    • A method for increasing the boron.sup.10 content of a neutron absorbing article, such as one in flat, flexible sheet shape, includes coating a surface of such article with a solidifiable liquid synthetic organic polymeric material, such as a phenol formaldehyde type resin, applying boron carbide particles to the polymeric material and solidifying the polymer, such as by curing to cross-linked permanently set form, so as to hold the neutron absorbing boron carbide particles in place thereon. In highly preferred embodiments of the invention the boron carbide particles applied will extend beyond the surface of the external material and will serve as anchoring means for applications of subsequent coatings and the plurality of coatings, usually after initial partial curing to solidify them and make them form-retaining, will be permanently cross-linked simultaneously. In another aspect of the invention the plurality of flat neutron absorbing articles may be joined together by contacting surfaces thereof with such a coating material, preferably containing boron carbide particles, and curing it.
    • 用于提高中子吸收制品(例如平板,柔性片状)中的硼10含量的方法包括用可凝固的液体合成有机聚合物材料如酚醛树脂涂覆这种制品的表面,施加碳化硼 颗粒到聚合物材料并固化聚合物,例如通过固化成交联的永久固化形式,以便将中子吸收碳化硼颗粒保持在其上。 在本发明的非常优选的实施方案中,施加的碳化硼颗粒将延伸超出外部材料的表面,并且将用作后续涂层和多个涂层的应用的锚固装置,通常在初始部分固化之后,使它们形成 将会同时永久地交互。 在本发明的另一方面,多个平的中子吸收制品可以通过使其表面与这样的涂层材料接合,优选地包含碳化硼颗粒并固化。
