  • Neutron- absorbing composite material and its production process
    Patent number: 5772922
    Abstract: The invention relates to a neutron-absorbing composite material and its production process.This material comprises a ceramic homogeneous matrix, e.g. of boron carbide B.sub.4 C or BN, in which are dispersed calibrated or uncalibrated, e.g. 100 to 500 .mu.m pseudospherical clusters (3) formed from refractory metals such as Mo, molybdenum boride and/or B.sub.4 C.As a result of the presence of these clusters, improved mechanical properties are obtained compared with those of pure B.sub.4 C.
