内容記述 | The carbothermal reduction of boron oxide (B2O3) is the most common industrial manufacturing method for boron carbide (B4C) powder. As a low-temperature synthesis method for B4C powder, there is an approach using a condensed product prepared from boric acid (H3BO3) and an organic compound with a number of hydroxyl (-OH) groups (a polyol) such as glycerin, mannitol, and poly(vinyl alcohol) (PVA). A borate ester (B-O-C) bond was formed by the dehydration condensation of H3BO3 and a polyol, leading to the homogeneous dispersion of the boron and carbon sources at the molecular level. We performed the thermal decomposition of a condensed H3BO3-polyol product in air to control the amount of carbon to the stoichiometric C/B2O3 ratio required for the carbothermal reduction. Within the thermal decomposed product consisting of B2O3 and carbon components (B4C precursor), the B2O3-carbon microstructure at the nanometer scale was formed. The improvement of the dispersibility and homogeneity of the B2O3-carbon microstructure was conducive to the acceleration of the B4C formation at low temperature. | |||||
