Boron carbide powder is a starting material for sintering and hot pressing in the manufacture of boron carbide sintered parts. In this form it can be found, among other things, in dressing and grinding stones and as a lining for ball mills and mortars. Boron carbide powder is also used as a sintering additive for high-performance SiC ceramics.

Tool life comparison of ball-end mill cutters made of sintered carbide and of boron nitride (X153CrMoV12 − 60 ± 1 HRC, D = 16 mm, f z = 0.1 mm/edge, a p = 0.1 mm). In connection with the above, an important practical conclusion can be drawn.
ball grinding of boron. The process involves extensive ball milling of boron powder for a long period of time up to 150 h in NH 3 gas followed by annealing at high temperature up to 1300°C in N 2 environment It was suggested that a nitriding reaction was induced between boron powder and NH 3 gas due to high energy milling resulting in metastable disordered BN nanostructures and boron ...
It is well known that boron carbide has a broad non-stoichiometry range (9–20 at.% C). The boron carbide synthesized in this work is close to the congruently melting composition . Mechanical milling was conducted in a SPEX 8000 mill (SPEX CertiPrep, Metuchen, NJ) with a tungsten carbide ball and a tungsten carbide vial.
Abstract. Boron carbide nanoparticles were produced using commercially available boron carbide powder (0·8 μm). Mechanical milling was used to synthesize Al nanostructured powder in a planetary ball-mill under argon atmosphere up to 20 h. The same process was applied for Al–4 wt% B4C nanocomposite powders to explore the
