| titleOfInvention | Preparation method for titanium carbide nanoparticles |
| abstract | The invention belongs to the field of inorganic materials and material synthesis process, and relates to a preparation method for titanium carbide nanoparticles. Titanium carbide nanoparticles are prepared by adopting a sol-gel method and a carbon thermal reduction processThe method comprises the following steps of: preparing carbon sol by using resorcinol, methanal and anhydrous sodium carbonate as raw materials; preparing titanium sol by using tetrabutyl titanate or tetraethyl titanate as reactants and using nitric acid and deionized water as raw materials; mixing the carbon sol with the titanium sol, and performing a sol-gel reaction to obtain wet gel; aging the wet gel, and drying the wet gel under normal pressure to obtain titanium carbide precursors; performing a carbon thermal reduction reaction on the titanium carbide precursors in inert gas; and calcining in air, soaking in hydrochloric acid, washing, filtering and drying to obtain the titanium carbide nanoparticles. The preparation method has the advantages of readily available raw materials, simple equipment, and easy large-scale production; the prepared titanium carbide nanoparticles have small particle sizes and larger specific surface areas, can be used in the fields of high-temperature insulation materials, ceramic composite materials, cutting materials, abrasion-proof materials, photocatalytic materials, aerospace materials and the like. |
