What is ceramic fiber made of?
Ceramic fiber is a new type of high-temperature refractory material widely used in various fields such as metallurgy, chemical engineering, and power. It has excellent characteristics such as high temperature resistance, thermal insulation and fire prevention, and therefore plays an important role in industrial kilns, thermal insulation equipment, and energy-saving building materials.
The main components of ceramic fibers
Ceramic fibers are mainly composed of pyrophyllite, high-purity alumina 40% (Al ₂ O3) with additives, and silica 50% (SiO ₂). Some special types of ceramic fibers may also be added with zirconia (ZrO ₂) or other metal oxides to improve their fire resistance and mechanical strength. These raw materials are melted at high temperatures and manufactured into fibrous materials through blowing or spinning processes, ultimately forming various products such as ceramic fiber cotton, ceramic fiber blanket, ceramic fiber board, ceramic fiber module, etc.
Characteristics of Ceramic Fibers
1. Excellent high temperature resistance: can withstand high temperatures from 1000 ℃ to 1600 ℃, and is not easily deformed or powdered after long-term use.
2. Good thermal insulation effect: Low thermal conductivity can effectively reduce heat loss and improve energy utilization efficiency.
3. Lightweight and low-density: Compared to traditional refractory bricks and castables, ceramic fiber products are lighter and easier to install and maintain.
4. Strong corrosion resistance: It has good corrosion resistance to most chemical substances and is suitable for complex industrial environments.
