Abstract
B4C ceramic pellets with diameter smaller than 0.7 mm have been simply fabricated via polyvinyl alcohol (PVA) assisted planet-type rotation method. Only commercial B4C powders and tiny amounts of PVA are needed in the experiment. The PVA solution is used to modify the commercial B4C powders. And the powders with adhesive properties are spheroidized to form green pellets during the rotation process. Results show that the green B4C pellets exhibit uniform size distribution and high sphericity. The appropriate diameter of 0.61 mm and high sphericity of 97.15% can be obtained by controlling the rotation time and the concentration of PVA solution. This fabrication method provides a low-cost and simple way to prepare B4C ceramic pellets with various diameters and high sphericity, and also sheds light on the mass production of other ceramic microspheres.
