The component percentage of the anti-radiation, shielding material is Pb 2-10%, Ba 1-5%, TiO2 5-15%, TiB2 1-10%, the rest is aluminum (Al) Under the smelting temperature, the Al is melt down. Then add the anti-radiation material of Pb, Ba, TiO2 and TiB2, the distribution of the material can be controlled by utilizing the magnetic field and controlling the cooling speed. Thus the grading structure is formed. The material is applied to protect the electrnic component of the spacecraft from outer-sphere radiation damage.
