The preparation process of aluminum based boron carbide neutron absorption materials?
Its feature is that the preparation steps are as follows: (1) aluminum powder pretreatment; (2) B4C powder pretreatment; (3) Ball milling mixing: (4) Pressing element failure: (5) Hot pressing sintering. Using a dual pre-treatment process, two types of powders are pretreated before mixing. The process of drying twice and ball milling once improves the dryness of the powder, which is beneficial for subsequent processes and helps to improve the density of the neutron absorbing material in the final product. This further enhances the interface bonding between BC powder and aluminum powder, ensuring uniform mixing of the powder and stable composition, and ensuring stable performance of the product.
