About Ceramic Fiber Blankets

Ceramic fiber blankets are specialized insulation materials designed to perform under extreme heat conditions. Manufactured from high-strength spun ceramic fibers, these blankets offer a balance of performance features unattainable by traditional insulation materials. They possess a remarkable ability to withstand thermal shock, a critical attribute for applications experiencing rapid temperature fluctuations.

Additionally, their innate high tensile strength ensures they maintain integrity and dimensional stability after repeated heating cycles, resisting shrinkage effectively. Notably, these blankets also exhibit low thermal conductivity, enhancing their ability to insulate while minimizing heat storage for efficient energy use. Lastly, their capability to absorb sound contributes an additional layer of utility, providing a quieter operational environment in industrial settings.

How Ceramic Fiber Blankets are Made

The production of ceramic fiber blankets involves a series of intricate steps, ensuring the final product meets the high standards required for industrial applications. Here’s a breakdown of the process:

Raw Material Selection

High-quality alumina-silica materials are chosen for their purity and ability to withstand high temperatures.


The raw materials are melted in a high-temperature furnace until they form a homogenous liquid.

Fiber Spinning

The molten material is then spun into fibers using either a blowing or spinning process, creating fine, flexible fibers characteristic of ceramic fiber blankets.

Collecting and Layering

These fibers are collected and layered to form a blanket of the desired thickness and density.


The layered fibers are then needled, entangling them to add strength and integrity to the blanket structure without the use of binders.

Cutting and Packing

Finally, the blankets are cut to specific dimensions and packaged for shipping. Optional treatments, such as adding aluminum foil backing, may be applied based on specific application requirements.

Types of Ceramic Fiber Blankets

Axim Mica offers a variety of ceramic fiber blankets designed to meet diverse application needs across different industries. The distinctions among these types largely focus on temperature ratings, density, and optional treatments, allowing for customized insulation solutions:

  • High-Purity Grade: Designed for higher temperature applications up to 1360°C, offering enhanced thermal stability.

  • Zirconia Grade: The highest temperature rating up to 1430°C, perfect for the most demanding environments that require superior thermal resistance.

Based on Density

  • #6 Density (96 kg/m³): Offers a balance between insulation performance and flexibility, suitable for a wide range of applications.

  • #8 Density (128 kg/m³): Provides increased durability and enhanced thermal resistance, ideal for industrial applications requiring robust insulation.

Optional Treatments

  • With Aluminum Backing: For applications needing reflective insulation or additional mechanical strength.

  • Without Aluminum Backing: Offers more flexibility and is suitable for wrapping or fitting into irregular shapes.

Frequently Asked Questions

Ceramic fiber blankets are utilized for high-temperature insulation in industries like aerospace, metalworking, and ceramics, providing thermal efficiency and protection.

While the initial cost might be higher than some traditional insulation materials, ceramic fiber blankets offer superior performance and durability, making them cost-effective for long-term applications.

Ceramic fiber blankets can absorb moisture. If wet, their insulation properties might temporarily decrease until fully dried out, without long-term damage to the material.

Direct washing is not recommended as it can alter the physical structure. If cleaning is necessary, gently remove surface contaminants without saturating the blanket.
