Another big breakthrough in Material science ..
Baotou Steel Group issued a document on May 3 stating that Baotou Steel Group has made a breakthrough in the research and development of rare earth fiber airgel materials, which have the characteristics of low density, low thermal conductivity, high elasticity and high temperature resistance.
Airgel materials are widely used in chemical insulation, new energy vehicles, clothing and other fields, and the demand and index requirements are gradually increasing. Baotou Rare Earth Research Institute and Lanzhou University jointly developed a flexible rare earth fiber aerogel. The material has low density, low thermal conductivity, high elasticity, high temperature resistance and other characteristics. After comparing the thermal conductivity at various temperature stages, it is in this field The indicators are at an advanced level .
the two parties will cooperate to tackle key issues based on the market demand for high-performance thermal insulation materials and the insufficient brittleness of traditional ceramic fibers. High-performance thermal insulation materials must have the characteristics of lightweight insulation, efficient thermal insulation, high-temperature stability, and good mechanical properties. Finally, the molecular induction and cation vacancy control strategies were determined, and a rare earth fiber aerogel material using low-cost, high-abundance rare earths such as lanthanum and cerium as raw materials was successfully developed.
IT Home’s inquiry found that the thermal conductivity of this material at room temperature is as low as 0.012W/(m·K) , and the maximum operating temperature reaches 1600 degrees Celsius and above . It is expected to be used in spacecraft, chemical industry and building materials thermal insulation, and new energy battery explosion-proof , cryogenic cold storage, catalysis, environmental pollutant control and other fields have been promoted and applied.
