Preparation of potassium sodium niobate in tellurite glass system doped with Er2O3
In the present study, potassium sodium niobate (KNN) doped with Er 2O3 in TeO2 glasses were successfully prepared using melting-quenching method. The glass composition of 70KNN-30TeO2 mol% doped with 1 mol% of Er2O3 has been chosen. A batch was subsequently melted at 800°C and 900°C for 30-60 min an...
