| Abstract | 本发明涉及碳化钨技术领域，具体提供一种纳米碳化钨及其制备方法。所述制备方法包括以下步骤：将钨源、碳源、溶剂进行混料处理，获得第一混合溶液；向所述第一混合溶液中加入乙醇，并调节所述第一混合溶液的pH值至8.5～9.0，获得第二混合溶液；对所述第二混合溶液进行静置老化处理，随后对经老化处理的所述第二混合溶液进行恒温加热处理，获得前躯体；在惰性气氛下对所述前躯体进行煅烧处理，获得纳米碳化钨颗粒。本发明方法可获得纯度高、粒径均一、球形的纳米级碳化钨颗粒，整个生产过程安全可靠，工艺条件简单易控、生产成本低，适于工业化大规模生产，而且获得的纳米碳化钨颗粒具有良好的催化特性。 |
| Other Abstract | The invention belongs to the technical field of tungsten carbide, and more specifically relates to a nanometer tungsten carbide, and a preparation method thereof. The preparation method comprises following steps: a tungsten source, a carbon source, and a solvent are subjected to material mixing processing so as to obtain a first mixed solution; ethanol is added into the first mixed solution, and the pH value of the first mixed solution is adjusted to 8.5 to 9.0 so as to obtain a second mixed solution; the second mixed solution is allowed to stand for aging treatment, after aging treatment, thesecond mixed solution is subjected to constant temperature heating treatment so as to obtain a precursor; the precursor is subjected to calcining at an inert atmosphere so as to obtain the nanometertungsten carbide particles. The preparation method is capable of obtaining the spherical nanometer tungsten carbide particles which are high in purity and uniform in particle size distribution; the whole production process is safe and reliable; the technology conditions are simple and are easy to control; production cost is low; the preparation method is suitable for industrialized large scale production; and the obtained nanometer tungsten carbide particles possesses excellent catalytic performance. |
