{{Main|Boron nitride aerogel}}
Boron nitride aerogel is an [[aerogel]] made of highly porous BN. It typically consists of a mixture of deformed BN nanotubes and [[Boron nitride nanosheet|nanosheets]]. It can have a density as low as 0.6&nbsp;mg/cm<sup>3</sup> and a specific surface area as high as 1050&nbsp;m<sup>2</sup>/g, and therefore has potential applications as an [[Absorption (chemistry)|absorbent]], catalyst support and gas storage medium. BN aerogels are highly [[hydrophobic]] and can absorb up to 160 times their weight in oil. They are resistant to oxidation in air at temperatures up to 1200&nbsp;°C, and hence can be reused after the absorbed oil is burned out by flame. BN aerogels can be prepared by template-assisted [[chemical vapor deposition]] using [[borazine]] as the feed gas.<ref name=nat/>
