Abstract

Abstract

SrTiO₃ in which Sr²⁺ is included was solidified by self-propagation high-temperature synthesis (SHS). Some influential factors on the solid dendification were analyzed by experiment. The optimal process parameters for preparing SrTiO₃ and composites were determined as the following:the preform density of 56%; the pre-pressure of 10 MPa, the pressing time of 4 s; the high pressure of 300 MPa, the dwell time of 8 s under high pressure.
- strontium titanate,
- self-propagation high-temperature synthesis(SHS),
- densification,
- parameter optimization
