Preparation of highly dispersed ultra-fine ZrC by ...
Ultra-fine zirconium carbide powder with particle size below 200 nm was produced by the carbothermal reduction of ZrO 2, graphite powder, and subsequent mechanical milling.After heat-treatment at 1400 °C for 2 h under vacuum, ZrC agglomerates (average size, 7.53 μm) were obtained with crystallite sizes of ~ 200 nm.Mechanical bead mill proved to be efficient in …
