Claim 0:
1. A method for a production of boron carbide nano-sized particles and/or submicron-sized particles, comprising the following sequential steps:
a) preparing a fluid mixture comprising elemental boron, glycerin and one or more carboxylic acids, wherein a molar ratio of the glycerin to the one or more carboxylic acids is within a range between 10:1 and 10:7.5,
b) keeping the fluid mixture at a temperature within a range between 100° C. and 290° C. to obtain a first mid-product,
c) performing a solidification on the first mid-product by heating the first-mid product to a temperature within a range between 350° C. and 750° C. to obtain a second mid-product in a solid form,
d) sintering the second mid-product at a temperature of 1250° C. or higher to obtain the boron carbide nano-sized particles and/or submicron-sized particles.
