摘　　要：以Al、Cu2O、ZnO、SnO粉体试剂为原料,在自制的燃烧合成装置中采用高温燃烧合成-喷射法制备了Zn2SnO4微纳米颗粒。利用XRD、SEM和FTIR对其物相、形貌和红外谱学性质进行了表征。通过反应机理分析得到了生成Zn2SnO4的总反应式,反应体系中的三个铝热反应为自蔓延高温合成反应提供必要的能量保证,Cu2O的高温分解带来的气体效应是促成微纳米颗粒喷射的主要原因。Zn2SnO4 micro and nano materials were prepared by self-propagating high-temperature synthesis and injection technique in a self-made combustion synthesis device with Al,Cu2O,ZnO and SnO powder mixture.The structure,morphology and infrared spectroscopy were characterized by XRD,SEM and FTIR methods.The total reaction formula of Zn2SnO4 was obtained by analyzing the reaction mechanism.Three aluminothermic reactions provide the energy guarantee for the self-propagating high-temperature synthesis.The gas effect caused by the decomposition of Cu2O at high temperature is the main reason for the injection of micro and nano particles.
