Isochronal Oxidation Experiments on Boride and Carbide Powders

The isochronal oxidation of WC, iron-neodymium-boron (Fe₁₄Nd₂B) and TiB₂ powders have been investigated to establish an experimental basis for quantitative particle size and distribution determination. The chemical reactions involved have been established using a range of surface analytical techniques, including optical and scanning electron microscopy and X-ray diffraction.
