| titleOfInvention | Preparation method of hafnium carbide nano-powder |
| abstract | The invention relates to a preparation method of hafnium carbide nano-powder. The preparation method comprises steps as follows: 1) preparing hafnium-containing gel: dissolving HfCl4 and C6H8O7*H2O in deionized water, continuously stirring the mixture to fully dissolve the HfCl4 and the C6H8O7*H2O, then adjusting the pH value to range from 2 to 3 with an ammonia water solution, and performing magnetic stirring treatment at the constant temperature of 60-80 DEG C to obtain the hafnium-containing gel; 2) preparing precursor powder: placing the hafnium-containing gel into a low-temperature tube furnace for heat treatment to obtain the precursor powder; (3) preparing the hafnium carbide nano-powder: placing the precursor powder into a planetary ball-milling tank for high-energy ball milling, and placing obtained powder into a discharge plasma sintering furnace for reactions to obtain the hafnium carbide nano-powder. The method is simple in technology, low in energy consumption, good in repeatability and good in industrial prospect, and the prepared hafnium carbide nano-powder is a high-activity nano-scale product with hafnium carbide distributed evenly and is even in crystal grain distribution, high in purity and good in degree of crystallinity. |
