摘要
采用自蔓延高温合成(SHS)与加压致密一体化技术制备了包容锶核素(Sr2+)的钛酸锶(SrTiO3)人造岩石固化体.通过实验分析SHS产物致密化的影响因素,确定了钛酸锶反应体系自蔓延高温合成时的最佳工艺参数:预制块相对密度为54%左右;预压力为10MPa,加压时间为4s;致密化时高压压力为300MPa,高压保压时间为8s.
SrTiO3 in which Sr^2＋ 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.
