Problems solved by technology
The invention relates to a preparation method of an aluminum base gadolinium oxide neutron absorbing plate. The compact aluminum base gadolinium oxide neutron absorbing plate is prepared to meet a protection requirement of neutron radiation shielding for a spent fuel storage rack of a nuclear power station, and is prepared with aluminum powder, gadolinium oxide powder and copper powder as raw materials after powder metallurgy is performed and rolling is performed. The neutron absorbing plate is silver white. The neutron absorption rate is 95%. The gadolinium oxide distributes uniformly. Particles are closely connected with a matrix. The tensile strength is 170MPa and the elongation is 12%. The preparation method is advanced and reasonable in technology and accurate and full in parameter, and is an advanced method for preparing the aluminum base gadolinium oxide neutron absorbing plate.
