The process to make boron nitride aerogels requires several key steps. The first step is to obtain the carbon aerogel template via a freeze drying process . Graphene oxide powder is one of the substances required to make this carbon aerogel, and is obtained in this paper by a synthesis process. After the freeze drying process to obtain the carbon aerogel, the aerogel needs to first go through pyrolysis before finally becoming a boron nitride aerogel by chemical vapor deposition.
