Abstract EN
The excellent physical and chemical properties of boron carbide make it suitable for many applications.
However, its synthesis requires a large amount of energy and is time-consuming.
Microwave carbothermal reduction is a fast technique for producing well crystallized equiaxial boron carbide nanoparticles of about 50 nm and very few amounts of elongated nanoparticles were also synthesized.
They presented an average length of 82 nm and a high aspect ratio (5.5).
The total reaction time was only 20 minutes, which disfavor the growing process, leading to the synthesis of nanoparticles.
Microwave-assisted synthesis leaded to producing boron-rich boron carbide.
Increasing the forward power increases the boron content and enhances the efficiency of the reaction, resulting in better crystallized boron carbide.
