چکیده انگلیسی
Transparent Y2Ti2O7 ceramics with excess Y content were fabricated by solid state reactive sintering in vacuum using Y2O3 and TiO2 powders as the starting materials. Phase composition, microstructure, density and in-line transmittance of the Y2Ti2O7 ceramics were investigated. The detailed results indicated that as Y content increased, the density and in-line transmittance increased at first and then decreased. And the highest in-line transmittance of Y2Ti2O7 ceramics is 49.9% at 1100â¯nm when the excess amount of Y to Ti is 2%. The effect of Y content on densification process of Y2Ti2O7 ceramics was discussed based on an assumption that oxygen vacancy defects were the dominated defects.
