Plates which absorbs neutrons, based on boron carbide and of carbon, and for the manufacture

摘要

P materials absorbing neutrons, in particular in the form of thin plates and of large area, with a volume of 45 to 60 by boron carbide, and 25 a, 5 by the free carbon. / p & & p & they have a density of 1,4 has 1,8gcm, a resistance to flexion of 15 has 45nmm, a resistance to compression of 25 has 60nmm, a module for elasticity of 10000 has 20000nmm, and a resistance 10rads to ionizing radiation. / p & & p & these plates are particularly advantageous for use in the decantation basins for the fuel elements uses from top plug nuclear. / p
