Outline of Final Research Achievements

A condensed boric acid (H3BO3)-poly(vinyl alcohol) (PVA) product fiber was prepared by electrospinning. A boron carbide (B4C) precursor prepared from the condensed H3BO3-PVA product fiber by thermal decomposition in air had fibrous form and the microstructure consisted of highly dispersed boron oxide (B2O3) and carbon components. The morphology of B4C synthesized from the fibrous precursor exhibited characteristic connected fine particles.
