| titleOfInvention | Method for preparing massive titanium carbide, titanium nitride or titanium carbonitride aerogel |
| abstract | The invention relates to a preparation method of blocky titanium carbide, titanium nitride or titanium carbonitride aerogel. Using resorcinol-formaldehyde (RF) and tetrabutyl titanate as a carbon source and a titanium source respectively, using alcohol as a solvent and using deionized water as a hydrolytic agent, preparing wet gel by one-step sol-gel process by adding acid catalysts respectively, and obtaining RF/TiO by solvent replacement and supercritical drying of the wet gel 2 The composite aerogel precursor is prepared by controlling high-temperature carbothermic reduction and calcination decarbonization in inert atmosphereBulk titanium carbide, titanium nitride or titanium carbonitride aerogel materials. The method is simple and convenient to operate, the size of reaction particles is smaller, the contact area between the particles is large, the reaction is more thorough due to the adoption of the sol-gel process, the carbon generated by pyrolysis of the organic aerogel (RF aerogel) is used for carrying out the carbothermic reduction reaction, and no carbon reducing agent is required to be additionally added, so that the process is greatly simplified, the production cost is reduced, and the operability and controllability of the process are improved. |
