Breakthroughs have been made in the research and development of rare earth fiber aerogel materials, which are characterized by low density, low heat conduction, high elasticity and high temperature resistance.
Aerogel materials are widely used in chemical insulation, new energy vehicles, clothing and other fields, and the demand and index requirements are gradually increasing. Recently, a flexible rare-earth fiber aerogel has been developed. The material has the characteristics of low density, low thermal conductivity, high elasticity, high temperature resistance, etc. Through the comparison of thermal conductivity at various temperature stages, the indicators in this field are at an advanced level.
In 2022, based on the market demand for high-performance thermal insulation materials and the lack of brittleness of traditional ceramic fibers, cooperation will be carried out to tackle key problems. Focusing on the characteristics of high-performance thermal insulation materials, such as lightweight insulation, efficient thermal insulation, high temperature stability, and good mechanical properties, molecular guidance and cation vacancy control strategies will be finally determined, and rare earth fiber aerogel materials with low cost and high abundance of rare earth such as lanthanum and cerium will be successfully developed.
The thermal conductivity of this material is as low as 0.012W/(m · K) at room temperature, with a maximum operating temperature of 1600 degrees Celsius or above. It is expected to be promoted and applied in fields such as spacecraft, chemical and building materials insulation, explosion-proof new energy batteries, cryogenic insulation, catalysis, and environmental pollution control in the future.
