“…[1,2] The use of nanometric powders as reinforcement in ceramic matrix is one special application due to the good properties that these materials can provided to ceramics, such as mechanical reinforcement and enhancement on fracture toughness. [3,4,5,6] There are many paths to produce for production of materials at nanoscale, be used complex assembly process or traditional routes [7] . High energy milling is one traditional route widely applied on nanoceramics production.…”

Production of nanometric ceramic powders is one of the most recent advances in materials science. However the large scale production of some materials is still a challenge. There are two approaches to the fabrication of nanomaterials that results in powders with distinct characteristics. In high energy milling the particle size is reduced by mechanical forces to achieve nanosized particles. Another technique is reactive milling in which nanometric particles are synthesized by mechanically activated reactions. In this work NbC nanoparticles were produced by high energy milling of commercial NbC and by self-sustained high energy reactive milling of Nb2O5-Al-C powder mixture. The NbC particles were desagglomerated for 1h in a planetary mill. The obtained powders were characterized by X-ray diffraction, scanning electron microscopy and laser diffraction. The objective of this study was to compare the efficiency of two employed techniques to determine the most of producing nanoscale NbC.

“…Co-precipitated products were divided into different batches: one was directly crystallised thermally, and the others were submitted to different milling procedures in order to optimize powder properties and preparation procedure. [12][13][14] The characteristics of the different products were evaluated by measurement of particle size distribution (PSD), thermogravimetric analysis (TGA), X-ray diffraction (XRD), specific surface area (BET) and scanning electron microscopy (SEM).…”
