The ceramic fiber aerogel industry has high technical barriers and my country’s research has made new progress

Ceramic fiber aerogel refers to a high-performance material made of pre-oxidized wire as the base material and compounded into the pores of the aerogel material through a special process. Ceramic fiber aerogel has the advantages of good flame retardancy, high temperature resistance, lightweight and high strength, and is widely used in electronic and electrical, automobile manufacturing, construction engineering, aerospace and other fields.

The ceramic fiber aerogel industry has high technical barriers and its preparation methods have flaws. The main preparation methods of ceramic fiber aerogels include direct spinning, three-dimensional printing, vacuum filtration, layer-by-layer stacking, self-assembly, etc. The direct spinning method has problems such as poor quality of finished products and difficulty in controlling parameters, and has not yet been widely used; the layer-by-layer stacking method refers to first using a chemical vapor deposition method to make fiber sheets, and then stacking them to make finished products. This method can be used to prepare high elasticity Ceramic fiber aerogels are prone to problems such as interlayer peeling.

According to the “2023-2027 Ceramic Fiber Airgel Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center , in recent years, the aerogel market demand has become increasingly strong. The global aerogel market size will reach US$1.06 billion in 2022, a year-on-year increase of 11.6%. Ceramic fiber aerogel is an emerging product in the aerogel market. Currently, there are very few companies in the world with large-scale production capabilities and their market share is low. In the future, with the improvement of technological maturity, the output and quality of ceramic fiber aerogels will be further improved.

Ceramic fiber aerogels are widely used in electronic and electrical, automobile manufacturing, construction engineering, aerospace and other fields. In the field of electronics and electrical equipment, ceramic fiber aerogels can be used as thermal insulation materials for electronic equipment; in the field of automobile manufacturing, ceramic fiber aerogels can be used to produce new energy vehicle power batteries; in the field of construction engineering, ceramic fiber aerogels have It has sound absorption, heat insulation and other functions, and can be used to produce wall insulation boards and sound insulation boards. As downstream demand grows, the development prospects of the ceramic fiber aerogel industry will continue to improve.

At present, my country’s ceramic fiber aerogel industry is enthusiastic about research and development and has achieved certain results. In August 2022, Professor Ding Bin and Researcher Zhang Shichao from the team of Academician Yu Jianyong of Donghua University reported a flexible ceramic nanofiber aerogel (FCNA) based on bubble-assisted freeze casting technology. This product has full-frequency noise absorption performance , can be used as efficient sound-absorbing material. In the future, with in-depth research, the application scope of ceramic fiber aerogels will be further expanded.

Industry analysts said that ceramic fiber aerogels have excellent performance and have good application prospects in many fields. Due to factors such as high technical barriers and high production costs, ceramic fiber aerogels have a low market share and the industry is developing slowly. In the future, with the improvement of independent research and development capabilities of enterprises, the ceramic fiber aerogel industry will gradually develop in the direction of high performance, and its market size will expand by then.
