solutions
Heat resistant up to 1600°C · 40% energy savings · OEM/ODM customization available upon request.

Ceramic fiber products are a type of inorganic, non-metallic, high-temperature resistant material made primarily from alumina (Al₂O₃) and silica (SiO₂). They are produced through high-temperature melting followed by blowing or spinning processes to form fibers. The fibrous structure endows these materials with unique properties, making them widely used in high-temperature insulation, fire protection, and energy-saving applications.

Basic Composition and Production Process of Ceramic Fiber Products

Composition:

• Base Formula: Al₂O₃ (40–60%) + SiO₂ (40–60%), with optional addition of zirconia (ZrO₂) to enhance temperature resistance.

• High-Purity Variant: Al₂O₃ content >72% (e.g., zirconia-containing ceramic fiber), capable of withstanding temperatures above 1600°C.

Production Process:

• Melt-Blown Method: Raw materials are melted at high temperature and then blown into fibers (diameter 3–5μm) using high-speed airflow.

• Spun Fiber Method: Fibers are formed via centrifugal spinning, producing longer and more uniform fibers with higher tensile strength.

• Secondary Processing: The fibers are further processed through needling, layering, or vacuum forming into various shapes such as blankets, modules, and papers.
