THERMALLY INSULATING SIC-BN AEROGEL FELT AND PREPARATION METHOD AND USE THEREOF
Disclosed are a thermally insulating SiC—BN aerogel felt, a preparation method and use thereof. The preparation method includes: heating and mixing a nitrogen source, a boron source, a solvent, and a silica aerogel powder to obtain a hot mixture, wherein the solvent is capable of dissolving the nitrogen source and the boron source; impregnating a graphite felt in the hot mixture, and cooling to obtain a gel felt; removing the solvent from the gel felt to obtain an aerogel felt; and in a protective atmosphere or in vacuum, heating the aerogel felt for a pyrolytic reaction to obtain the thermally insulating SiC—BN aerogel felt.
