“…By applying the liquid charge chemical synthesis method, there are produced some boron carbidebased nanocomposites containing ferromagnetic components such as iron Fe and nickel Ni, namely, metal-ceramic nanocomposites containing boron carbide matrix and ternary metallic alloy binder in form of eutectic binary alloy Co-Ti, where Co partially is substituted by nickel Ni: B 4 C/(Co-Ni-Ti) [39][40][41][42][43]. There are also synthesized nano powders of complex compositions, which in addition to boron carbide and cobalt contain metal diborides MeB 2 (Me = Ti or Zr, rarely Hf) and, maybe, tungsten carbide WC at high temperatures (>1600°C) tending to be converted into tungsten boride W 2…”
