Abstract

Crystalline phases and second harmonic (SH) intensities in crystallized glasses of K₂O-Nb₂O₅-SiO₂ are examined, and the correlation between them is clarified. Crystallization behaviors depend strongly on SiO₂ contents, and three stable crystalline phases of KNbSi₂O₇, K₃Nb₃Si₂O₁₃ and KNbO₃ phases are formed in fully crystallized glasses. The crystallized glasses consisting of only perovskite-type KNbO₃ phase are fabricated in the glasses with high K₂O contents such as 40K₂O·20Nb₂O₅·40SiO₂. The crystallized glasses containing KNbSi₂O₇ or KNbO₃ phase show large SH intensities. The formation of K₃Nb₃Si₂O₁₃ phase is confirmed, and it is also demonstrated that this phase exhibits a second-order optical nonlinearity. Prior to the formation of three stable crystalline phases, it is found that various kinds of metastable crystalline phases showing second harmonic generations are formed. A transparent crystallized glass consisting of a metastable phase is fabricated.
