Sintering of Boron and Boron Carbide

Characterization of B4C and LaB6 by Ultrasonics and X-Rays Diffraction

“…Boron carbide was produced by direct synthesis from the elements at temperature 2000 • C. The pellets were hot pressed at temperatures 1900-2100 • C and pressures 20-40 MPa in boron nitride lined graphite moulds using resistance and inductive heating. 4 Shock compression, as a result of an explosive detonation, was realized in specialdesign ampoules filled with pure stochiometric boron carbide powders. The explosive compacting of powders based on B 4 C was performed within the wide range of treatment parameters -pressure and temperature with the use of loading cylindrical geometry.…”

Hardness and wear resistance of B4C ceramics prepared with several additives

“…However, despite the technological interest in B 4 C based ceramics, the sintering of pure B 4 C components has proved quite difficult, mainly due to the strong covalent bonding, which is responsible for the intrinsically low diffusion mobility [9].…”

Fabrication and characterization of B4C-based ceramic composites with different mass fractions of hexagonal boron nitride

“…However, poor sinterability [11][12][13], machinability [14] and tribological performance [15,16] of B 4 C ceramic have restricted its engineering application. The tribological performance of B 4 C sliding against 45 steel has been performed by Gogosti et al [16].…”
