Abstract

An ordered microstructure was discovered in the TiO2 doped LiNbO3 system prepared by using conventional floating zone melting crystal growth method. The microstructure of the obtained material was identified as a combination of Li1+xNb1-xTi xO3 (called as phase M) solid solution crystal, which had superstructure in nanometer scale and self-organized regular array of micrometer-sized Li2TiO3 rod precipitates within phase M single crystal domain. This kind of unique material rates as a "crystal composite". Detailed electron microscopic investigation revealed that there was certain crystallographic relations between phase M and Li 2TiO3 rods. The trigger for this formation mechanism is considered to be interfacial energetic anisotropy of the phase M solid solution.
