▎ 摘  要

NOVELTY - Preparation of silicon nitride fiber aerogel, involves containing silicon source, printing ink of carbon source and high molecular bonding agent, sintering at high temperature under the atmosphere of nitrogen, or printing the ink of the silicon source and the high molecular binding agent through 3D printing to obtain a printing piece, and subjecting the printing piece under the nitrogen atmosphere to sinter at a high temperature to obtain the silica-based silica aerogels. USE - Preparation method of silicon nitride fiber aerogel used in heat preservation and heat insulation, pollutant adsorption and sensor fields (claimed). ADVANTAGE - The method enables to prepare silicon nitride fiber aerogel, which is simple and cheap, and has excellent flame retardance, heat preservation, heat insulation and adsorption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a silicon nitride fibre aerogel.
