Plasma milling results in more reactive sites and a larger contact area between WO3 nanoparticles and C atoms, and simultaneously generats more oxygen vacancies and defects on the surfaces of WO3 and C respectively via plasma discharge as describe in the article, number 2200175 by Zhongchen Lu and co‐workers. Thus, the reaction temperature for the carbothermal reduction reaction reduces significantly...
This work prepares nanocrystalline tungsten carbide (WC) powder using conventional ball milling or plasma milling (P‐milling) to process tungsten trioxide (WO3)–carbon (C) mixtures, with subsequent carbothermal reduction. The aim is to assess the effects of a discharge plasma on the microstructure of these materials. The results indicates that WC powders with particle sizes of less than 100 nm could...
