Aerogel Cost Constraint Market Application
Aerogel cost constraint market application
With the development of time, the requirement of building thermal insulation materials is higher and higher, with low proportion, fire prevention and low thermal conductivity. Compared with the existing thermal insulation materials, aerogel felt has lower thermal conductivity and excellent thermal insulation performance. Aerogel felt is lighter and the same quality can cover more areas. In addition, aerogel composite products are also excellent in sound insulation, fire prevention and moisture resistance.
Many industry insiders say that the biggest obstacle to the development of aerogel market is price. In the field of building insulation, thermal insulation, the existing insulation materials tens of yuan a square meter. Although aerogels were more than 200 yuan per square metre two or three years ago, with aerogel scale production, it has now dropped to over 100 yuan. But at present, the price of aerogels is still different from that of the market, and I believe that the future will be closer and closer.
Aerogels are mainly composed of silica aerogels, alumina aerogels, zirconia aerogels and carbon aerogels because of their different compositions. At present, silica aerogel technology is the most mature and widely used in the market. The industrialization development of aerogel insulation material at home and abroad mostly revolves around the application of silica aerogels in adiabatic applications.
The preparation process of carbon aerogels is also more mature. The carbon aerogel materials used as anode materials for lithium batteries and desalination electrodes have been applied in China. Moreover, carbon aerogels have been used as optical films for high laser damage thresholds in large laser devices. However, the production cost of carbon aerogel is high, hindering its application and expanding its application. Experts suggest that carbon aerogels should be simplified and their production cost should be reduced.
Once the production cost of aerogel can be significantly reduced, the market price will also drop, and the market will expand rapidly. For example, silica aerogels will revolutionize the replacement of traditional thermal insulation materials.
