Combustion Synthesis of Alumina-Based Multiphase Foam Ceramic

摘要：

　　Al2O3-TiO-TiO2 multiphase foam ceramic was prepared with Al powders and TiO2 powders by combustion synthesis,Direct observation and metallographic microscope indicated that the pore diameter is 100~6000μm,and Archimedean method showed that the porosity is 35~50%.The influencing factors of the pore diameter and porosity and,the effects of adding SiO2 on compression strength of the Al2O3-TiO-TiO2 multiphase foam ceramic were discussed.It was shown that the addition of proper high temperature foaming agent can increase porosity and adding SiO2 can decrease porosity.The Al2O3-TiO-TiO2 multiphase foam ceramic has good mechanical properties and high-temperature resistance.
