Stillwellite glass-ceramics with ferroelectric properties

Structural evolution of LaBGeO5 transparent ferroelectric nano-composites

“…The corresponding LaBGeO 5 TFN has been prepared and shows second harmonic generation [15][16][17][18][19]. Second-order optical nonlinearity, d 33 , of surface crystallized LaBGeO 5 , LiBGeO 4 and Ba 2 TiGe 2 O 8 TFNs has been reported to be 0.13 pm/V, 0.7 pm/V, 7 pm/V, respectively [20].…”

Borogermanate glasses with a high terbium oxide content

“…Thus, difficulties listed above restrict strongly RE content in glasses. Lanthanum borogermanate (LBG) system is characterized by a wide glass-forming area, and LBG glasses can be melted at lower temperatures [1,2]. The available data [3,4] suggest that a high glass-forming ability should be retained with addition of most RE oxides into borogermanate matrix.…”

Evolution of ferroelectric LiNbO3 phase in a reactive glass matrix (LiBO2–Nb2O5)

“…A number of glass-ceramics comprising well-known ferroelectric crystalline phases (BaTiO 3 , LiNbO 3 , LaBGeO 5 , Sr 0.5 Ba 0.5 Nb 2 O 6 , SrBi 2 Nb 2 O 9 , etc.) have been fabricated and investigated for their polar and electrooptic properties [1][2][3][4][5][6].…”
