Aluminum silicate fiber

Ceramic fiber board is a high-temperature insulation material made from aluminosilicate ceramic fibers formed into a rigid structure. With excellent thermal stability, low thermal conductivity, and superior mechanical strength, ceramic fiber board is widely used in industrial furnaces, kilns, reactors, metallurgy, and thermochemical processing systems.
As a premium refractory material, ceramic fiber board helps reduce energy loss, improve furnace efficiency, extend equipment lifetime, and offer stable performance under continuous high-temperature operation.

What Is Ceramic Fiber Board?

Ceramic fiber board is manufactured by vacuum-forming ceramic fibers, binders, and fillers into a rigid, lightweight structure. Compared with ceramic fiber blanket or ceramic fiber paper, the board type offers higher compressive strength, better dimensional stability, and long-term heat resistance.

Key Features

High temperature resistance up to 1260°C – 1600°C
Low thermal conductivity and excellent insulation efficiency
High mechanical strength and rigidity
Excellent resistance to thermal shock
Non-combustible and chemically stable
Easy to cut, shape, and install
Low shrinkage at elevated temperatures
Environment-friendly, asbestos-free material

Types of Ceramic Fiber Boards

Ceramic fiber boards are available in multiple grades depending on the temperature rating and density:

1. Standard Ceramic Fiber Board (1260°C)

Ideal for general insulation, kiln linings, furnace doors, and fireproof partitions.

2. High-Purity Ceramic Fiber Board (1350°C)

Made with high-purity aluminosilicate fiber, suitable for higher-temperature industrial applications.

3. High-Aluminum Ceramic Fiber Board (1430°C)

Includes higher alumina content, providing superior thermal stability and creep resistance.

4. Zirconium-Enhanced Ceramic Fiber Board (1600°C)

Used in extreme high-temperature environments such as petrochemical furnaces, casting, and advanced thermal processing equipment.
