Ratre, Mukesh (2011) Development of Y2O3 : Er2O3 system and its dispersion study in different media. BTech thesis.
Y2O3 : Er2O3 system has been developed and its dispersion properties have been studied in the present work. Erbium Oxide has been used as a dopant in to the Y2O3 matrix. The amount of Er2O3 has been fixed to 1 mol % with respect to 1 gm of Y2O3. The Y2O3 : Er2O3 system has been prepared by using 2 methods : Co-precipitation and Auto-combustion methods. The powders obtained have been calcined at a temperature of 900 ̊ C to develop the desired phase. Then the phase formation has been authenticated by XRD analysis which confirmed the cubic phase of the powder obtained after calcinations. The powders were dispersed in aqueous medium using PEG-400, PEG-6000 and TritonX-100 as dispersing agent. Then the zeta potential of the dispersed system has been studied at pH values between 7-8.
