The Ultimate Buyer’s Guide: How to Purchase Ceramic Fiber Board
Are you in the market for Ceramic Fiber Board? Look no further.
This all-inclusive buyer’s guide provides you with crucial insights into Ceramic Fiber Board, which find applications in metallurgical industry, power industry, ceramic industry, chemical industry and other heat treatment high temperature industries. Whether you’re contemplating importing them for your projects or planning local distribution, this guide furnishes invaluable information to guide your decision-making process.
Chapter 1
What is Ceramic Fiber Board?
Ceramic Fiber Board, also known as alumina-silica fiber board,is a high-performance refractory material engineered for extreme-temperature environments. Composed primarily of ceramic fibers derived from alumina (Al₂O₃), silica (SiO₂), and zirconia (ZrO₂), it is formed through a precise vacuum molding process where fibers are combined with inorganic binders like silicon sol or iron sol. This results in a rigid, lightweight board with exceptional mechanical strength, even after prolonged exposure to heat . Unlike flexible alternatives like ceramic fiber blankets or felts, ceramic fiberboard offers structural support and dimensional stability, making it ideal for applications requiring load-bearing capabilities or resistance to thermal shock and mechanical stress.
Chapter 2
Features of Ceramic Fiber Board
Ceramic Fiber Board stands out for its unique combination of high-temperature resilience, thermal efficiency, and versatile mechanical properties, positioning it as a preferred choice across industries. Here’s a detailed breakdown:
1. High-Temperature Resistance
Withstands continuous heat from 1000°C to 1400°C, and up to 1600°C for zirconia ceramic fiberboard. Maintains shape under extreme heat, outperforming standard refractory bricks.
2. Low Thermal Conductivity
Delivers superior insulation with values as low as 0.05 W/(m·K), helping reduce heat loss and save energy in kilns, industrial ovens, and furnaces.
3. Lightweight & Easy to Install
Much lighter than traditional refractories (200–1200 kg/m³). Easy to cut and shape for custom lining in boilers, combustion chambers, or pipeline insulation.
4. Strong & Durable
Withstands up to 20 MPa of mechanical stress. Resistant to corrosion from acids, alkalis, and molten metals like aluminum or copper. Ideal for chemical plants and foundries.
5. Additional Advantages
Low heat storage: Improves thermal efficiency during heating/cooling cycles.
Sound-absorbing: Reduces noise in industrial systems.
Asbestos-free: Safe, non-toxic, and eco-friendly.
