Materials characterization of potassium sodium niobate based tellurite glass-ceramics

In this research, materials characterization of transparent glass-ceramics containing ferroelectric potassium sodium niobate (K0.5Na0.5)NbO3(KNN) crystals in a tellurite glass system were studied. The samples were prepared via an incorporation method. Glass-ceramics containing KNN crystals were succ...
