Aerogels are unique porous solids having exceptional low relative density together with high specific surface area, making them very attractive materials for scientific research and industrial applications. Polymer derived ceramic aerogels are a new class of materials obtained through the pyrolysis of sol-gel/preceramic polymers. Herein this review, some of the representative formation methods and applications of polymer derived ceramic aerogels are highlighted with a specific focus on the thermal, electrical, and adsorbent related properties.
