Abstract

A neutron-absorbing material is formed by a process which includes the steps of: mixing an absorptive material having a high thermal neutron capture cross-section (e.g., B.sub.4 C), a neutron-moderating material (e.g., graphite) and a binder (e.g., a phenol formaldehyde resin); shaping such mixture; curing such shaped mixture (e.g., to complete polymerization of the resin and to have only a carbon residue); and siliconizing such shaped and cured mixture. The resulting product has been formed to be denser and stronger, and more oxidation- and abrasion-resistant than prior art compositions.
