Influential Factors of SHS-Densification Methods of Solidified Nuclear Waste in SrTiO3 Synroc

Through self-propagation high–temperature synthesis (SHS), SrTiO3 in which Sr2+ had been included was solidified. The actors permitted to the solid dendification were analyzed by experimentation. Optimal process parameters were obtained for preparing SrTiO3 and composites, including 56% of density of preform, 10 MPa of pre-pressure P1, 4 s of pressing time t1; 300 MPa of high pressure P2 and 8 s of dwell time t2 at high pressure period.
