Growth behavior of TiB 2 hexagonal plates prepared via a molten‐salt‐mediated carbothermal reduction

TiB 2 powders were successfully synthesized by a molten‐salt‐mediated carbothermal reduction method. The products obtained at 1300°C for 2 hours were hexagonal plates with side length of 3‐8 μm and thicknesses of 200‐500 nm. The microstructural evolution with temperature confirmed that the growth of...

Description
Summary:TiB 2 powders were successfully synthesized by a molten‐salt‐mediated carbothermal reduction method. The products obtained at 1300°C for 2 hours were hexagonal plates with side length of 3‐8 μm and thicknesses of 200‐500 nm. The microstructural evolution with temperature confirmed that the growth of TiB 2 hexagonal plates was a layer‐by‐layer growth controlled by a two‐dimensional nucleation. No‐uniform grains were observed attached on side and step edges of TiB 2 plates, which became finer and disappeared during the growth. This indicated that layer growth and growth on the side of TiB 2 plates followed the surface adsorption growth model.
