Abstract:
A method of manufacturing a translucent SrxBa1-xNb2O6, x=0.2-0.7, comprising the steps of:ball-milling equal weights of SrCO3 and BaCO3 separately with Nb2O5 powders to form a SrCO3/Nb2O5 mixture and a BaCO3/Nb2O5 mixture, respectively; calcining said SrCO3/Nb2O5 mixture and said BaCO3/Nb2O5 mixture in air at 800-1050Â° C. for 1-4 hours to produce SrNb2O6 and BaNb2O6; mixing and then pressing an amount of each of said SrNb2O6 and BaNb2O6 to form a pellet; sintering said pellet in oxygen at a temperature to form a sintered pellet; and isothermally heating the sintered pellet in oxygen for 12 hours at 1260-1275Â° C. to produce said translucent SrxBa1-xNb2O6.
