Hierarchically structured aluminum borate whisker aerogel via sol-gel method and in-situ reaction

Caption

Hierarchical aluminum borate whisker aerogels were prepared via a sol-gel process, followed by freeze-drying and high‑temperature in situ reaction. The whiskers in matrix and those on mullite fibers show remarkably different growth patterns and growth mechanisms. The aerogel shows high thermal resistance, low thermal conductivity and high compressive strength.
