In-situ mechanical process for preparation of the polyvinyl alcohol (PVA) coated nano-B4C powder was investigated by using a high-energy ball mill. The produced PVA coat on the surface of nano-B4C particles was observed by x-ray diffraction (XRD) and confirmed by TEM images. The average particle size of the produced nano-B4C/PVA particles was in the range of several tens to hundreds of nanometers...
