  • CEMENTITIOUS SHIELDING COMPOSITION FOR THE WIDE-SPECTRUM CAPTURE OF THERMAL, EPITHERMAL, AND FAST NEUTRONS
    Publication number: 20240105352
    Abstract: The present disclosure provides for cementitious shielding compositions, methods of making the cementitious shielding composition, structures incorporating the concrete cementitious shielding composition, and the like, where the cementitious shielding composition includes elemental boron and/or a boron compound, for example as boron particles. The boron particles can be homogeneously distributed throughout the cementitious shielding composition and can have a largest least dimension of about 100 microns or less. The present disclosure, in some aspects, can reduce or eliminate problems associated with minerals found in concrete aggregates, because those materials are degraded over time by neutron radiation, which leads to disorganized lattice structures, manifested as damage by radiation-induced volumetric expansion (RIVE), and potentially further damage from alkali-silica reaction (ASR).

  • Boric acid-containing lubricants for powered metals, and powered metal compositions containing said lubricants
    Patent number: 6001150
    Abstract: Boric acid-containing lubricants are disclosed which consist essentially of boric acid and at least one other powder metallurgy lubricant and provide a synergistic free-flowing composition. There are also provided novel compositions of matter for forming sintered metal components comprising a mixture of sinterable, powdered metal and the said lubricants.
