| Abstract: | Si3N4-Re transmutation targets with 5wt.％ MgO,5wt.％ Y2O3 and different content of Re were produced by pressureless sintering method (heating to 1550℃ and holding for 3 h).The effect of different content of Re to relative density and bending strength of Si3 N4-Re transmutation targets was investigated.Then XRD,EDS and SEM were carried out to identify phase and observe microstructure and fracture morphology to analyze related mechanism. |
