| Abstract: | titanate ceramic including Sr2 was produced with,self- propagation high-temperation synthesis (SHS )technology. The according to the chemical reactive systems, it was found that the Tad for titanate was much higher than the critical absolute temperature (1800 K), which implied that the SHS could be proceeded and densification. |

| Keywords: | titanate ceramic self-propagation high-temperation synthesis immobilization absolute combustion temperatures (Tad) optimization |
