Abstract: Boron carbide (B4C)/polytetrafluoroethylene (PTFE) neutron absorbing composite materials were prepared by liquid phase sintering method at 380˚C. The themogravimetry-differential scanning calorimetry (TG-DSC) was adopted to characterize the sintering process while X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM) techniques were used to investigate the phase constitution and microstructure of the composites. In addition, the influence of B4C content on the mechanical and neutron absorbing properties of the composites was...
