High-energy ball milling of powder B–C mixtures

Laser-induced reactions in layers of B4C + Fe and B + C + Fe mixtures on a steel substrate

“…1), milling caused the reflections from boron to disappear and slightly broadened the reflections from graphite (crystallite size, ~20 nm) and iron (crystallite size, 50 nm). As reported earlier [8], high energy milling of boron-carbon mixtures for several hours does not lead to boron carbide formation, in agreement with our data.…”

Effect of APC addition on precursors properties during synthesis of B4C nano powder by a sol–gel process

“…These unique characteristics make boron carbide more interesting than other ceramic carbides. Among these properties are high neutron adsorption, low density, high hardness (close to that of diamond), and high chemical and wear resistance [1][2][3][4]. This ceramic material is mostly used in military industry as body armors, in electronics as thermocouples, in nuclear power plants as an absorber for neutron radiation, and also for wear applications for example as nozzles for abrasive slurries [5][6][7].…”

Synthesis of Boron Carbide by Reactive‐Pulsed Electric Current Sintering in the Presence of Tungsten Boride

“…Being sources and sinks of vacancies, the structural defects increase the diffusion mobility of particles and their sinterability . The methods of mechanochemistry have been often used to obtain submicrometric‐sized B 4 C or B 4 C‐based composite materials with nanosized crystallite dimensions . The enhanced diffusivity and sinterability of nanoparticles is based on well‐developed grain boundary network and to only a few atomic jumps separating grain interiors from the boundaries.…”
