The thermal conductivity of ceramic fibers has the following characteristics:
1. Low thermal conductivity: Ceramic fibers have low thermal conductivity, with a thermal conductivity coefficient generally ranging from 0.03 to 0.06 W/m · K, which is much lower than the thermal conductivity of metal materials. This enables ceramic fibers to have good insulation performance in high-temperature environments.
2. High temperature stability: Ceramic fibers can maintain stable thermal conductivity in high-temperature environments without significantly increasing or decreasing thermal conductivity due to high temperatures. This enables ceramic fibers to effectively insulate themselves in high-temperature environments.
3. Corrosion resistance: Ceramic fibers have good corrosion resistance and will not be corroded by most chemicals. This enables ceramic fibers to maintain their thermal conductivity in various corrosive environments.
4. Insulation: Ceramic fibers have good insulation performance and can effectively isolate the conduction of heat. This makes ceramic fibers widely used in fields such as electronics and power.
                                                      It should be noted that different types of ceramic fibers have different thermal conductivity characteristics, and the specific thermal conductivity needs to be determined based on the specific material and structure.
