Abstract
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.
