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 nanosheets. It can have a density as low as 0.6 mg/cm3 and a specific surface area as high as 1050 m2/g. Therefore, it has potential applications as an 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 °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. Adding boron nitride to silicon nitride ceramics improves the thermal shock resistance of the resulting material. BN is also added to silicon nitride-alumina and titanium nitride-alumina ceramics for the same purpose. Other materials reinforced with BN include alumina and zirconia, borosilicate glasses, glass ceramics, enamels, and composite ceramics with titanium boride-boron nitride, titanium boride-aluminum nitride-boron nitride, and silicon carbide-boron nitride composition.
