The aim of this work was to prepare phase pure and dense EuTiO3 ceramics and to establish their infrared reflectivities. Two kinds of stoichiometric powder mixture (Eu2O3+Ti2O3 and Eu2O3+TiO2) were used as precursors for shaping green bodies by cold isostatic pressing. Dense bulk samples were prepared by pressure-less sintering in reducing (Ar+7%H2, 100%H2) conditions in a temperature range of 1300–1650 C. The sample prepared from Eu2O3+TiO2 powder mixture sintered in pure hydrogen at a temperature of 1400 C for 2 hours exhibited a relative density higher than 95%TD and 100% phase purity, which resulted in its high infrared reflectivity affected by neither low density nor phase impurities
