Home Refractory Ceramic Fiber (RCF) Ceramic Fiber Board

Ceramic Fiber Board

Ceramic Fiber Board is made by using ceramic fiber and a little binding agent through vacuum forming. Ceramic fiber board can maintain its mechanical strength after high-temperature heating. OSYMEN ceramic fiber board can resist the scouring of airflow for its high strength, so it can be the material of internal linings.
The usability of hydrophobic ceramic fiber board is really good under the condition of high moisture. Ceramic fiber board has excellent hydrophobicity after processing by specific techniques.


Hardening ceramic fiber board
is a high hardness of refractory fiber board, there are three types of products with surface hardening, severe hardening and soaking hardening, which can be used in high mechanical strength requirements of the thermal equipment.

Ceramic Fiber Board

 

Ceramic fiber board are a critical component in thermal management and insulation, especially in high-temperature environments. Here’s an overview of their properties, production process, applications, and advantages:

Properties of Ceramic Fiber Boards

  1. Composition: Ceramic fiber boards are made from high-purity aluminosilicate materials. Their chemical composition is mainly alumina (Al2O3) and silica (SiO2), with alumina constituting about 47% of the composition​​.
  2. Thermal Properties: These boards can handle continuous temperatures up to 1,800°F, and maximum temperatures of around 2,300°F. They have low thermal conductivity and a specific heat of 0.27 Btu/lb°F at 2000°F​​​​.
  3. Physical Characteristics: The fiber diameter of these boards ranges from 3 to 4.5 microns, and they have a pH range of 2-12. They are also noted for their low fiber shrinkage, which is less than 3.5% at 1800°F over 3 hours​​.

 

Production Process

Ceramic fiber board are produced using several techniques:

  1. CVD Technique: Involves the deposition of a material’s vapor phase on a core substrate, often using tungsten and carbon C-type monofilaments​​.
  2. Melt Spinning Technique: Here, precursor materials are melted and spun through nozzles at high pressure, followed by cooling to solidify​​.
  3. Slurry Spinning: This process uses spinning of ceramic slurries, consisting of alumina particulates, alumina precursor suspension, and organic polymer​​.
  4. Chemical Conversion: Involves converting ceramic fibers into different compositions through chemical reactions​​.

 

Applications

Ceramic fiber boards have a wide range of applications due to their thermal resistance and insulating properties:

  1. Thermal Insulation Material: Used for high-temperature insulation seals, gaskets, thermal shields, and fire barriers​​​​.
  2. Reinforcement of Metals or Ceramics: Enhances the strength and durability of these materials​​.
  3. Protective Equipment: Used in protective blankets, fire retardant fabric, and expansion joint fabric​​​​.
  4. Architectural and Industrial Uses: Includes applications in fire doors, furnace insulation, high-temperature pipes, and roofing​​.

 

Advantages

Ceramic fiber boards offer several benefits:

  • Low elongation and retraction rates.
  • Excellent dielectric strength and chemical resistance.
  • Superior resistance to thermal shock.
  • Low thermal conductivity and porosity​​.

 

These features make ceramic fiber boards indispensable in industries where heat management is crucial. They are not only efficient in thermal insulation but also versatile, durable, and adaptable to various industrial and architectural needs​​.
