B4C nanopowder Bor carbide pulveris pro materia glutino
depictio producti
Boron carbide substantia inorganica est, plerumque cinereo-nigra.Habet altam densitatem (2.55g/cm³), altum punctum liquescens (2350° C), et excellentem stabilitatem chemicam et effusio neutronis.Materia valde dura, duritiei adamantis aequalis, proprietates neutronis absorber habet.Hoc usum carbidi boronis in multis agris perduxit, ut energiae nuclearis sicut neutron absorber, tum obsistens materias gerunt, incrementa ceramica, tempus leve, armatura levis, et praesertim nuclei reactor neutron absorber.
