Spark Plasma Sintering of the Stock Material Made of the Boron Carbide Obtained by Different Methods

Аннотация

Abstract—The optimum modes of spark plasma sintering (SPS)—temperature, time, and pressure amplification—were determined; the structure and properties of blanks of boron carbide sintered by the above method from the powders obtained by the mechanochemical synthesis from carbon char and amorphous boron, by self-propagating high-temperature synthesis (SHS), and by the carbon reduction technique were studied. The optimum modes of the spark plasma sintering of the powder mix of carbon char and amorphous boron were determined.
