Abstract

Monolithic SiO2 aerogel, as a transparent insulation material, has extensive potential in the field of concentrated solar power. However, challenges still persist when it comes to the high-temperature solar thermal utilization of transparent SiO2 aerogel. In this study, a supercritical CO2 extraction drying process was employed to fabricate monolithic and highly transparent SiO2 aerogels. The impacts of high temperature (500–900 °C) on the light transmission, thermal insulation, thermal stability, and microstructural features of the aerogels were thoroughly investigated. The results indicate that the aerogel can achieve 93.8 % solar spectral weighted transmittance with small-scale mesopores (5–10 nm) after 5-h thermal treatment at 500 °C. High temperature can enhance the transmission of solar radiation through the aerogel, but it simultaneously decreases its thermal insulation performance. The effective thermal conductivity is 0.08 W/(m·K) at 100 °C and increases as the temperature rises. The aerogel is not suitable for high-temperature conditions above 900 °C as its nanoporous characteristics will be significantly diminished. Experimental tests under concentrated solar radiation reveal that the aerogel can achieve a stagnation temperature of 640 K at a concentration ratio of 5, which is 24.3 % higher than that of quartz glass, demonstrating its superior transparent thermal insulation performance.
