A Review on Advancements of Novel Building Thermal Insulation Materials: Zirconia Aerogels
Zirconia (ZrO2) aerogels have three-dimensional, cross-linked network structures where the main component is ZrO2. They have characters of acid–base duality, redox properties, high specific surface areas, high porosities, and high levels of thermal and chemical stability. Due to the above-mentioned characters, ZrO2 aerogels can be widely used in the field of construction as fireproof and thermal insulation, and has great potential in the field of building energy conservation. This paper aims to provide a timely review on recent advancements in the preparation, modification, and applications of ZrO2 aerogels. The research and applications of the direct sol–gel and organic acid-assisted sol–gel methods remain under-developed, however, these two methods have the greatest potential in future preparations of aerogels because of their low toxicity and low safety risk. Atmospheric drying is the most active field of research because of its low cost and compatibility with conventional atmospheric pressures. The widely used modification methods include (1) doping modification and (2) adding a binary composite, and the latter is comparatively more common because ZrO2 aerogels prepared via this method exhibit improved stability at high temperatures compared with corresponding aerogels prepared by doping.
