Study on Preparation of Ultrafine Lead Tungstate for Radiation Protection and T-ray Shielding of the Gloves
摘要
Abstract
Lead tungstate combines the radiation shielding properties of tungsten and lead, and it is quite distinctive to manufacture lead tungstate with ultra-fine granularity to enhance its capacity of radiation shielding. The grain size of lead tungstate has direct impact on the ability of its protection from radioactive materials, the smaller the grain size and more uniform dispersion of lead tungstate, the better protective ability it is going to be. In this paper, soft-template synthesis was introduced to prepare ultra-fine PbWO4. Rigorous experiment conditions are settled to ensure the access to obtain ultra-fine, homogeneous lead tungstate product, and it is better than other physical and chemical preparation methods. The surface-active agent for the soft template, with S-60 for the water system W/O microemulsion zone, was used to synthesize successfully ultra-fine PbWO4. It was shown that dispersing agent S-60 in the soft template method produced ultra-fine PbWO4 with uniform granularity distribution. By using orthogonal experimental method, the best experimental conditions were obtained as follows： S-60 as surfactant dispersant with diluted 30 times concentration, solutions with pH9, 0.01 mol/L concentration of reactant, 1 300 rpm of stirring speed and slowly adding drops of Na2WO4 solution into Pb（Ac）2 solution. Based on the optimal experimental conditions, the product of ultra-fine product for .the anti-radiation protection filler has been made. The fine packing for the preparation of tungsten the gamma rays on the gloves is an average capacity of 5% or so.关键词
