摘要

Continuous-fiber-reinforced SiC/SiC-based matrix composite materials, to be used in the first-wall blanket of a fusion reactor, were prepared by the infiltration of SiC cloth with SiC-based suspensions of various chemical compositions. The compositions were tailored with respect to the calculated activation in a fast-neutron flux. Liquid-phase sintering was used for material densification, using different sintering aids, such as Al2O3, Y2O3, P2O5, AlN, etc. The microstructures of the differently prepared materials were studied with scanning and transmission electron microscopy and microanalysis.
