The thermal expansion property of cubic Cs_2FeSi_5O_<12> powder was investigated in the temperature range from 298 to 1273 K using high-temperature X-ray diffraction. The thermal expansion rate of cubic Cs_2FeSi_5O_<12> was lower than that of cubic CsFeSi_2O_6. Consequently, increasing the molar ratio of Si/Fe was effective for decreasing the thermal expansion rate of Cs-Fe-leucite compounds. Cubic Cs_2FeSi_5O_<12> showed a lower thermal expansion with the mean linear thermal expansion coefficient of 1.75×10^<-6>K^<-1> in the range from 573 to 1273 K., rights: 社団法人日本セラミックス協会
