Ceramic Fiber

Overview of Ceramic Fiber

Ceramic Fiber is a lightweight, high-temperature insulation material composed of alumina-silica-based amorphous fibers. Engineered for extreme thermal management, it offers very low thermal mass and excellent insulating properties, making it the ideal solution for energy-efficient furnaces, kilns, and high-temperature industrial processes up to 1600°C.

Features of Ceramic Fiber

• Exceptional Thermal Insulation: Extremely low thermal conductivity, ensuring maximum energy efficiency and heat containment.
• Low Heat Storage: Minimal thermal mass allows for rapid heat-up and cool-down cycles, improving process speed and efficiency.
• High-Temperature Stability: Maintains structural integrity and insulating value in continuous use at temperatures up to 1600°C, depending on the grade.
• Lightweight & Flexible: Easy to handle and install, available in blankets, boards, modules, and papers to conform to complex geometries.
• Excellent Thermal Shock Resistance: Withstands rapid temperature changes without spalling or cracking.

Applications of Ceramic Fiber

• Thermal Processing: Lining for industrial furnaces, kilns, ovens, and boilers across metal, glass, and ceramic industries.
• Expansion Joints & Sealing: High-temperature gaskets, seals, and expansion joints in power generation and petrochemical systems.
• Fire Protection: Insulation in firewalls, fire doors, and passive fire protection systems.
• Aerospace & Automotive: Heat shields, exhaust insulation, and thermal barriers.
• Back-up Insulation: Secondary insulating layer behind dense refractory linings.

5 FAQs of Ceramic Fiber

1. What is the difference between ceramic fiber blanket, board, and module?
Blankets are flexible rolls for lining curved surfaces. Boards are rigid for flat surfaces and structural strength. Modules are folded blankets pre-assembled into blocks for faster furnace construction.

2. Is ceramic fiber safe to handle?
Newly installed ceramic fiber is generally safe. However, when cutting or disturbing aged fiber, dust containing crystalline silica can be released. Always use appropriate personal protective equipment (PPE) like respirators.

3. What is its maximum continuous operating temperature?
This varies by grade, but typically ranges from 1100°C for standard grades to over 1400°C for high-purity, polycrystalline grades. Always consult the specific product data sheet.

4. Can ceramic fiber get wet?
While it can get wet, moisture will temporarily reduce its insulating properties until it fully dries out. Prolonged exposure to steam or water can lead to degradation and loss of strength over time.

5. How is ceramic fiber installed?
Installation methods vary by form. Blankets are often layered and secured with studs/washers. Modules are mechanically anchored. Boards are cemented or anchored in place.
