NOVELTY - Inorganic fiber one-dimensional multi-element nano-micron composite crystal radiation protective material includes zirconium material, graphene, crystalline silicon wafer and iron salt. The is prepared by dissolving 100 mg iron salt in a water-polyol mixed solution, dispersing uniformly with ultrasonic waves, and then introducing argon gas to prepare a solution of 0.1-3 mol/l. 10 mg crystalline silicon wafers are pulverized into powder, mixed to the prepared solution under stirring, and then added oxalic acid under stirring to obtain oxalic acid solution. The obtained solution is sealed and moved to an oven at 100-200?oC for 3-16 hours to obtain a precipitate. USE - Inorganic fiber one-dimensional multi-element nano-micron composite crystal radiation protective material used in nuclear energy and various nuclear reactors. ADVANTAGE - The inorganic fiber one-dimensional multi-element nano-micron composite crystal radiation protective material has low specific gravity, high performance, uses safety, and effectively absorbs high energy X ray and beta ray. DETAILED DESCRIPTION - Inorganic fiber one-dimensional multi-element nano-micron composite crystal radiation protective material includes zirconium material, graphene, crystalline silicon wafer and iron salt. The is prepared by dissolving 100 mg iron salt in a water-polyol mixed solution, dispersing uniformly with ultrasonic waves, and then introducing argon gas to prepare a solution of 0.1-3 mol/l. 10 mg crystalline silicon wafers are pulverized into powder, mixed to the prepared solution under stirring, and then added oxalic acid under stirring to obtain oxalic acid solution. The obtained solution is sealed and moved to an oven at 100-200?oC for 3-16 hours to obtain a precipitate. 30 mg graphene is added to 60 ml deionized water under dispersing ultrasonically for 2-3 hours to obtain an aqueous solution of graphene, and added 0.6-2g dichloroacetic acid to the aqueous solution of graphene at 30-70?oC for 4-6 hours under stirring and then cooled to room temperature to obtain a precipitate. The obtained precipitate is stirred and added to the mixed solution to obtain a mixed paste. Zirconium metal is used as the heating element of the crystal synthesis furnace. The obtained paste is applied on the surface of the zirconium metal at 180-1000?oC for 4-12 hours, and then cooled to room temperature.
