FIELD: chemistry.
SUBSTANCE: invention relates to materials with neutron-absorbing properties for protection against neutron radiation. Claimed is a fire-resistant neutron-protective material, consisting of a magnesium phosphate binding agent (24-33 wt %) and a powder part (76-67 wt %, with the powder part containing titanium hydride TiH2 (90.3-95.5 wt %), magnesium oxide MgO (2.7-4.5 wt %) and boron carbide B4C (1.8-5.2 wt %). Components are mixed to a homogeneous state and poured into a special cavity, and after hardening are subjected to thermal processing.
EFFECT: obtained material possesses long-term mechanical strength, heat resistance to ≈300°C, high heat conductivity, a temperature coefficient of linear expansion, close to the coefficient of construction steels, and high specific density of hydrogen and boron, contained in it, which ensures high coefficients of neutron radiation attenuation.
