Abstract

Abstract Boron carbide nanopowders and nanowhiskers were synthesized using phenolic resin and boron alkoxide as precursors through sol–gel process in water–solvent–catalyst–dispersant system. The effects of soaking time on free carbon content and synthesized B 4 C particles morphology were evaluated at 1270 °C. The synthesis process of B 4 C nanopowders was completed at 1270 °C after 1 h while B 4 C nanowhiskers were heterogeneously nucleated and grown from obtained nanopowders after 3 h.
