Surface Crystallization of Lithium Niobate on Silicate Glass

抄録

LiNbO₃ was crystallized with orientation along c-axis on the surface of a glass of the composition 35Li₂O⋅0Nb₂O₅⋅35SiO₂ (in mol%). The dense surface layers were composed of fibrous-grain crystallites, and the thicknesses were controllable by changing heating temperature and time. Kinetic analysis indicated that crystallization of LiNbO₃ was diffusion controlled.
